The 5 or 6 year old rubber pond liners are taking a beating.
I'm contemplating doing concrete. I've been reading on it, most of the time it's for a Coy fish pond. Sounds like typical thickness they are going is 4"...
So, thoughts? I don't think I'd need to go that thick, but, I'm no expert.

@huskihl ,
@Stihl working Hard , what are your guys thoughts?
I've also read that for fish, a guy has to spray it with a rubber coating otherwise the lime leaches out and kills the fish.. not sure if it's an issue for deer, birds, and such? I see concrete cattle water holding ponds.
