I've had an out break of green hair algae, and it's hard to get under control. I will admit that I let my water quality get kinda bad before purchasing a new RO unit. I've been using the new RO unit for about 2 months now, it is putting out 0 TDS water, so the water quality is greatly improved. I had a TON of green hair algae...but it has improved. I hoped that with the frequent 2-3 week partial water changes that I would not see much new algae growth...but it is still growing...not nearly as fast...but still enough to be a pest. Any ideas on what I can do to get rid of it. In 10 years...this is this first time that I've had this problem. I tried sea hairs but they didn't want to go on the rock where my main problem is.
