Well I think it is time to start over. We are moving in the next few week (any volunteers for tank moving day?), my tank is overrun with bubble algae, hair algae and aptaisa and the acro issues I have going on. To start over I only need new rock. What are the good sources for rock these days. The tank is a 120 and I like to go on the lighter side for rock. I think I will break off the few acros I have left and put them in my 45, along with the LPS, clams and zoas. Get some new rock and go. I may even go with sand, maybe just a light layer to keep my LPS from encrusting to the bottom.
