Ok guys so here is my dilemma, I am running a 120 tank w/ a 30gal sump. I got a sweet deal on the Diablo DC 3500 , pump.works fine only issue is the previous owner glued some 1inch PVC to the outlet and it. Can't be removed. Space in cabinet is very tight so I was.going to use tubing for the return. With the 1 inch PVC glued to the pump, I. Ant remove it and use the barbed adapter that came with the pump for hose use. Is there tubing available that I can slide right over the 1 inch PVC? Or does anybody have another idea for me.
