What exactly are you doing with this pond? We remember the thread on
the stone work repairs. Is it for fish or plants?

Long story, the wife wanted to save some mosquito fish, so, we put them
there, and then I cannibalized the pump for the filtering system ... so
.... well ... so .... um ... well ... that's the end of the strategic
answer to 'what are you doing with this pond' question.

It's a multi-level structure, which, I guess, I should do *something*
with, but I never asked for it in the first place (it came with the
house).

What do other people do with these things?
How do you filter it without filtering the fish to death anyway?
