Here are my PAR readings on my T5 light system when I first setup. 4 rows of 2x39w with Ice Cap reflectors (312w Total). The Geisemann bulbs and Advance ballasts were about 3 months old. Actinic +, Midday, Aquablue, Pure Actinic. Bulbs 5" above water. This is a 125g 22" deep.
This is a recent shot after about 6-7 months with corals.
I feel I have fair color on my SPS. My original plan for this tank was a mostly mixed reef but my SPS have done well with color and growth (better than I expected) so I am leaning towards keeps more Scleractinians these days. I think my currently undersized skimmer and a few equipment failures are holding me back from getting great color/growth. I will probably add two more rows of T5's for a total of six along with a skimmer upgrade and two more nano stream 6055's. This should help make the SPS in this tank a bit happier.
