I've posted on here a few threads about my upcoming frag tank. It will be 22x27x11" with a frag rack on the left 2/3's. This rack will raise about 1/2-2/3 the way up the tank to allow higher PAR rating on the rack and multiple levels of "steps". Obviously SPS will be placed higher up and than LPS and z&p's. I'm new with the hydra's and LED's in general; I run T5's on my display. What light intensity should I start out on the Hyrda and how far up should I hang it?

Any suggestions are helpful! Thanks
