I changed my lighting. And took out all the rock and scrubbed it, and kept doing that piece by piece as the hair algae would pop up again. Scraped the sides of tank about every other day. Stocked it with many mexican turbo's, one lawnmower blenny (and I DO credit him with alot because he tummy was always HUGE when the hair algae was around, now it's always normal looking, he's probably starving now), 4 royal urchins, many crabs, and cleaned filters, pads etc very often. I did two 50% water changes within a month. Threw out about 50 lbs of rock so that I could get all around in the tank and made it easier to pull the rock I kept out for cleaning. It was hard and very frustrating, came VERY close to throwing in the towel on many occassions.
Another few of the other end of tank, algae free, it's completely gone.
