Really nice looking tank. I like how you laid out the corals, should look wonderful once it fills in. How high off the water are your radions? How deep is your tank. I have had my wide lenses on my garage shelf for a year now and always debate putting them in. I'm convinced I have some hot spots because I have certain areas in my tank that no coral survives and bleaches while other spots seem to be sweet spots where any coral placed there does amazing.
i use the RMS mounting kit from ecotech. my tank is 20'' deep. most of my SPS are mid-top section, about 10'' to 4'' from water.
