there are some online dealers that sell it in black. White can cause algae growth, or you can just paint it.
From a poster on another site concerning eggcrate,
"I'd forgotten about this, several years ago someone at ORA, I think, was complaining about eggcrate causing algae outbreaks, and I laughed because I'd never had that problem, but about six months ago I I set up a 20L frag tank, that was connected to two other tanks, and this nasty snot-like algae or dino or whatever kept growing all over every thing in the tank. The eggcrate was new, while all my other eggcrate was years older. I only got rid of it when I removed the eggcrate and moved my jetties 10 gallon into the 20L. That damn piece of eggcrate is cursed. Funny too, that bleaching it didn't seem to help. On second thought, the ORA guy did some research and found that the chemicals used to help release the eggcrate from the mold leached phosphate, so the damn stuff could have leached for a long time. Vinegar could help wash it out faster."
