Micron/polishing filter for ponds
Is there a micron/polishing filter for ponds? I had one for my aquarium
but I would not think it would work for a pond. I had a magnum 350 for
my 55 gallon and it did clear the water quick but the filter had to be
changed weekly and very expensive. So can I polish my 300 gallon pond?
And Ideas? Thank you
