So I recently discovered a new fish I bought had ich, I have moved all my fish to a 10 gallon tank to quarantine but my question is: How long will the beneficial bacteria in the media from my well established 55 gallon live while I treat the fish in the other tank. In that tank I have (2) canister filters that are still running like normal. I taken everything out of the 55 gallon except for the sand, ghost shrimp and snails. The decorations were removed a couple of days ago and set outside to dry out. For now I've just been putting some fish food in there like normal.
