Did you experience any initial polyp retraction, bleaching or color shifting with the new 400 watts MH's?
Those purple polyps are known for browning out under intense lighting is why I asked above.

PS. I've only known 2 people who have ever ran 400's with zoas and plays. The coloration is/was stunning to say the least, but height of placement was vital.
