Hi all! I have been battling hair algae for a while (6 months +). I have attempted sea hairs- they don’t eat it. Crabs, urchins x2, lawn mower blenny (didn’t eat it), foxface(nope), Sailfin tang , peroxide on the rock (stressed corals and they are dying), changed all Ro/FI filters, lowered my lights from 12 hrs to 10hrs, less feeding, rinsing frozen food, shut lights off for 3 days, GMO, added peroxide to the tank water, have CUC’s, picked it off, ummm I think that’s all so far. My nutrients say 0 on ammonia, nitrites and phosphate and 5 on nitrates. I have a clam so I’m wanting to be careful with not making too much of an adjustment on lighting. All blue lights are at 60%, white at 20% and no red or green. I have the photon lights on a 120 gallon tank. Any other suggestions?
