Finding a balance is not easy. If your dosing EI, doing your WC's, have pressurized C02 at stable levels and a good substrate. What's left is your lighting. Too much light seems to have always been my enemy. Raise it off the lid, have it shut off mid photo period for an hour and clean as much algae out of your tank as possible.
All dead or decaying leaves must go. Pull your driftwood out and clean it well. If your ready to give up you should try the "one two punch" method that is posted on this forum. It's a treatment with peroxide that will slow/kill the algae growth and let you get a grip on the tank.
How old is this tank?
What are your water params.
Ammonia, Nitrite, Nitrate, KH, GH, PH, Temp??
