Looking for suggestions. I am having a real problem with SPS. I lost all my one frag. All turned white...could be a seperate issue, but I want to get an optimal setting. Right now, I have the overall intensity of 50%. Whites max out at 38% for two or three hours. Blues are around 80%, red and green maybe 5-10%. UV 85%. My tank is 72x28x22. Lights are on an RMS mount across the tank. They are about 10" of the tank. I am currently running three of them. One of my lobos also started to bleach. The rock work goes (at the highest) to about 18" inside the tank. SPS are mounted around the height. LPS are mid to sandbed.
