Thanks, I have been getting hair algae at 10ppm, I kicked it to 20ppm and it went away in both my 30gal tanks the same day after about 10 days at 20ppm . When it went back to 10 ppm my hair algae came back in both my 30 gal tanks the same day! CO2 and WPG is also the same in both tanks. Guess I will be keeping it at 20ppm.
