Thank you Hoppy. Without your help I would have no idea because even looking at that chart just now, I am lost. I will see if they have the same type of bulb and color in 10W so I get 20W total light to prevent the need of CO2. The only reason is because I want to raise and breed CRS and CO2 could potentially become harmful to them unless I can get away with 1-2 bubbles per second at most with this lighting, would I?

PS: Yes I have the same fixture mounted on the other long end of the tank so that they are facing each other.
