We have just had all out big trees lopped and in doing so a branch must have pierced the liner. I think that the water level has dropped as far as it going to which indicates that the leak is in the side. I have some spare liner but need to know the best glue to use to stick the patch in place. I have some Bostic professional glue which has worked fine on pond liner to make tomato rings but I am unsure as to if it will be OK under water.
Any suggestions please.
