light required by diferent corals

[reefburnaby]

Hi,

So...corals adapt. I have notice that some of my corals just sit there and don't grow for 6 months to a year when I acquire them from the LFS. I figure that they are adapting to my tank. Once they adapt...they grow like a weed.

In general, our lighting systems have difficulty meeting the lower requirements for 100 to 150 uMol/(m^2*s)....let alone 500 uMol(m^2*s). In general, 0.01 to 0.02 uMol/(m^2 * s) per lux of light (depends on the light spectrum). IMHO, this measure is much better than the standard watts per gallon.

Also, you'll notice that certain corals grow in certain areas of the reefs. Based on the depth at which they are usually collected, you can get a rough estimate on the lighting and circulation requirements.
