Biological media is used which includes bio baki balls & ceramic rings. The biological media is taken from established aquarium. Bio balls & ceramic rings are highly porous & they allow beneficial bacteria to grow on its surface. More holes will allow more bacteria colonies.


Step 6: Use straws as outflow channels:


Setup biological filtration media
Use straws as outflow channels


For outlet I have drilled 3 holes in the container & have used straws as outflow channels. I have drilled holes in the SUMP using electric drill to allow water to flow out. I have cut the straws short & have attached it to the container to allow water to flow out.


Step 7: Use suction cups to attach SUMP to aquarium glass:

I have used normal suction cups to attach internal SUMP to the aquarium glass. I have turned on the stove & heat up a nail for making holes in the SUMP. 2 suction cups are enough to hold the weight of the SUMP but to be on safe side I have used 3 Suction cups for attaching SUMP filter to the aquarium glass.


Step 8: Test internal SUMP filter:

How to Install a Double Sponge Filter

August 07, 2019

How to setup a double sponge filter in aquarium:

Sponge filter allows water to pass through the sponge. The double sponge filter can offer mechanical filtration & there are no biological or chemical filtration media. But bacteria colonies begin to grow on large surface area of sponge & it will start offering biological filtration too. Such filters are available in various sizes & designs which depends on your aquarium. 


How to Install a Double Sponge Filter
How to Install a Double Sponge Filter


I am going to demonstrate how to setup a double sponge filter & I will also tell you why sponge filters are very important & how energy efficient they are because you will only need 1 air pump to carry out filtration in multiple fish tanks.


How to install double sponge filter in fish tank:

In this tutorial I will show the easiest way to arrange double sponge filter in aquarium:


Arrange double sponge filter in fish tank


Step 1: I want to change my old filter:


DIY Aquarium Double Sponge Filter
DIY Aquarium Double Sponge Filter


Sponge filter setup is very simple. You can buy a double sponge filter for as low as $8 & it comes with the complete package including the suction cups which can be used to attach filter to aquarium glass. I had a DIY twin outlet pump already working in my recently cycled gold fish aquarium. I have only 1 twin outlet pump to operate filters in multiple aquariums. To convert twin outlet pump into triple outlet pump I used a T-shape connector. Hence I am using only 1 pump to aerate multiple aquariums.


Step 2: Air pump specifications:


Air Pump Specifications
Air Pump Specifications


The air pump I am using is Aqua One Precision 9500 & it can drive 400 liters of water in 1 hour. Normal pumps have a single outlet but the pump I am using comes with double outlets. Each outlet has the capacity of driving 200 liters in an hour. There are 3 settings for your air pump which can let it operate at high, medium & low flow rates. The air pump can provide 5.2 Watt of power which makes it economical as compared to other pumps. I am using a sponge filter that only needs an air pump to operate it so the whole setup is energy efficient.

Also you can buy this Sponge Filter: Double Sponge Filter Online


Step 3: How twin sponge filter works:

Double sponge aquarium filter
Double sponge aquarium filter


In my previous video I have setup a DIY internal bottle filter. I also mentioned that I have already ordered a Sponge filter on Ebay [1]. Adjust height of the telescopic tube which can release water [2]. The water will be sucked by the sponges & all the waste particles will be removed from the water before water enters the telescopic tube. The water is pumped out from the telescopic tube outlet. 


                        Air Tube at back of main tube               |  Water is sucked from both ends 
                                   pushes air down                          (sponges) & flows through main tube


I have removed both sponges & there is an air tube at the back of the telescopic tube [1]. It pushes air down which escapes through the main tube & creates suction [2]. Water is sucked from both sides & it flows through the sponges all the way up & goes back into the fish tank. All the waste particles or debris will be trapped inside the sponges.


Step 4: Attach sponge filter to aquarium glass & test it:


Attach filter to aquarium glass & test it
Attach filter to aquarium glass & test it


When I lower the sponge filter inside fish tank I feel some resistance because air is trapped inside the sponges. Pressing the sponges will release all the trapped air. You can see in the video the air bubbles are coming out when I squeeze the sponge. I am lucky that my filter comes with suction cups which can be used to attach filter to the tank glass so even though there is still trapped air inside the sponges, I can attach filter to the aquarium glass using suction cups [1]. I am attaching an air tube to the filter which connects sponge filter to the air pump [2].


Step 5: Design T shape connector to run 2 aquariums with a single air pump:

                                     Design T connector             |          Test double sponge filter


In my case 2 aquariums share the same air pump & I am going to discuss how to do it. This T shape connector can help me in creating multiple connections [1]. I can simply convert double outlet air pump to triple outlet. Now I have successfully setup my double sponge filter in aquarium. I will turn on the air pump power to see how it works [2]. Filter is working fine & I can watch bubbles are coming out & flow rate is not that high because I am sharing one air pump for running multiple filters.


Pros & cons of twin sponge filter:


Pros & cons of twin sponge filter


Twin sponge filter does not hold biological media but it can still provide biological filtration because colonies of bacteria begins to grow on large surface of sponge. So it can offer biological filtration along with mechanical filtration which keeps tank clean. However, double sponge filters do not look tidy & hobbyists do not like them because they are oversize & have 2 visible sponges. The maintenance required for twin sponge filter is lower than other types of filters. They are cheap & are suitable for fry aquarium because fry fish could be sucked into the intake of normal filters.

How To Build Overhead Sump Filter

August 05, 2019

How to build DIY overhead SUMP aquarium filter:

Aquarium filter is your best friend when it comes down to processing waste which is generated inside the fish tank. Aquarium filters can either be powered by an air pump or it can be powered by a water pump. In this article we will discuss how to build a DIY Aquarium overhead sump filter which is operated by submersible water pump.

Material:

The material used to build DIY overhead SUMP filter is listed below:
  1. Container or a planter
  2. Aquarium pump
  3. Selley's silicone
  4. Biological & Mechanical Filtration
  5. Clear Vinyl hose

Equipment:

The equipment required to build an aquarium overhead filter is listed below:
  1. Electric Drill with paddle bit
  2. Silicone Gun

DIY SUMP filter:

Watch video tutorial about DIY SUMP filter:

DIY SUMP Filter

Check out step by step tutorial about how to build aquarium filter:

Step 1: Find a container for the SUMP

Choose a container which fits perfectly on top of the aquarium, & which could hold enough bio media to process fish waste in the tank. The container can be used as an overhead SUMP if it has enough height for holding water, & contains plenty of bio media to produce sufficient bacteria colonies needed for your aquarium.


Use an electric drill with paddle bit & drill 2 holes for the outlet which would be exactly the size of the outlet hose. One outlet hose would be sufficient in most cases but in this project 2 outlets are used. 1 hose from outlet will distribute water on the surface level of aquarium & 2nd outlet will push water to the bottom of aquarium to make sure clean water is evenly distributed inside the aquarium.

Select a paddle bit that matches the size of the inlet hose & drill a hose on one end of the container. The height of the hole will determine how much water the SUMP will hold.


This container is actually a tool box with several compartments separated by dividers. I have removed all the dividers & there are only 2 compartments left. Compartment 1 is used for mechanical filtration while compartment 2 holds the bio-media. Water from the inlet hose hits the mechanical filter media first then it enters the compartment 2 & finally it flows back to the aquarium using 2 outlet hose. 

Step 2: Assemble the pump & attach it to the aquarium

Assemble pump & connect it to your aquarium
Assemble pump & connect it to your aquarium

The aquarium head pump can run efficiently in small, medium & big home tanks. A pump can run efficiently & can meet the requirements of any filtration your tank requires. It is advisable to use aquarium head pump because it will not disturb your daily activities & will provide the best filtration system your fish needs.

Connect the pump to the holder with suction cups which is used to attach pump to the aquarium glass. Connect the pipe to the pump so water is sucked from the bottom level of the tank. It is always good to attach an end piece which has small holes so that pressure of the pump doesn't hurt the fish. Attach a flexi hose to the top end of the pump. Water will flow through the pump & will enter the filter through the flexi hose.

Powerhead pumps can generate substantial power with quiet operation. It is durable & can perform reliably in aquariums. Powerhead pumps are sold in multiple sizes to serve smaller & bigger aquariums.

Aquarium pumps run by generating pressure differences b/w intake & outgoing valves.

I am using a submersible pump in this tutorial. Submersible pumps work efficiently inside water & have smaller sizes. The drawbacks of using submersible pump is that they produce heat & they could end up overheating your tank. Also it is recommended to take care of the wiring to avoid shocks because this pump is set inside water.

Step 3: Connect inlet & outlet hose

Silicone is clear & it looks like a gel. Temperature has no effect on silicone & it is not sensitive to chemicals, moisture & weathering. It is advisable to use silicone in aquarium related DIY project.

Setup of silicone tube in gun
Silicone Gun

Installing the silicone tube into the silicone gun is easy. All you need to do is to press the release at the back of silicone gun using your thumb which releases the plunger at the rear of the silicone gun. Pull the plunger all the way back & install the silicone tube into the silicone gun, the nozzle of the silicone tube should be facing the front. Push the plunger tightly into the rear of the silicone tube, & remove your thumb. Tube is installed & ready to be used now. Cut the silicone tube cartridge & it is advisable to make a cut which matches the size of the hole b/w the surfaces that you want to seal. The inner seal can be punctured by pushing a pin & silicone gel is allowed to come out from the cartridge.


Selley's silicone can be used & it takes 48 hours to cure & become aquarium safe.


Insert the flexi hose into the inlet hose & seal it to the SUMP using silicone. Apply the silicone on the gap b/w flexi hose & container outside, & it is advisable to use some silicone on the inside too so that there are no leaks in the SUMP. Excess silicone can be removed.

Also seal the outlet hose which has 2 hose, 1 flexi hose & 1 clear vinyl hose. Again put some silicone on the space b/w outlet hose, & container on the outside & inside as well. Wait for 48 hours & test for any leaks. If there are leaks in your SUMP, then apply more silicone.

Step 4: Filtration

The 3 types of filtration used in aquarium are mechanical, chemical & biological. Mechanical filtration is the simplest of all 3 types, & it is very important for fish health & maintenance of tank.

Mechanical Filtration:


Order of mechanical filter media

Order of mechanical filter media

It is advisable to use Coarse foam in the top layer which will catch all the large debris followed by a medium foam & then a fine foam to catch all the small waste particles. Using mechanical filter media in this order will provide efficient mechanical filtration to the overall overhead sump with an assurance that none of the micro pores in the biological media will get clogged by the debris. Altering the order of mechanical filter will affect overall performance of the filter & over time the efficiency will be reduced.

Biological Filtration:

Biological tank filtration is very important of all types of filtration. The lack of effective biological filtration could be the reason behind the death of more fish than any other reason.

Bio-media used in aquarium overhead filter

I have used ceramic rings & bio baki balls as bio-media.

Ceramic rings & any other form of ceramic media offers a perfect home to beneficial bacteria which is essential for the aquarium & wellbeing of the fish. Ceramic media increases the surface layer through tiny pores inside the media & provide more space for the bacteria to cling on & grow. The main advantage of using ceramic ring over any other media is that ceramic media can hold both nitrifying & de-nitrifying bacteria.

Bio baki ball is a breathing bio ball fired by high temperature. It is the best material for generating nitrifying bacteria.

It can restore the natural quality of water, & offer the best living environment for your aquatic pets.

Step 5: Setup an overhead SUMP filter

Setup an aquarium overhead filter
Setup an aquarium overhead filter

Place the overhead sump filter to the aquarium, ideally placed on top of the glass & evenly distribute the weight of the filter over the glass. Connect one end of the inlet hose to the powerhead aquarium pump which sucks water containing waste particles from the aquarium & pushes it up to the filter. The water hits mechanical filter media which removes all the waste particles & then enters biological filtration zone. Push both outlets hose down the fish tank which allows the clean water to flow back to the aquarium. Turn on the power & let the water run through the filter. 

It is strongly recommended to cycle the bio media first in a newly setup aquarium & allow the filter to run for a few days so that sufficient good bacteria grows inside the filter before adding fish to the aquarium. It is always good to add live bacteria to the new filter & it is advisable to add some cycle media to the existing bio media which will speed up the formation of the bacteria colonies.

It is recommended to use new hose for inlet & outlet, & do not wash filter using detergents because it is toxic to fish. Also wash filter media gently because good bacteria grows in this area & you can lose them. Also use a SUMP with height so that it can hold sufficient water & enough bio-media which is very beneficial for the fish health.

How To Build DIY Aquarium Top Filter (Tank Overhead Filter):

Every aquarium needs a quality filter to keep the water quality clean and also maintain good health of the fish. Store bought filters can be efficient but they do not fit every aquarium. Building a DIY filter is very easy as long as you know the basics and are not shy of getting your hands dirty. DIY Aquarium top filters are more efficient than the conventional filters such as it can cut down the tank maintenance, can be easily modified and updated and could be turned into an aquaponic.

Aquarium Overhead Sump Filter

How To Build DIY Aquarium Top Filter

An aquarium top filter is sometimes also called an overhead sump filter if it can hold water. This video is a step by step and detailed tutorial on building a DIY aquarium top filter which would be able to hold water and will offer powerful mechanical and biological filtration capabilities to the entire system. We have provided all the steps required to make DIY tank overhead filter.

How To Setup An Aquarium Top Filter:

Check out the full tutorial about how to make top filter for aquarium:

How to make top filter for tank

I have added a step by step tutorial about how to setup an aquarium top filter with screenshots:

Step 1:

Canopy of overhead sump filter
Step 1: Overhead sump filter box

Find an appropriate container that can hold water and doesn't bow over time and most importantly something that would fit on top of the tank. Source all the plumbing supplies such as PVC pipe, elbow, connectors, gasket, bulkhead and test if it can fit together.

Bulkhead are expensive and can be burden on the pocket if bigger size is required for the aquarium top filter. I would suggest a cheaper option of going with male and female adapters with threads and buying a gasket.

Step 2:

Drill holes in the channel drain & tray
Step 2: Drill holes in the channel drain & tray

Drill holes for the inlet hose and outlet hose [a]. Connect all the plumbing to see if it fits [b]. Build a tray to mechanical filter media so it doesn't touch the water in the overhead sump [c].

Step 3:

Use silicone to properly seal all connection
Step 3: Use silicone to properly seal all connection

Use aquarium safe silicone to properly seal all connection [a]. Male and female adapters with a gasket doesn't need silicone but in my opinion silicone should be applied since these connections are permanent [b]. Connect the tray next to the hole for the inlet and take necessary measures to stop mechanical filter media from sliding off the tray [c]. There is no harm in using more silicone as it could be easily wiped off and since overhead filters are usually hidden under the canopy then could be left the way it is.

Step 4:

Fill filter with water to discover leaks
Step 4: Fill filter with water to discover leaks

Test the aquarium top filter for any leaks by filling it with water and leaving it for couple of days. It will also help in determining if the container is suitable to hold the amount of water. If there are any leaks, then they could be fixed by applying some more silicone. It is also a good time to adjust plumbing if required.

Step 5:

3 types of filtration are used including mechanical, chemical & biological. Mechanical filtration is the simplest type which is important for the health of the fish, & stability of the tank. It removes particles of uneaten fish food, fish waste, & other debris present in the water. Mechanical filtration is the first level of filtration process & should be placed next to the inlet. It also increases the colonization of good bacteria.

Foam order in Mechanical Filter
Step 5: Foam order in mechanical filter (coarse, medium & fine)

Foams can be used to provide better mechanical filtration. You can use 3 stages of foams for best filtration. Water should hit foam first when it enters filter. Foams should be placed in this order: coarse, medium & fine which will ensure all debris from the water is removed before it leaves mechanical filtration zone.

Step 6:

Setup biological filter media
Step 6: Setup biological filter media

Biological filtration lies at the very end & it is the most important component of the filter which changes ammonia (dangerous for fish) into nitrates (not that harmful), & it can be removed by changing water regularly.

Ceramic media used in the biological filtration includes Aqua One Ceramic Noodles [a], & Aqua One Premium Sub Ceramic Substrate [b].

Biological filtration generates biological stability in the aquarium by providing the best environment for beneficial bacteria. Aqua One BioNood Ceramic Noodles can be used in the filter because they are extremely porous & provides the best environment for growing beneficial bacteria. Aqua One Ceramic Noodles can be used in both fresh water & salt water tanks.

Aqua One Premium Sub Ceramic Substrate is a very porous biological media that offers the best environment for the generation of denitrifying bacteria. Sub Ceramic Substrates are very important for healthy & productive biological filters. Aqua One Premium Sub can be used in both fresh water & saltwater tanks.

I have used pre-cycled ceramic media [c] but it is recommended to wash fresh ceramic media before adding it to the filter.

Step 7:

Setup plumbing & stuff
Step 7: Setup plumbing

After finding no leaks in the sump, it is time to connect all the plumbing & stuff. I cut a small piece of PVC pipe to join the adapter to the elbow [a]. I cut another piece of pipe to attach it to the other side of the elbow that will go down the aquarium [b].

Step 8:

Connect filter to the aquarium
Step 8: Connect filter to the aquarium

My aquarium is pre-cycled & there is lots of good bacteria inside the filter media so I connected the filter to the aquarium [a] but it is recommended to cycle your aquarium first if you have not cycled it & allow good bacteria to grow inside the filter before adding fish to the aquarium.

Water from the aquarium will enter the filter through blue flexi hose [b]. After turning on the pump, you will see water flowing through the mechanical filtration dripping down the tray which creates disturbance on the surface level of the filter, & enhances the oxygenation of water, & helps bacteria colonies to grow. The water is flowing down the outlet with a good flow rate & the sump is not filling up which is a good news.

Not all the biological filter media present in the bags are fully submerged in the water [c] which is not a big deal because I have heaps of bio media in the sump.

I connected the lid to the filter [d]. Since I have moved the biological filter media & disturbed the bacteria colonies so I have added some live bacteria to the aquarium & to the filter as well.

Material:

  1. A container that can hold water
  2. Aquarium Safe Silicone
  3. PVC pipe and 90 degree elbow
  4. Male and Female adapters with a gasket or bulkhead

Equipment:

  1. Electric Drill with paddle bit/drill bit or Soldering Iron

Setup Filter Media In Aquarium Top Filter

July 31, 2019

How To Setup Filter Media in Aquarium Top Filter:

In order, to keep the fish healthy, it is strongly suggested to clean the aquarium water using a filter. In this article i have shared a video that shows the best way of setting up mechanical and biological filtration in aquarium top filter. Adding chlorine neutralizer to aquarium water ensures that there is no chlorine present in the water which could potentially destroy all the good bacteria present in the filter.

Watch how to setup filter media in an aquarium overhead filter in a video tutorial shared below:

Aquarium Overhead Filter Media Setup Guide 



How To Install Filter Media in Top Aquarium Filter
How To Install Filter Media In Top Aquarium Filter

Every aquarium filter includes a few necessary parts such as mechanical filtration, biological filtration & chemical filtration.  Mechanical filtration takes out waste matters from aquarium & this component is best placed at the top of the filter or next to the inlet. Then comes chemical filtration, which removes chemicals from water and is best placed between mechanical and biological filter media. The last and most important component is biological filtration which changes ammonia (harmful to fish) into nitrates. Ammonia is released from fish waste.

Tips For Aquarium Filter Media Setup:

  • Step 1:

High quality foams provide better mechanical filtration. 3 layers of foam can be used for maximum efficiency. This is the first point of contact for water when it enters the filter. And setup of filter media should be in this order: coarse, medium & fine. An efficiently setup mechanical filtration will ensure all waste from the water is removed before water enters biological filtration zone.

Foam Order: Coarse, Medium & Fine
Foam Order: Coarse, Medium & Fine

  • Step 2:

Biological filtration consists of ceramic media such as Aqua One BioNood Ceramic Noodles, & Aqua One Premium Sub Ceramic Substrate:

Set Up Biological Filtration
Setup of Biological Filtration

a. Aqua One BioNood Ceramic Noodles:

Aqua One BioNood Ceramic Noodles

Biological Filtration produces biological stability in your tank by offering the ideal environment for good bacteria. You can use Aqua One BioNood for this purpose. Ceramic noodles are very porous & creates the best environment for producing good bacteria.

There are numerous little pores in Ceramic media which cannot be seen by naked eye & all the good bacteria grows here.

b. Premium Sub:

Premium Sub can be used in freshwater & saltwater aquariums. Premium Sub is subjected to very high temperatures which produces tons of tunnels through it. The tunnels let good nitrifying bacteria that breakdown pollutants. The extremely pours let more good bacteria to enter your aquarium.

Aqua One Premium Sub Ceramic Substrate
Aqua One Premium Sub Ceramic Substrate

Toxins like Ammonia & Nitrite are broken down & converted into Nitrate which is less dangerous & you can remove it from your tank by changing water regularly.

Note:

In this video pre cycled ceramic media is added to the filter but it is recommended to wash new ceramic media before adding it to the overhead tank filter.

  • Step 3:

How water enters the overhead sump filter and how it travels through the filter media can be determined by the inlet and type of attachment. As seen in below image, holes are drilled in a plastic pipe and water flows through all these holes and is sprayed evenly over the mechanical filtration.


Drill holes in pipe to allow water to flow through the filter

Inlet hose which is a flexi hose in most of the filters can be connected to a powerhead at one end and the other end can be connected to the filter.

One end of hose is connected to the pipe
One end of hose is connected to the pipe & the other end is connected to the pump


  • Step 4:

After setting up all the components, powerhead can be turned on to test the flow rate and minor adjustment can be made if required.

DIY Aquarium Internal Filter In Under 20 Min

July 30, 2019

How to DIY aquarium internal filter in under 20 minutes:

The inhabitants release waste constantly as they swim in the aquarium. If fish waste is not eliminated on time, the toxins may stress fish & may eventually kill them. Also fish food & other particles can make water cloudy if it is not removed on time. Every tank needs biological filtration which will reduce the required maintenance. Mechanical filtration can help clean aquarium water & make it crystal clear using different layers of foam which stop waste particle & allow clean water to flow. When choosing the top tank filter for your aquarium, an internal filter could be just what you need for your tank because it is small & sit inside your tank, & it does not need room for a bigger external filter. Internal filter can circulate water, if it is operated with an air pump then it can provide aeration & it can clean your aquarium water & can hold enough bio media.

How to build an aquarium internal filter

Tools:

The tools required to build a DIY aquarium internal filter are:
  • Electric Drill
  • Knife
  • Scissor

Materials:

The following materials are used to build aquarium internal bottle filter:
  • Plastic Bottle
  • Air Stone
  • Pipes
  • Suction Cups
  • Coarse & Fine Foams

How to build internal aquarium filter in 20 minutes:

All the steps involved in making internal aquarium filter are provided below:

Step 1: Cut a bottle & drill holes

Making tank filter has never been that simple. I have provided a step by step video about how to build DIY internal filter for your aquarium in just 20 minutes. I have used a bottle as my internal filter for the tank. It will offer both mechanical & biological filtration & an air pump will be used to operate it.

Cut a bottle & drill holes

Drill small holes at the base of the bottle & then use a bigger drill to make these holes bigger. I am cutting the bottle with a knife somewhere close to the top half & the top section will be used for mechanical filtration & the bottom half of the bottle will be used for biological filtration. It is very important to use a knife with a sharp blade so that you don’t cut yourself & to finish it off with a clean cut I used a scissor.

Attach suction cups to filter

I drilled 2 holes on the side of the bottle for attaching suction cups. It can be used to attach the filter to the tank glass. I drilled last hole for the air tube. An air stone is connected to the end of air tube for quiet operation of the filter & for making many bubbles.

Step 2: Add biological & mechanical filtration media:

Mechanical and biological filtration

The bio balls will offer biological filtration. Any kind of biological filtration can be used. It is recommended to rinse the biological filtration media before adding it to your aquarium. To speed up the growth of good bacteria I put some cycled media from my DIY aquarium SUMP filter. It you want to build DIY aquarium SUMP filter then you can find the link below:

I usually use 3 layers of mechanical filtration in my DIY projects but to build aquarium internal bottle filter I am only using 2 layers of mechanical filtration media. One is a coarse foam which is attached to the cap of the bottle & the other one is a fine foam that will provide mechanical filtration. Water from aquarium will pass through the coarse foam first then it will pass through the fine foam & all the waste particles will be stopped & only clean water will pass through the biological filtration zone where good bacteria grows.

Step 3: Testing of DIY aquarium internal bottle filter:

Testing aquarium internal filter

The internal filter for the aquarium is ready & now it is time to connect it & test it. Connect the outlet of air pump to the filter. My DIY aquarium internal filter is working properly. All the disturbance is created on the water surface that will provide aeration. The results are better & you can see the mechanical filtration is catching all the debris. There are heaps of biological filtration media that speeds up the process of growing beneficial bacteria. The air stone can create enough bubbles to oxygenate the water which adds more oxygen to the water. No air pump is used in this project & everything is completed under 20 minutes. This way of making tank filter is inexpensive, efficient & fast.

Pros & cons of internal bottle filter:

Pros & cons of internal bottle filter

Internal filter can provide mechanical & biological filtration which helps in effective filtration of the aquarium water. It can hold enough bio media to help grow bacteria colonies. It can operate with an air pump which can make enough bubbles to oxygenate water. It is a cheap filter & does not require a pump. It cannot circulate water in the aquarium because in my setup I have a heater close to the filter & the temperature of the water in the right half is warmer than the water in the left half of the aquarium. It cannot provide chemical filtration which is another drawback of internal bottle filter.
