I have a skimmer. I didnt want to put it in the tank either but the fish which was the last Ill ever buy from petco, had ick and was hard to acclimate and I wanted to make sure It was completely acclimated before removing the copper. I did do two small 5 gallon water changes, but am planning to do a major water change to get rid of the copper especially because I plan to put some soft corals in the tank. The hippo tang is now fine and I will do a big water change this weekend and see if this helps the algae problem. Also I put in some base rock in my tank and it almost immediately grew purple, pink, and green algae could this be caralline ? can it just grow? Im pretty sure this isn't red slime or someother type of algae.
