I have a 75 gal
with a closed hood, 4x 96 watt PC
I have a slamming deal on a hang above fixture with 2x 250w MH
and 4x 54w T5 actinics and moon lights.
I will remove the enclosed hood and hang the new fixture above the tank from the ceiling. This will get rid of of the overheating problem.
but my question is -
Is there such a thing as too much light?
