I am going to be picking up a 90g tank later today and need to starting looking for lights. Will an 8x54w T5 fixture work on a 24" deep tank that is going to keep SPS and LPS or will there not be enough penatration? My other option would be to go with a 2x250w MH fixture with supplimental T5's. Any thoughts or what works on your 90g tank? Thanks.
