I using the middle chamber of my biocube as a refugium i just wanted to know if anyone else was and if so how long are they leaving the light on the refugium right now i have it coming on when the tank lights go to night lighing. My Phosphate are a little high and I wanted to know running the light longer would help see i have some Chaetomorpha Algae in my refugium was thinking if light was on long maybe to would pull more phosphates from the water.
