I have a 90 gal pentagon shaped tank. I recently upgraded my lighting fromit 2 24" t5, 2 36"t5 & 1 30" led. To 165 mh with 2 36" t5 and led strip. Is this enough lighting or shouldt I replace the 175 mh for a 400mh. have some sps In my mixed reef.

Pat,
I am assuming the tank is 24" deep and about 36" at its widest point?
IMHO 400 watts would be a bit overkill unless you hang it a good distance away from the water line. I think either two smaller 175 or just one 250watt woud be all that you need along with your T5's.
