PVC Glue, Medium or Heavy?

[dreamcatcherr9]

Which PVC glue is better for our aquarium use?
Medium or Heavy clear PVC glue?
Standard clear Primer?
And do you prime and glue both PVC and fittings (not just prime both and then only glue on PVC)?

I use std clear primer and std clear pvc cement. I guess that would be medium. Here we only have fast, medium and slow setting. You want to coat both surfaces. Then press together with a slight twist. The primer pre-softens the pcv a bit.

Thank you. For a specific brand (Oatey) there is a medium and a heavy.

Any suggestions or options anyone else?

clear primer and medium clear glue, helps keep your plumbing job nice looking.
wipe the excess off with a rag after each joint is set.

So medium would suffice? Or heavy not recommended?

medium will glue pvc so well, you will never pull the joints apart once it is set.
don't forget that little twist at the end.
