It’s not like people on here don’t hoard stuff like that.Yes, that is a bit of a worry.
Main concerns:
1) Leaking.
But this short term, and I can be careful.
2) Algae and Mold inhibitors in the PVC.
I doubt cheap ones will bother. Plus I am not using it for coral, so should be ok for fish.
But the alternative is some big stock tank, which I then have to get rid of later.
I guess I could ask around though.
