New light / corals not happy

[Chris444]

Last week I have changed the light unit from some cheap unbranded to Viparspectra 300W LED. All the corals are doing fine except Green Mushroom and Torch. They have been ok on day 1 but it is just gwtting worse. They are shrinking and bleaching. I might have not acclimatised them properly to the new light.
What I can do in this situation to save them and make them happy again?
It must be the light thats the problem as all the parameters as in check and stable.

They were likely shocked by the light change. Best you can do now is turn the light down low and let them adjust. Once they start looking better you can slowly turn up the intensity.

Your corals have to get use to the new lights. Try cutting your bright time down and slowly build it up.
