I’ll go ahead and go on record and say this is not reef safe and does 100% affect your biome. I have a ICP before and after.. if you’re a jerk like me, I don’t recommend using it. It might be OK for softies and LPS but torches and SPS are not happy.. @vetteguy53081
All "reef safe" medications have the same issue - fish parasites are invertebrate animals. Anything "reef safe" dosed at levels safe for delicate corals is also going to be pretty much "disease safe" as well. Dosing high enough to cure fish diseases outright will likely cause other invertebrate problems.....
