Help

hey I posted this in the reef section but no help has arrived yet so
I will post here and see if I can get some here.
I did a DIY refugium last night and well I used PVC to create a spray bar and I used primer and glue for PVC but some of it trickled out of the seams and ran down the side of the spraybar is this ok or should I scrape the PVC with a razor to remove the primer? Am I worried about nothing? I do not want to put this thing up and running and kill my fish if the primer is deadly.
Also will a rio 2100 be enough turn over to send the water back to the display it has to travel 3.9 ft all connections are 45 degree angles to allow for smoth flow. Thanks a million
