Just an update. I got all of the hair algae off the rocks! It's taken about 2 weeks of solid water changes (30 gallons every day of just siphoning the algae out), and 2-4 weeks of above normal WC. I found out the source of the problem. I had LR in my sump and there was about an inch of detritus that would build up so fast that I couldn't keep up with it. So, I took the LR out of the sump and put it all in my old 55 gallon tank. So, now I have two tanks (55g is going to be just a FOWLR in a few months). I'm going to be ordering my new skimmer in a couple of weeks which is going to make it so I can power feed which will make all the coral and fish happy. So, now everything in the tank is back on track and all parameters have been perfect again for over two weeks. I have gradually got a few new fish over the past few weeks for I will post some new pictures of them. I got a Copperband Butterfly, a Tennenti Tang, and last a Naso Tang that is roughly about 7 inches!
