My tank has been up and running for a bit over a year. Its a mixed reef with mostly LPS and several fish. Some HA started gettin all over due to my phosphates. Found my phosphate issue (dead chaeto in sump)...fixed that. I am also running kalkwasser and GFO. So, I need to remove the existing hair algae. Ive been reading tons of success stories about h2o2 and full tank dosing. I am in my 3rd day and am noticing it starting to kill the algae. I am dosing 2ml's per 10gallons. Anyone else doing this?
