Hi

I've got two filters running into a 1600 gal pond. One is a pressurized UV
type at 5000 lts & the other is a 9000 lts biological box type. They work
fine but as ever I'm looking for better water clarity / quality.

I seem to remember reading somewhere that adding an air stone into the media
of a bio filter helps with the filtration of both solids and bacteria etc.

Can anyone shed any light on this?

Thanks

the bacteria that break everything down need oxygen. is the pump flow too fast for
the UV? do you have a place for solids to settle in the filter?
