crab in eye of chalice

[Proteus]

I had issues with LEDs and it did include browning out Sps. I'm still waiting for color to come back. I have some pieces that bleached and some that browned. I started with Mh and then switched to led. The issue isn't with how bright but the amount of usable light. Mh usually have about 70% useable light while t5 and led can be 100% usable.

Being said how are water perameters. Even nutrient that u don't test for can affect the coral. High iron will bring out greens for example
