I have a 55g FO tank my water is in perfect condition but i continue to get only brown algae. I dont mind getting green algae but I hear brown algea means something is not right with the tank. I have had my tank for 1 year now. Im wondering if it is the light. How long does my light usually last or how often should they be changed. I have a 40W power-glo.
