lighting

With corner tanks fluorescents can be difficult to use as you can't usually use an array of fluorescent bulbs unless you have a rectangular tank. Best lighting option will likely be multiple small DE MH pendants. With your tank you may also be better running a larger 400W SE bulb in a large reflector such as a lumenarc III. You could then install a few 24" T5 bulbs around the reflector perimeter for supplemental.

Another option, if you're looking to increase growth switch your bulbs to a lower kelvin rating and switch out your actinic lighting to a brighter blue or purple bulb.
