BV,

Some of the pond books I've read say filtration and oxygenation (even in
small ponds, example 20 gal.) is not needed as long as very few and very
small fish are added.
Does your experience find this to be true? If the animal population is kept
very small compared to the pond size, can you dispense with filtration,
except maybe some plantlife?

I have heard of ponds that are with NO filter..any info folks?

If you have no fish, you don't need filtration. If you do have fish, it is
conceivable to have a filterless pond. Some ponds are fed by a spring, and
as such the water is always changing, so filtration is not needed.
