Guys I need help. I am not sure exactly what I'm dealing with here. I want to say that it's hair algae on the rocks and diatoms on the sand but I'm not sure about the diatom diagnosis. I need to know what to do to get rid of it. My lights start ramping up at 11:30 and ramping down at 8:30. My nitrates are 7 and my phosphates are at .7. The levels of nutrients have been steady for a while now. The tank is 6 months old. Is this something that I should just wait out? Fish and corals all seem to be doing outstanding. I have a plate coral that is super puffy and an elegance that is nice and spread out. Please help!
