What algae and where, on the rocks like GHA?The oxydator w seems not to have an effect in my new tank ,a lot if alga and water is not clear.
I have put two catalysts and 12% peroxide, maybe I should add 3? Will also try it in the main tank to see
My tank has between 1200-1400liter
Have you IDd what is in your water bacterial.bloom etc and how old is your tank?
