So my SW tank has been set up for over four months now, last month this algae started to appear, it quickly overtook my tank, it grows everywhere and anywhere. I do maintenance on my tank more than once a week, even within a few days it looks horrid again because of this algae, it grows like mad so I've started to cut down my hours of light. It's a 34 gallon, ppms - 0 nitrite, 0 nitrate, 0 ammonia and 8.2 pH, here's some pictures I took before I done maintenance today if anyone can ID it for me, the last one is of some other bright green growths in my tank, also wondering what they are if anyone could tell me, many thanks.
