Newbie here, 2 weeks into cycle for a 135 gal display tank w/50 gal sump. Pics posted here http://maast.org/forums/album.php?albumid=159

I have 4 retrofit T5s installed and I'm being told this is not enough for LPS from the local shops. I only have room for 2 more T5s, but I'm considering 2 250w hqi MH (double ended) if I can find them at a reasonable price. What is enough lighting? Is my current setup enough for SPS? Any suggestions?
