I use polyester batting when I want to get rid of stuff fast. It is great
for catching clay and algae and other "fines" in the pond. It is almost
impossible to clean up so I get big chunks of this at the fabric store, cant
remember the name of the brand but it has no additives. I put this in and
overnight it pulled most of the algae out of the pond. my bucket filter
isnt a trickle filter because it is in the pond. Here is picture of very
small bucket filter for tank or stock tank.

below that is set up for trickle filter.
gravel sets up very very fast as a trickle filter. It is the available
oxygen that does it. Ingrid

mentioned using polyester batting in hers so she could just toss it when it
clogged up.

Supposedly trickle filters mature faster than submerged ones with the added
plus of getting rid of nitrates.
