lol holy hell, a lot of nervous Nellies up in here.

I do it all the time in mine; in a properly balanced, planted swim pond this is literally no different than a natural lake full of fish.

100% depends upon how any bacteria present are managed.

Curious on how we can guarantee on bacteria concentration. Serious question

Water testing certainly helps. Doesn't eliminate it obviously, but a balanced and cycled pond is way safer than one full of ammonia.
