Drilling a tank.
			 
			 
			
		
		
		
		Hey everyone.  I have a 48" x 12" x 18" tank sitting empty in the house, and thought I would finally get it up and running.  How hard would it be to drill it for an overflow or two and a return?  I wanted to use a sump on this tank and it needs some prep.  Is this something I can do at home with the right tools?  Should I take it to a glass shop or tank maker to get it done?
