KarenM Posted June 28, 2007 Share Posted June 28, 2007 Got my lights in the other day (PC, dual 65W, dual actinics) and bought my first corl - a 6" piece of rock covered in green star polyps. They didn't look bright green at the store, but they were green. But when I put them in my tank, they look brown. My tank is 24" tall, and the lights are about 3" above the tank. I put the GSP on the bottom of the tank., so they're about 2' from the lights. I leave the lights on about 10 hours per day. Should I move them closer to the lights?

GKarshens Posted June 28, 2007 Share Posted June 28, 2007 More likely the problem is you don't have as much actinic light as the store did. Most stores keep there corals under very blue light to make the colors "pop" more. Quote Link to comment Share on other sites More sharing options...

Most stores keep there corals under very blue light to make the colors "pop" more. I think you're right on that. When I turn off the white lights and just burn the actinics, it's very green. Is there anyway to "green it up" a bit? Quote Link to comment Share on other sites More sharing options...
