They dissolve over time. You need to replace them every few weeks.

Daniel,
I can't help you on most of this, but for the mosquitos, have you
considered
a mosquito dunk? I've used them in my koi pond with no apparent ill
effects
on the fish or plants, and others on this board have posted messages that
they are safe.

Yup, I had a mosquito dunk in there. I don't know where it is now.
It rained recently, so maybe it dissolved or is on the bottom
somewhere. I think I saw a fish eat some specks of it--he's still
alive today.
