Want to make the best possible chances for this pond not to leak the first time. It is going to house rays and will be around 8ftX5ft and maybe 2 ft deep, possibly 30". What type of and/or thickness of liner should i go with...? Thanks Mike
My uncle uses pvc liner and it is about 46mil I believe. I believe that that is that same stuff that Colin (rvrrays) uses for his ray pond. You should try giving him a PM.
