I'm making up a fish first aid kit and saw this treatment at the store. The few tidbits I've found on it haven't lead to anything conclusive, but my main concern is if my fish come down with something and I have to use it, will I have to recycle the tank? It claims to kill bacterial infections like fin rot while also killing fungal infections.

Just hoping someone here has had first hand experience with this medication and can answer this for me. If not I'll probably just quarantine any sick fish and do daily changes to get the bacteria/fungus out of the main tank (I wonder if that'll hurt my bio filter as well, I wouldn't think so but...)

Anything helps! Thanks! *celebrate

If you have decor and gravel in your current tank, treat the tank exactly as directed with the medication. Then after you have completed the medication course. drain and refill tank with fresh water. This way the bacteria and fungus on your plants and decor get killed off and don't get carried over when the new water is refilled. As for in the title you mentioned "biological filter" I'm sure you need to remove the active carbon out of your filter for the medication course. If its in the filter media itself there is really no choice but to remove the filter during this time. Keep the pump running of course for oxygen.

Meds that are bacterial treatments can kill off the beneficial bacteria in the tank. Its just best to assume its going to happen and be ready for your tank to recycle. Keep track of your ammonia while doing any treatment. If tests show ammonia you will need to do water changes to keep them barely detectable though out the treatment and after until the ammonia and nitrite show zero again. Be sure to do the water changes before treating the tank so your fish can be exposed to the meds longer before the next water change.
