Remove other fish of your aquarium to another tank with clean, fresh & de chlorinated water. Make sure you use a different net for other fish because fin rot can spread from one fish to another if you are using the same net. Make sure you do not keep both affected & unaffected fish in the same tank because fin rot can spread from diseased to un diseased fish.

It is very important to wash the aquarium & aquarium accessories. Then take out all water from the original aquarium, & remove its accessories, including gravel.

Wash the aquarium with hot water. Avoid using soap or detergents as it is dangerous for the fish. Use aquarium safe accessories for accomplishing any job. You can use paper towels to reach the gaps of the aquarium & it is recommended to clean everything well.

Soak every accessory of the aquarium in hot water for 5 to 10 min. If your aquarium is stocked with live plants, soaking them in lukewarm water is suggested. Take your plants out of water & allow them to dry.

Wash your tank gravel with warm water & hoover your gravels with a small vacuum to remove any dirt or other debris present on them.

Complete aquarium water change is required. After your aquarium is clean & dry, put gravel & other accessories back in the aquarium. If your aquarium is not cycled, do a complete water change. Ensure your aquarium water is maintained between 80 to 82 degree Fahrenheit.

If you have a cycled aquarium, which means that you have enough bacteria already established on the aquarium surfaces & accessories, you can change fifty percent water of aquarium, or can do subsequent water changes of small amounts.

If your aquarium has a filter, fill a bucket with fresh aquarium water & wash your tank filter with the bucket water. After cleaning your aquarium filter, you can set it up in your aquarium. Using tap water for cleaning the filter is prohibited because it can kill beneficial bacteria that is built up inside the filter. Fresh water has chlorine which kills good bacteria. Beneficial bacteria converts harmful chemicals that releases from fish waste into less harmful chemicals which can be removed with regular water changes.

Check pH of the aquarium water. Before adding fish back in the original aquarium, do a pH test to make sure your water quality is fine. The water pH must be between 7 to 8 & the toxic chemicals that releases from fish water quantity should be no more than 40 ppm.

After your tank water is suitable for the fish, release the fish back in the main aquarium, also add the fish having fin rot. Then use medication for treating the infected fish. Cleaning aquarium together with medicines can help in proper curing of fin rot.
