Building a sump/refugium
			 
			 
			
		
		
		
		I'll be getting some 1/4" thick acrylic this week, and was wondering what the tallest sump I could build with it, both with, and without cross supports along the top.  The sheets are 50"x75", and was thinking of making it a sump/refugium, that measured 18" tall, 24" wide, and 72" long, with each being half of the length, (so, a 36" long sump and a 36" long refugium).  Thanks in advance for your help. 
 
Regards, 
Robert 
 
P.S.  I don't know if it's cell cast or extruded, so, let's assume extruded, and go worst case.
