Hello everyone havnt posted in a long time my 75 gallon has now reached its one year anniversary and I am now in the process of adding my first corals. I have been having nitrate issues and decided to setup a chaetomorpha refugium which is already been going for 3 days now. The giant nitrate spike started after I began to battle the green hair algea issue I was having after a couple black outs and a lot of toothbrushing rocks along with phosguard things are looking up. The video above is after the gha fight and I am wondering if I could be missing something besides the refugium to keep the algea in check?
