How Do You Know a Tank Has Been Disinfected Well Enough?
How do you know a tank is safe to reuse after losing all your fish? I have a tank that used to hold neon tetras. Not too long after purchase they all succumbed to what I think was false neon tetra disease but I never got a definitive diagnosis. Despite treating with antibiotics they still died.
Since then I've emptied the tank, disposed of all the filter media and substrate, quarantined the plants, and washed the tank with rubbing alcohol and then soap and water. I've filled and rinsed the tank a few times and rubbed it down with vinegar to make sure no soap residue is left.
So is the tank safe to reuse now? I'd like to plant it and start it cycling, but I'm a bit afraid of putting fish in there and losing all of them because I failed to do something I should have done to disinfect the tank.
