Anemones don't like UV?

[snowhite]

I have a 90g with 3 RBA, 2 GBA, and a few Rockflowers.
Every night I ramp up UV on my 2 AI Hydra 32's to about 30% the hour before bed for the glow of my corals and such.
I've noticed that all but 1 of the Anemones will shrink away or even move slightly under something for shade. The lights been like this fore more than a month... almost two.

Anyone noticed this tendency? 30% isn't much. Most lighting plans use much more than that.

It’s not that they don’t like UV, its just that they no longer detect daylight so the get ready for bed, so to speak.

My UV is cranked on max on my two hydra 32's so you should be good

Does UV directly increase any algae growth or anything else?
