Question - what height are people running theirs at over the water surface?

We run ours @ 14.5" above the surface but I doubt that is the recommended height.

Oh wow.

The reason I ask is I'm running mine at 6" above the surface, but after 2 months with them, I'm starting to notice colour loss in a lot of SPS (getting way more pastel-ish in colour - polyps have colour but white in between the polyps). Am I running mine too low? I put in 3 Mitras, each replacing a 400W Radiums on lumenarc reflectors.

I would just dial back the overall intensity. There is no reason to move them up unless you want more light spread.

I'm running my around 12" off the water surface, but I'm also trying to determine if the LEDs are what is causing my SPS to constantly die. So I've raised them up and dial them down in overall intensity.
