Corals becoming pastel color?
I've noticed over the last month my corals have started turning a pastel version of their colors.
what would cause this?
calcium is a 430
alk is 8dkh
magnesium is about 1300
phosphates .02 (basically where they've always been)
nitrates: undetectable.
seems to be happening to all kinds of corals (sps, lps, zoas) and colors (reds, blues, purples)
only green seems to be maintaing color
