Like the sun I tell ya', like the sun.
I just installed my new light. If anyone wants to come see it you are welcome to, but for liability reasons you will have to either wear sunscreen or sign a waver. My 30 gal now has two 150 watt hqi bulbs (20K XM). It looks good. Maybe not great but good. I'm thinking of adding some blue compacts, but it is good enough.
So if anyone else is thinking of setting up a 30 gal, you can get buy with 2 small halides. Just so you know.
