I'm curious to hear what other people are doing to keep vibrant colors in their pastel polyps, particularly pink. I've got both the Pink and Golds and Hawaiian Ding Dang PE, as well as a few other pink polyps, and I'm having the hardest time keeping the pink in them.
I originally had a coralife Phoenix 14K 250w MH w/ two 65w PCs and recently switched to a six bulb TEK t5 fixture. Under the 250w MH, the Pink and Golds originally kind of faded out totally, and now have come back with vibrant gold centers, but very little pink edging. The DDPE the first time under 250w MH, bottom, then middle of the tank turned dark - greenish to black. The second time, under t5s they look almost bleached, but not quite.
My tank falls in the normal range for parameters, temp runs around 80*, I have higher flow (2 K2s, 2K1s, and a QuietOne 4000 as the return pump on a 65gal tank).
So I would like to see a discussion regarding parameters, flow, lighting, temp, or anything else that you can think of that you have noticed having an impact on keeping the pastel colors (particularly pink) in polyps.
