What temp power compacts... or does it not even matter

apexkeeper · 09/19/2014, 12:26 AM

I have a 36" coralife aqua light pro fixture (150 watt metal halide and 2x65 watt power compacts) yea its old school but it works good for my tank... anyway I need to replace the power compacts and am wondering what to replace them with. They are currently 420nm, whatever that is...

With the halide off they are a really deep blue color and they do make my corals really pop, but with the halide on they are basically useless. Just wondering if a different temperature will have any effect on coral color, coral growth... anything.... marine depot has a few options... 6700k, 10,000k, 460nm, 420nm, and mixes.

any input?
