Red Sea LED 90

[Liszt_1]

Does anyone recommend Red Sea LED 90?
I have the Red Sea 240 with four 90s.
Some of my coral was bleached then died. This just happened so I bought another set of these LEDs.
My former LEDs were great and all my coral were healthy and growing. I've had them since 2020
I have the Neptune system so my corals are fed.
What could be the problem?

Need a par meter to determine the answer to your question. RedSea LEDs are low par in my experience. I had better luck with an AI Prime 16 than that.

I have had great success with the 90. The power is in the Pur with these light that our par meters don’t measure very well. The higher you run these lights, the stronger the water flow and make sure nutrients are in line.
