How Long Should I Leave My Lights On

High light tank with pressurized CO2 and major algae problems. How long should i be leaving my lights on?

If its high light and pressurized CO2 you aught to stick to a slightly smaller photoperiod. 6-8 hours aught to be plenty, anything longer and it won't be the plants gaining from the light levels, only algae.

Perhaps you could tell us some more about your regime as every detail will help.

Okay, thanks. I currently have them on for ten. I'll try cutting back a couple hours.

A few more details: lighting is four T-5 HO bulbs, at about 4 wpg. Pressurized Co2 at about 4 bubbles per second. I dose micro, and macro nutrients and nitrogen 3 times a week. 25% weekly water changes that i am upping to 50%.
