Filtering Waterfalls & Weirs
|
Filtering Biological Waterfalls
· Water fills the filter, rises through filter media, spills out into the pond or stream
· Floating sediment settles into the bottom of the fitler.
· Beneficial bacteria grows in the interstitial spaces of the filter media
· Clean, healthy water spills from the waterfall filter into the pond or stream
|
|
|
Waterfall Weirs & Spillways
· Creates a shimmering curtain of water spilling into ponds or streams
· Aesthetically pleasing sights and sounds of crashing water
· May provide some filtration; varies by manufacturer and model
