I had the settings at the third blue setting from bottom at the time and I think in the 50-65% range. The lights were sitting at 15” above water line. I have since lowered to 12” and I’m now at 93% at second blue setting. I changed to the more blue setting after reading your ap700 review. The parts that are not getting hit by light as much( lower branches) are still green in one particular acropora colony and my efflo colony is still basing out and still green. Nutrients were nitrate around 25-30 ppm and phosphates around 0.08 ppm range. They are now nitrate 5 ppm and phosphates 0.02-0.04.
