400W MH's inhibiting Photosynthesis......

[pocilipora]

Well its been 2 months since Ive changed from 250 Iwasakis, to 400 watt 10,000k german bulbs. The tank went through a small diatom algae bloom for about 2 weeks, before things cleared up.
The colors Ive been able to pull out of these corals has been nothing but amazing. I was never able to get these colors with the 250s. Also there are no signs of slowed growth or bleaching by any of my SPS corals. And my Crocea clam loved the change.
