Best method to set your lights would be with apar meter

What's apar meter

[WillBattle]

He ment a par meter, it is used to measure the strength of your lights at different depths of your tank. However, with this tank being a week old, it quite likely has to do with that

I would test for Ammonia / nitrites / nitrates and see where you are at on those, you might be going through a cycle from when you transfered everything from the 14 gal biocube to this tank.

I'll do that this weekend with sometime off. But
What is the cost effective way without the par meter
Like eyeball or guess estimate. Or from your experience with led

[WillBattle]

Honestly the corals you are talking about ( zoas xenia mushrooms) really don't require high amounts of light, so unless its getting too much light, which from the picture it doesn't look like it ( too me at least ) I would look elsewhere for the problem, I do not think it is the lights

I know it's the water for now but I never have luck with led since switching to it over a year ago. It s not bloommy like normal reef tank

Sounds like a combination of both water first and foremost. Keep in mind that LEDS are far more intense it takes less lighting I would do what Binford suggested and raise the lighting and give it some time

I think once you take care of your water quality you will see your corals get happy again. I've got a similar diy led fixture on my tank and have been running it since last summer. I keep softies and they are jamming under LEDs. I would never go back to halides now. Check out my tank here. I run the blues at 70% and the whites at 30%. The light is about a foot off the water surface.
