If you're running 4 bulbs at 55w totalling 220 watts over a 55g tank, that's

just a warning... if no CO2 you go, the algae will grow....

I planned to only run 2 bulbs at a time. It comes with 2 x 10000K white
and 2 x Actinic blue. I was going to run the blues at nice and the
whites during the day. That way I have ~2 wpg at any given time.
