I just started a 40G breeder. I was using 3 green chromis to cycle the tank. One came down with that disease and I just Fw dipped and then put into QT. Upon researching I saw an article Humblefish did on about the disease being permanently in the tank, I’m not with that at all, as I have two clowns in my bigger tank that I was going to put in that tank. Should I restart the tank and throw all the sand out along with the water, sterilize the tank and start over? There’s nothing in there but rock, water prefilter and sponge filter.
