Hi, I have only had my bio-pellet reactor up and running two weeks and have noticed already that my algae on glass is much lower, my nitrates are low at 5 to 10 anyways, and it will be awhile before bio-pellets lower that.
I had the red algae it is a macro algae and you may have red macro algae, I tried everything, the hermits, snails, crabs and tangs would not touch it. I took about 25 lbs of the affected rocks out of the tank and scrubbed them off in the sink and then put the rocks on a cookie sheet and baked the rocks at 400 degrees for an hour and a half. That cured that problem, they are back in tank and will color up soon. Now I have zero red macro algae issues, never had the hair algae problem in this tank. In a past tank, I had the green hair algae, get extra snails and hermits that will help out. You may want to try different food, Elos has a good food that is phosphate free. Another fix is to an algae killer treatment, there are a couple of good ones, but be careful, I used it once too heavy and my brittle stars legs fell off - sad looking guy. If you use it, you may loose some inverts, so dose very little.
