Seagrass Kelvin Rating?

[ThePurple12]

Currently I'm using 6,500k metal halide bulbs. They're great for seagrass, but they make all my corals look brown.

I want to switch to something between 10,000k and 15,000k. Of course, the higher the color temperature, the better-looking the corals will be, but will my seagrass be okay in a higher color temperature?

IMHO even a 10,000K or 15,000K bulb will have more than enough mid-range spectrum for you sea grass. It's not like the bulb only emits one spectrum. It's still mostly white light, just a bit more blue.

On a different note, I'd love to see a photo of your tank. I'm just starting to collect a few small bits of what I call sea grass (with some roots) when I do beach walks and estuary walks along the SW coast of Florida.
