Cement Pond leaks

[Mo0]

So I have a around 300g cement pond that has a leak somewhere. What do you think is the best way to repair it? I was thinking just getting a rubber lining around the pond or should I patch it up? It is in the ground, doesn't really leak that bad, and has two Koi in it.
Thanks in advance.

I just ordered a thick blue liquid that comes with a syringe and you slowly inject in around where you think the concrete has a leak. Under the water of course. It comes with non-toxic adhesive strip that you stick to the cement under the water where the leak is.

The easiest repair would be to empty it, put in a rubber/EPDM liner, then refill it. That will stop any leaks.

If you don't want to do that, you could try hydraulic cement, sold at most home improvement stores. Drop the water level below where the leak is (if you can find it), then patch the crack/hole with hydraulic cement.

Hi,I agree with Conner,I had the same problem in the past and used other liquids to seal the leaks having no success,waisting time,money and work!

Alright thanks for the help.
I probably try to do the liner.

that wouldn't be a bad idea, going with the pond liner, seems like it would be easier to clean and all that. Plus then you can put rocks around the edge of it, make it look all fancy
