OgreKV, I've got the G2 light...110W. What exactly is your lighting schedule? I'm thinking mine may be too long because I couldn't get the cyano to stop. I believe the blue turn on around 11a.m., white (don't have the 30W bulbs) turn on at noon, white off at 8p.m. and blue off at 9p.m. Last night I did replace the sand with a new bag of Hawaiian Black (and do a major water change) and put back only a few rocks, a couple softies and the fish and inverts. No cyano today...so I'm thinking it was partly the sand...it was from a sump and pretty dirty.
I need to move my Solana contents which does have SPS and a nice RBTA into the tank with the G2. They are currently under and LED fixture my hubby built that has a mixture of cree bulbs, 12 blue and 12 white bulbs at 3.7W's each. I'm thinking G2 will still do well for the corals as I have another RBTA in this tank recovering and it's coloring back up quickly. What are your thoughts? FYI...I got this light after I saw yours LOL...got in on a group buy for $400 including shipping.
Also do you use the mounting rack or did you suspend it and if so how high do you have it from the water? I don't know why, but I'm worried not suspending will put it too close to the corals and stress them out. I had a chalice on the side before, somewhat shaded and it started to bleach.
As far as my opinion on LED's...I really like the color. There is heat, but it's directed up. I actually have a heater on my Solana...usually stays about 78, but never goes above what the temp in the house is (80 when we are at work).
