I made the idiotic mistake of not quarantining some new fish prior to introducing them into my 40g breeder. It was a stupid move I know and my tank paid the price. The new fish brought with them some kind of bacterial infection that left a white film like coating on their dead bodies. It killed all the bristlenose, angels, amazon puffers. I noticed the last amazon puffer prior to its death had one fin pinned to itself. I treated with one of apis products which left a few survivors. One albino cory, 3 ottos, and a pair of not so good looking plady. My real question is can the tank be saved? Is saving it an option or do i have to remove all the plants, sand, filter media, rocks, possibly remaining fish and bleach the entire tank? I have never had such a disaster before so any suggestions would be appreciated.
