Re: new pond gone wrong

oh. I see.
Concrete / cement around the edge of a pond should be well above the water level because it contains lime. Lime is toxic to fish. You can how ever "seal it" with something like G4 "pond paint" (Other brands of "pond paint" are available) G4 is also available in black. (Honest, its available in black or clear)
I presume your liner is black?

Good quality costs. Bear this in mind before you start.
Sorry if my reply is NOT want you want to hear, but what I have said is true.

We can only go by what you type.

A "thank you" costs nothing, but goes a long way.
