What level are you keeping your co2 at? I've found that as long as I get the
co2 up to 25 - 30 ppm and keep it there any algae I have in the tank fades
away as long as I keep everything else in balance.

CO2 helps one thing grow in your tank and it ain't plants - it's algae

DO NOT USE CO2 - This is no troll - I've tried for one year now and it
makes black hair algae grow like mad - save yourself money and
trouble. Just don't do it.
