What exactly is a "bucket" filter? Do you just put a bucket with filter
material in the pond, or is there a pump attached to it?

As RM explained. Only Solo mentioned using polyester batting in hers so she
could just toss it when it clogged up.

I have used DIY bucket filters using open cell foam cut to fit the bucket
with a hole thru it for the tubing/pipe. One can also do a trickle filter
by putting the pump in the pond/Q-tank and running the hose up to a bucket
off to the side or over the pond (so the water flows back in from the
bottom). The bottom must be very slotted, so the water doesn't build up in
the bucket but actually flows straight thru. Media for this can be anything
from lava rock to special ceramic pieces. Supposedly trickle filters mature
faster than submerged ones with the added plus of getting rid of nitrates.
They are not for removing solids.

I personally have never used one, and with plants in the pond (or filter)
nitrates are not a problem either. ~ jan
