Curing time on pvc cement

[Fishko]

Im going to be changing my plumbing soon when i move my tank to a new stand. I have unions but plan on cutting them off because i cant find the correct smaller end that fits on the existing one. i can wait overnight for the cement to fully cure, whats the shortest time i can wait before running water through it where it would wouldnt affect my water chemistry. I would be running carbon. ive read people have done an hour, others did 20 mins. Max i could wait is maybe an hour and half. I would be gluing only two pieces.

20 minutes would be fine, I usually don't even wait that long. Wipe off any excess.

I wait like 5. so 20 is more than enough

Usually 15 mins for me but I know a lot of people that just run water right away.
