I noticed a small out break of green and red algae in my refugium. Do you think i need to change out my T8 fluorescent bulb? Should I look for one in the 3K range? I changed out the carbon bag. Also i noticed my cheato is brown on the bottom side of one of the clumps. I rotated it all around hoping it can re-grow. I keep my lighting on a reverse schedule, and do 5 gal weekly ro/di changes.
thanks
