If the leak is on the bottom then bentonite clay is safe and might work.
Also if you find the leak on the edge there are liner patches that are
easily applied and that will work (I'm assuming though that your reference
is to something to pour into the water and have it seal up the hole... in
which case bentonite is the only thing I know of and it will only work where
it is going to settle - bottom) DK

BTW, there is no product that you can safely add to the pond's water to
seal
the leak. That works (somewhat) for pressurized tires or radiators, but
not
pond liners. That's too bad... it would certainly make life easier!!
Happy ponding,
