I bought a new light for my 125g tank with MH lights and 50/50 flour. I am now developing a hair algea problem. I have researched the threads and gathered some info. My water parameters are what they should be including nitrates at 10 or less. I am feeding every other day frozen brime shrimp (small cube). I use RO water and my tank is very lightly stocked with 5 fish (damsels) and 1 lawnmower blennie. If I keep the right parameters with this go away like the diatoms when first set up 3 months ago? Anything else I can do/get to keep it from getting out of control? I also have 2 mushrooms, 1 anenome, and a tree coral. I had recently put into the water a reef supplement "Natural Trace" made by API which was recommended by the lfs for the soft corals. could that have caused the problem? Thanks!
