I have a 92 gallon corner with a 20 gallon long refugium. I bought the Eheim 1262 because of how quiet and good these pumps are but I was thinking about the head. At 4 foot it only pushes about 600 if that because I'm going to be putting a emperor 40w uv light on the in line as well. So what if I put two Eheim 1262 pumps with their own separate return lines so I can get somewhere between the 1000gph to 1200 gph I need for my 10x my tank.
