Hi,
I can simpathize with your algae problem. I had an ongoing hair algae problem in my 110 gallon reef for 1.5 yrs. I almost threw in the towel on the hobby. I tried everything. Fed very little (2-3 times per wk), added every critter ever recommended. Purchaced top of the line ETSS Skimmer, Spectrapure RO/DI unit. As well as Carbon, phosphate, various nitrate filter media. Nothing put a dent in the problem. I had 100+ pounds of LR and a 4" sand bed. Yet found dispite monthly water changes and all the other buzzes and bells my nitrates remained fairly high. Because of this I was affraid to add any fish that may consume the algae, thinking that might totally tip the scales and crash the tank completely. In a last ditch effort I purchaced another 50 lbs of live rock thinking this may boost my bio filter and reduce the nutrient level.
The long and the short of it. Nitrates started dropping and I started adding a few tangs to clean-up the rocks.
Now 6 months later, with the new rock and 5 more fish than I had before feeding 3-4 times a day, I now have zero nitrates and zero, none, not a strand of hair algae.
I wish I had added the rock 2 years ago I would have saved a fortune on creatures and gadgets.
I am not recommending or suggesting that uping your biological filter by adding more rock is the only cure-all solution for hair algae problems. But just something to concider in the grand scheme of your reef. Think about it, one way or another you need to find balance of the nutrients in your system to resolve a hair algae problem.
Sorry for the long reply- But my story needed to be told,
Stevo
