water height in overflow box
			 
			 
			
		
		
		
		Just a quick question.. what determines the height of the water in the overflow box? 
 
If I do a herbie style overflow, matching the overflow with the return,  would the height ever get beyond the overflow hole? 
 
I am a bit confused because I do not know how high I need to make my box, or how small I can make it.  Any suggestions out there?
