My light

I have a 65g tank. 36x18x24... I am running 2 t5ho bulbs about 4 inches off the surface and 25 inches from the substrate. Not sure what kind of light this gives me..high or medium?? I am in a battle with some GSA. I have raised my co2 to the max and my po4 is above 10 as far as I can tell. Is my light to strong? Can I raise it more and solve the issue. It seems like the algae only grows from the middle of the tank down. Where the waterline is after a water change...and only on my anubis and large rocks, very little on my glass.

How much light you have depends entirely on the quality of the reflectors and ballast in the light fixture. What specific light fixture do you have? See Lighting an Aquarium with PAR instead of Watts for more information.
