This may sound dumb, but research here and at Neptunes forums hasn't yielded anything 
Even the instructions manual is no help. The instructions allude to PVC but nothing fits! 11/4" is mentioned but that size PVC does not fit!
Settung up a COR 15 pump and I don't know what kind of line to use. The return nozzle retention nut isn't sized for standard PVC, or 1" flexible nylon tubing I thought was it. Local store only has up to 3/4 Pex. Bulk reef supply is closed for the day.
Please help!
