sump life questions

[Lampshade]

Use a regular light bulb spectrum for your sump light, 6500K is considered daylight color by most company's, anything around that will work great. I use pellets and have very good growth from my algae's, I used to run my output of my reactor through my refugium since it needs to be oxygenated, now it's more convienient to use my skimmer. WOrks great, you'll have no problems. My only suggestion would be to use cheato instead of Caulerpa since Caulerpa can go sexual and makes your tank a mess when it decides it needs more room.
