I am trying to get as much light on my 75 gallon aquarium as posssible without adding CO2, because I simply can't afford it right now.

How hard is it to control algae between 2 and 2.5 WPG without the addition of CO2 or Excel?

Thanks!

Thank you! If there is something I left out let me know.

It is a 75 gallon, river pebble substrate, the age of the aquarium is about 2 years.

Before adding the few plants I have now I had always run the light about 12 hours a day. But that was with just the 40 watt T-10. Now I also have a fixture that I made with 2x 32watt T-8's.

And I was thinking about adding another. Making it about 2.2 WPG total.
