Yeah.. 2 or 4 bulbs would probably work best. Doesn't matter what amp the ballasts are, except on the electric bill.

Radiums are the only bulbs I run now. Great look and packs a punch. Yeah.. I'd wanna keep it down to two pumps as well. Maybe just steal a little from each pump to feed the tank. Or 1 pump is for skimmer and 1 surge and the other is for tank and 1 surge. I don't know.. There's a million options.
I got the tank off the stand tonight and a crew set up for tomorrow. If everyone is able to show and we get it out of my basement, Tuesday pick up is looking very realistic.
Talk to ya soon.
