Refugium set up

[noo2usa]

I just finished setting up a small refugium for my 120g. I used sponge for dividers and threw some cheato in and plugged in a metal light reflector with a 6500k, 13w flourescent light bulb. So far so good I think. Any advice on anything else I can do?:neutral:

What size is the fuge area? Also is the bulb enclosed or an open spiral?

Area is about 18x12 about 8" deep. And the bulb is an open spiral.

Open spiral can shatter if wet. I would Look for an r40 cfl. That way it's enclosed. Also up the wattage. 5k color range is optimal.
Mine is 14x13 with a 23w r40 5k. Equivalent to a 120w bulb. Home depot carries them.

Daylight color home depot bulb is 5100k
