I am having a problem with hair algae as well. Its only growing on one specific rock, I ahve taken it out scrubbed it clean twice, cut my lights back and it still keeps coming back. Tank is only a month old, cycle finished Sunday and I added part 1 of a cleaning crew monday (6 ninja asteria snails, 5 margarita snails, 3 scarlet hermits and 10 red & yellow tip hermits) addid some pepermint shrimp tonight. I am only running a 10,000K light, I have been leaving the 300wt MH's off... I run the 10K for 8 hrs a day... I am not feeding as I have no live stock to feed, flow could be better, I am runnign about 500gph in a 90 gal. My SG is a little high but I dont see how that could lead to algea growth,
My asterias wont go near it neither will the hermits... Is there anything that will eat it? A lawnmower blennie perhaps? Any inverts? Would a phosban reactor help?
As far as tank, 90 gal, 130lbs of LR, 93lbs of LS,
Ammonia 0
Nitrites 0
Nitrates .25
Sg 1.026
Phos 0
Ph 8.2
I have been topping off daily and do 10gal on sundays...
