I am helping a friend setup a 220 Gallon tank. He is ready to start pricing the lighting. The braces that run across the top of the tank split it into three sections. I thought that a 250Watt on each end and one 400Watt in the middle would be a good setup. I am curious what others think of this. Is it enough? Should we go with three 400watts? I think the tank is 30 inches deep.

He is going to use 4x65watts of PC actinic to supplement the MH.

I was looking at insidesun.com to buy them from. Has anyone else had any experience with this vendor? I had a local guy tell me he got all his lights from them and they were great.

What about these lights with 10k XM bulbs?

Any opinions would be appreciated. I use PC lights in my own setup and do not know alot about MH's.

Are the XM bulbs coated for UV or do they need a piece of UV glass in the fixture?

Thanks!
