my tank is about 5 weeks, i think it is close to cycling, my salinity is fine, my nitrites is a little high, my ph is fine, i have a 55 gal with 42 lbs of live rock, 40 lbs of live sand, 3 hermmies, 1 powder blue tang, 3 puffers, and two triggers all young, you mentioned something about copper treatment, i am treating with a ick removal medicine, i bought a new filter and took out the carbon because according to what i heard the carbon basically will take the medicine away thus defeating the purpose of treating the ick, what about the copper? i heard a little about that before?
