[QUOTE=mr_X;1094866]when i had a normal sized refugium, i used this, with a 6500k, 23 watt bulb. it works great and was about 10 dollars total.
I went to home depot and couldn't really find anything around 6000k. They had a few pricey metal halide bulbs but you need certain ballasts for them. And I dont't think I'm going to buy a mh
buld just for my refugium.
So can just any high watt florescent bulb work?
