Setting up a 70g 36x18x24. I plan on running a 250w HQI 20k over the middle of the tank but think the sides may be lacking enough light. Has anyone had any experience with these PAR 38 bulbs from Exotic ???
I was thinking or running 2 of these on the sides to suppliment, and are they enough to penetrate 24'' deep.
