I'm doing some plumbing and the tank is up and running I am curious how long does everyone let their pvc glue sit before using it in their aquariums. Can i use it within a couple hours or does it need to sit for a longer period of time
The directions on the bottle will tell you exactly but I have waited as short as 5 min to test and had no leaks. Temperatures are also a factor for cure time.
I set up my PVC and had it running when i glued my stuff together.
I glued the exterior not the interior of the PVC.
I used the purple one (I think it was like 5 min to dry but was faster as it was not thick) and I mainly use Red Acrylic Cement glue (I think its #5 or something like that).
Put it on, press your finger around the PVC so the glue is in the cracks and dont drop any in the tank water (dont know what will happen if you do so I avoided it )
