Filter Sock Question
			 
			 
			
		
		
		
		Just wondering if anyone here uses filter socks in their sump.  I had started using them, changing it every 3 to 4 days with a clean one, but know I’m wondering if I really need one.  I’ve read some info about the sock adding nitrate to the water if your not careful and replace the sock often with a clean.  
 
Do you use a filter sock ?
