on small ponds,

My flower pot filter only took one $8 19 gallon flower pot with no holes

Huh. A 19 gallon skippy filter cleans a 1000 gallon pond. Slick! So my
modest 220 gallon pond would be adequately served with a skippy filter
between 5 and 10 gallons in size. That's do-able.

My question now is, isn't the skippy filter a bio-filter, using bacteria
to remove nitrates/nitrites/ammonia? How does it do as a mechanical
filter? That is, does it also remove particulate matter, or do I need
something else for that?

John,
Who's at that dangerous stage of imagined understanding.
