My 100 gal reef tank has had hair algae out of control for a year now and I'm starting to lose good coral specimens that are getting smothered.
I have 2 175W MH bulbs and 2 110W VHO Actinics that run about 9 and 8 hours respectively. I have lots of live rock for filtration and run a turbofloater 1000 constantly. My water chemistry comes up negative (even for PH4). I have tried starving it by stopping all suppliment and using lots of activated carbon. That only help moderately. I'm out of ideas.
I have some clams and lots of coral so I do need a lot of light. The tank is 3-4 years and is very mature. I did not have this problem the 1st 2 years.
Help!
