Corals becoming pastel color?

[kien]

Some people strive for those pastelly colours in their SPS. Typically people will achieve this by starving their corals. Try feeding them more. An over abundance of light can cause them to lighten up and slowly bleach out as well.

Are you running an sort of probiotics on your system? BioPellets, zeoVit, prodibio, vodka/sugar/vinegar? All of those can starve your corals.
