Anyone use this before? I am going to be adding a bubble trap to my sump and it will require the sump to be drained, panels set /siliconed in and cure time. I am sure this is partially wishful thinking but a few of the aquarium silicone products say it sets in a few hours but takes 24hrs to cure. I am really wanting this to mean that I can return the flow to the sump after 2-4 hours and the rest will cure underwater. Anyone have any experience with selsil or the others?
