Question. PVC or Vinyl Tubing?

[KBlue]

I’m curious to know peoples thoughts and suggestion on whether or not to use rigid PVC or reinforced vinyl tubing for overflow and returned plumbing.

There's also flexible pvc, which I prefer

Plus one on the flex PVC. Use a blow dryer or the likes to straighten it out if needed.

I've read the flex is better for right after the return pump because it makes maintenance a lot easier. Otherwise I think I'd do rigid for the overflow and for connecting to the bulkheads just because I would trust it more, and I think it would look cleaner.

Flex PVC.

It’s about the only thing in reefing / tropical saltwater that’s cheap, fast and easy.

PVC. UV and salt water tend to make vinyl brittle. no longer flexible at the very least. I personally like hard pipe PVC because it is dark in there and won't grow algae and i like the clean look of hardpipe. but for flex after the return pump for vibration absorption i prefer silicon. It stays flexible and doesn't stink like harbor freight.

I use black vinyl hose.
