skimming

Randy, your wrote in your skimming article:

"Drops of water in air (which may, in fact, occur in portions of some skimmer designs), or even a rapidly turned over flat surface could be just as effective"


I was thinking how would you collect organics by spraying drops of water into air? And how does rapidly turned over flat surface collect organics? Or is this about bubble production?

What does this imply?

Thanks, Box :)

Downdraft skimmers first make droplets of water in air, then they hit the bottom and become bubbles in bulk water.

[B]And how does rapidly turned over flat surface collect organics?[?B]

An overflow collector on an aquarium does this quite well, since organics readily collect on the water surface, but you'd have to send it into a device (like an ordinary skimmer) to separate the organics from the water.
