Thanks Kev135!
As a little update, the tank is looking incredible! It's nearing its 1 year anniversary, and things have really smoothed out. The corals continue to color and grow tremendously. John is doing a great job caring for this tank.
I recently got a PAR meter and we tested it out. I don't have a good full tank shot to map out the numbers for you, but in general, our lighting scheme is providing values of around 350 near the surface, high 200's near the middle, low 200's closer to the bottom, and low 100's at the substrate. Our 400W MH bulbs are getting a little old, and we've got plans to change to different bulbs relatively soon. Hopefully we'll have nice photos to post for the official 1-yr anniversary.
