I was thinking of changing

[NHMickey]

one of my water falls and was going to replace the plastic one with a more natural one made with stone and rubber.... The question I have is there a certain rubber I need to use or can I use any type?

I know nothing about this but heavy duty plastic sheeting would do the job also.

A PVC Black Pool Liner. Do not use synthetic liners they can be toxic to fish. You can order the liners on line or try some of the garden centers some carry liners for ponds.

There is a water garden supply nursery in Whitman, Ma.

I tried heavy plastic sheeting before... Very hard to mold. I never thought of pool liner... I was also thinking I could try rubber roofing material... I don't have fish in the ponds as they are not deep enough for winter. But that may change as the place I get my plants will allow me to bring the fish back in the winter (have to buy them again in the spring but that is better than killing them)... Thank you for the ideas.
