So I am taking out all of the vinyl tubing on my 600 gallon and hard lining the whole system. My problem is that the plumber that is helping me do this says that his glue for the pvc takes a while to set and then needs to be flushed to insure there is no contaminents left in the pvc. So this will definately not work. So I told him that I would ask if you guys knew or have used any other quick setting aquarium safe glue I can use to seel the pvc.

i do that all the time
