Over the course of the past few months all of my sps are turning green, or having a greenish tinge to them.

Water chemistry is on par and i'm seeing good growth. They are under 2 AI Hydra 26HD running a AB+ spectrum posted on this forum and verified in BRS's video on replicating AB+ spectrum on AI lights.

I have turned the intensity down a bit from recommended settings as I thought they might be a little strong for my setup.

Tank Information

36 X 20 X 21
Lights mounted 9.5 above WL

Water params:

77-78 stable
1.026 stable
9DKH stable
440 Cal
1500 MG
Nitrate: 4-5
Phosphate: .02-.04

Thoughts?

Tell you the truth I tried that spectrum also and didn’t like the coloring I was getting. Since going back to Saxby with a little tweaking of my own I’m getting better coloration again.

From the BRS settings, I took the intensity down around 40-50%. Scorched coral before with these lights so played it safe. Things were growing and doing well so I left them as is.

I would use the acclimation mode and bring the intensity up to the BRS levels. My guess is that you don't have enough light.

@Bulk Reef Supply rents par meters. I would suggest getting renting one. I was surprised at how low my par was when running just the Hydra 26HD with the AB+ program.
