I have a Giesman Aurora. I am sps dominate. I have been using 2 Blue + and 2 Coral Plus along with their 4 banks of leds in the Auraora (Cree lamps) that put out a total of 300 watt. (75 per bank) My par is low being only 240 at the top and 90 on sand. Tank is 24 inches deep. I have their whites and only 15 because if I raise much more the tank is very white. Lose that windex look. My corals are growing well being adjusted to lower par. However I would like to raise the par so I can grow more sps 250-350 par and more chalices and lower light sps in the middle. I would like a bluer look. If I raise the whites what could I change in tank to keep growth but bluer. Also Corals growing but not as vibrant colors as I would like. Fixture 8.5 inches off water.
Any thoughts?
