I have a fish pond outside with a pond plastic liner sheet ... it is probably 12 or more years old and for the last 5 years or so I have used aquarium caulking to repair any holes and tears. It is actually time to replace the liner but seeing as we plan to move this year I want to make do for this summer. I used to get the caulking at Home Hardware in Souris but as of last year it is not available there any more. Would any one know where I could get a big tube at a reasonable price or have you tried something that might be better? There was a rock that fell in the pond and did extensive tearing so I cut out a dinner plate sized hole and each year patched it with new plastic and the caulking so it is a major repair. Each winter with the freezing the old patch comes loose and must be replace.  
TIA
