Light change / corals

[Chris444]

Hi, 3 days ago I have changed the light unit, all corals seem to be happy apart from torch and mushroom. They torch is not opening at all, the mushroom seems to be a lot smaller and it is white in the middle as it was never before.
I have the light on a low settings. Is it normal acclimatisation or theres something bad happening, I am more concerned about the white colour on mushroom. I rather to ask and fix the problem before its too late.

Torches going through light shock more than 3 days would make me a little worrisome. If it still ends up irritated tomorrow and not showing improvement i would move it to lower light with the same flow. It can be hard to get torch back happy again after a certain point and the usually go down hill fast or just unhappy and slowly fade away. Wish you the best tho! Mushroom looks fine. should be alright. it seems easier to shock corals bringing them up from lower light most of the time. raising 5% intensity to 10% intensity is a 100% increase where as if your lights were at 80% intensity and you raised it 5% it would have much less of an impact on your coral
