A Ponder-ing Newbie
I have a strange question.
Is there some reason a reverse osmosis (aka: undergravel) filter is never employed in a pond?
Perhaps something like a heavy duty plastic grate suspended 2 inches off the bottom of a pond that has a good main drain... then covered with larger rock pebbles. This would look good, be great for biological filtration, and be within reasonable cost.
I am imagining the 1/4 - 1/2 inch grid plastic grating panels that go over industrial lighting in drop panel ceilings or such. Just put little rubber capped bottom legs on them. Then get large smooth river rock pebbles. The kind used for landscaping.
Am I crazy here?
