I have recently moved in to a new house and have inherited a pond 8ft x

The pond is constructed of cement/brick and I have noticed that the

obviously a leak.

You can patch with any number of cements
or expoxies which work when wet.

Hydrolic cement can work when wet, but is that safe for the fish?
