I'm nervous about treating fish with any chemicals to kill critters, fungi, etc. I'm setting up a new 125g in-wall mixed reef. It backs up to the fish room. I'll have two Q/T 29g BioCubes, one for small to medium fish, one for corals, then a 14g BioCube as a hospital tank.
So my question for everyone. Do you pre-treat your Q/T tank for ick, fungicide etc, so why or not ?
I can not figure which option. Add them before or watch and see if the fish has issues ?
