			 What siz and brand of pump do you need for a 300 gallon if you were gonna go with a closed loop system instead of powerheads? 
		
	
		
		
		
		
			6 outlets. 1 intake.

			 Im using a Sicce 4200 series. I guess it all depends on what your inlets and outlets are sized as, as well as what do you want to achieve with your closed loop?
