Messner 168/002393 Pond Skimmer 140/30 m² Water Surface

Simple product, reasonably priced. It does not float, which allows it to be positioned at a level above which water is drained from my pond by gravity. If it floated it would be always above the water level and never skim, or it would drain the pond at an uncontrolled rate - it is ideal for my application which would be supplying a gravity fed filter.

Too small. Does not float, so difficult to position
