Flanker you talk about not running a fan but I see one in your pics, do you think air is getting blown on your bulbs or just on the water? Nova Pro is still the best bang for the buck. I can post par readings if you are in doubt, or maybe reefraff will.
the sheild makes the light even worst, it blocks the light. and i had the fan on for the summer it was 105 at my house.
