I have a 28g Nano-Cube that has been up and running for a year and a half. I keep getting brown algae on my rocks, sand bed, everywhere! I also have what I think is some kind of green hair algae. My zooanthids have been closed up tight for over a month now as well. Temp: 79, Salinity: 1.025, PH: 8.4, KH: 9, Calcium: 460, phosphates & nitrates: 0 - regular water changes. CF bulb is a year and a half old, will that cause all my issues? Any help would be appreciated. I tried to attach a pic of my tank below - I hope it works!
Thanks!!
