Liner for decorative ATO vessel

[JCATL]

I have a large urn I want to use as an ATO vessel, but I'd like to put a liner of some sort in it to prevent anything that might happen from the salt water being in contact with it. Is anyone aware of any large/thick bags that would work or some other material I can spray/paint onto the inside for extra protection?

Thanks!

ATO should be fresh water? A Heafty Bag is sturdy but ugly and would tend to get sucked into the pump intake.

Auto Water Change? Same issue with the bag. What material is the Vase made of?

Hah, yes fresh water… what was I thinking? Clearly I was not… So I think that answers it. There are no concerns with salt water affecting the interior of it. It’s fiberglass and the interior has been painted with what I would guess is either acrylic or some sort of plastic coating.
