I have started a 55 gallon around 10 months ago and over the last few months have a serious hair algae growth problem. I have been using NOVA extreme T5s 2X39W-actinic (7 hrs/day) and 2X39W 10Ks (4 hours/day). I use RO/DI water with TDS monitor. I have only 3 small fish, a couple of softs and my nitrates, nitrites are zero with a normal pH. I have tried reducing lighting times, buying new bulbs, more frequent water changes, and better water flow-no luck in fixing the problem.
Any other thoughts to get rid of this algae?
