I have a 45 gallon reef tank and have been fighting a serious hair algae problem for some time. In my sump, I use a polyfilter,phosban, and carbon, even took out my bio balls, and do 10 gallon water changes every week...still no improvement. I was wondering if a refugium with macroalgae would help "out-compete" the hair algae and help absorb the excess nutrients (which dont show up on water tests).
