This is probably a silly question but: What do you use to draw-in water from your tank (not a sump or refugium) down tubing to an external pump. That water is then sent to a chiller which returns the water back up and connects to a wavy sea plus? I believe this is a type of "closed loop"? The tubing would be 1" to the eheim (about 900 gpm max.)
