I have a Sedra pump powering two reactors in the sump, which is kind of silly since I have a Barracuda return pump that is only using about 70% capacity. I want to "T" off one of the return lines to feed the reactors.
My question is: How long should I allow the Weld-On P-70 primer and PVC 795 to dry before going back on-line? The can says 30 minutes cure time, but I don't trust that to a tank full of fish and corals. Anybody had any experience using Weld-On on a running tank? 24 hours or less/more?
