LPS corals lost fluorescence

[alaskaayers]

I was wondering if anyone knows why or how LPS corals lose their vibrance of color? I have two LPS in my 75 gallon reef tank and both have assumed a similar coloration of purple without the appealing fluorescent centers. One of the species is Platygyra while the other is an unknown brain. My tank went through a move recently and the corals didn't take it very well. I have restabilized and everything is thriving. I have a calcium reactor with Ca at around 470 and Alk. around 5 dKH. The corals are definately growing and happy just not as colorful as they used to be and I'd like to work to correct that if I could. Any ideas would be appreciated. Thanks.

Growth and color are sometimes independent of each other. I've noted when I feed phyto and cyclopeeze, the color improves: unproven that the LPS eat phyto, though perhaps they do; but they eat the critters that eat phyto, so that helps. Check your bulbs' age.
And corals react negatively to ANY change: they're just that way. They'll take a while to reestablish after the move: mine are in the same holding-pattern---happy, but not growing, also after a move.
