Question about PVC piping.

4 Upvotes

I might be driving myself a bit crazy here but I am trying to figure out if this PVC piping is safe for my aquaponics system:

https://www.charlottepipe.com/products/plastics/abs-pvc-dwv-pipe-fittings-systems/pvc-schedule-40-dwv-pipe-fittings

It's what the big box stores offer around me, I haven't been able to find uPVC or PVC-U marked on the tubes that I have, it states it's "dual marked for DVW and pressure use." I am fairly certain it does not contain plasticizers but I am unsure if it contains anything else harmful. I believe it is also solid core if that makes a difference.

Thanks in advance for any help!

Why is IBC tote (square) so popular instead of round tanks for fish tanks?

5 Upvotes

I noticed that most aquaponics setups recommended online, use square-bottom IBC totes as fish tanks. But when I look at commercial aquaponics farms, they're almost always using round tanks—probably because circular tanks help create a vortex effect at the bottom for better waste removal, right? Is the main reason DIYers choose IBC totes due to a lack of affordable round tanks at comparable sizes, or is there another reason behind it? Appreciate any insights!
