Corals dying or bleaching out?

[Buklau]

I have put three new sps pieces in my 90 gal reef tank. They keep dying or bleaching out. I have radion led lights. So that's why I think they are bleaching out, then dying.
Water is great!

Phos .04

Nitrites 0

All of my other sps corals are doing fine, but I acclimated them to the lights when I switched over. Do I need to lower light power every time I put in a new piece of coral?

Any help? Thanks

They probably need light acclimated. A longer and slower drip acclimation may also be needed. All depending on the lighting and water parameters of the tank they were previously in. How high do you have the radions cranked?

What are your radions set at? Mine are currently at 65% power and it is still so strong that I have trouble keeping lps in my sandbed.

Maybe that's my problem. I have them at 95%. So I guess I will lower the % and see what happens. With your lights at 65%, how long are your lights on for?

They are on for 10 hours and only 1 hour at 65%. I think I'll adjust it down again tomorrow to make peak at 60.

Probably the issue. Very easy to fry corals with leds if your not careful. Most people run the radions at 75% or lower. Deeper the tank obviously the more power you need.
