montipora turning brown - help

[Jcearl]

i previously had reef radiance DM-120's just got reef radiance starfire's, my red cap monti started turning brown almost immediately my green slimer turned white within 1 day.. i turned the whites down and after a week i noticed the browning is spreading slowly and so i turned down the blues on my previous 120's i had the whites and the blues at 100%. now they are both at 30%. any help ideas etc..?

I would just leave it low like 30% or lower and give them time. Watch close. I've had them turn white but not brown. Hopefully they recover that's a beautiful peice you've got there

so nothing else changed? Only the lighting. If so, then start it off at a low setting. At times like this, it's great to have a par meter to measure what it was at before so that you can set it the same for this new light.

A lux meter is a good an less expensive tool to measure intensity as well. Not the app btw please.
One turning white and one turning brown though is really weird. As I understand it they would be for browning not enough light and the other too much. Browning is usually slow.
Unless the one of the new spectrums introduced was too intense and both expelled their zoo ox but I the monti it left brown as thtt is the color of the flesh without it. The slimer only had one color and it left it white.
