return pump not performing
I got a used red dragon off a fellow reefer - 4.5m3 model (1200 gph) this thing isn't pushing even has hard as my Sedra 7000 (700 gph)
I've taken it apart and cleaned it, what could be the problem?
outlet is restricted to 3/4" lines rather than the 1"
inlet is a 90 degree elbow (proper size) - I've seen some diagrams for other red dragon pumps requiring a long straight tube as an inlet.
any thoughts on this would be appriciated
