Radium bleaching?

[Doug]

Thanks Stephane,
Your corals were use to a fair bit of light though. It shows, as does Brads, that you guys are running them on HQI, which burns them brighter than mine.

Thus, the idea that mine bleached because they were to much, seems a bit far fetched. The pink monti came from under several vho bulbs and 250w Radium bulbs, however it bleached in a week in my tank.

Which ever it is, I lowered the bulbs today, oriented them different and added two fixtures running 4-40w 65K Ultra normal output bulbs.
