Help on treating ich

[Nano]

I always listen to what she says hahaha. Also once i qt my fish a few weeks down the road i dump a capfull of herbtana in the dt once in a while just to play it safe. Usually a day or two before a water change so there isnt excess stuff in the water. I don't kniw if I'm right or wrong in doing so but i only had the one outbreak, and it was in my dt so that's why I do that. Cause I'm sure there is still ich in my tank and i like to try to keep it at bay.
