			 Have decided to set up a room of tanks dedicated solely for frags and need a little help with the layout.There will be 2 possably 3 racks with 4 tanks on each rack.I was thinking of running either NO or VHO(24 inch bulbs).If I was to run 3 over each tank,would I need a ballasts for each tank or could I use fewer ballasts(just bigger).I'm just trying to wrap my mind around the idea of how things should be set up. 
		
	
		
		
		
		
			The frag tanks would be mostly zoos,rics and other softies.

			 I am thinking of doing somethign similar.  I was looking at 48" NO, 1 actinic and 1 10K over each, just using regular T12 fixtures.

			 Are you making these tanks a custom size or anything Jim?  You might be able to get away with even N.O. lights if the tanks are shallow enough.  Or you could get about 3 or 4 WH8 ballasts and run 2VHO bulbs/tank.

			 I would like to have them made  shallow if I could find a place locally to make them.Have them all drilled and maybe do some kind of closed loop for each rack of tanks with an in-line filter system?(not sure if that would work or not)

			 That's what I would do as well.  Get some 24x18x9 tanks made up.  4 stacked on top of each other, each tank draining into the tank below it and finally into a common sump where you can put your filter socks, heaters, UV, whatever and all run on one pump (like a Mag 18 depending on height of the rack).

			 If I can find a place that would do all the tanks I need for a fair price,I would definitly go acrylic(easier to drill)
