2 days ago my Clown loach caught ICH but not severely so I started to use Quick Cure which contains malachite greeen and formalin, this morning I was surprise to see that the ICH is gone , But should i continue to use med, i have been using 1/2 dosage but i have to transfer my leo plec to my big tank cause the med seems to be burning his skin. The cory's are fine and spotless and the 2 clown loach are ICH free at the moment, Should i continue to medicate and change 25% of the water after 3 days or should i stop right now?
