Ideas for LED supplementation

[Reefer Rob]

I had no color separation with the LEDs 16" - 18" off the water, or since I removed the optics to reduce the intensity (and moved them down to 6")... but then I don't have sand.

I agree there are some missing spectrums, especially red in my case. I get no algae in the display at all, and almost no slime on the glass. Likely this is also effecting the corals.

I'll let you know what I think after I've added a few of Milads OCW LEDs.
