How this pool works

Sedge 20 pairs a 20 x 12 ft swimming zone with about 174 square feet of planted regeneration zone, roughly half the water surface. The swim zone is built as a sculpted gunite shell. A pump pulls water through a gravel and shale filter under the plants, where bacteria and roots strip out the nutrients algae would eat, then returns it clean over the rock cascade. No chlorine, no salt, and the water stays clear because something other than algae eats first.

Every number on this page comes from the same engine as the designer: the dig, liner, filter media, plumbing, pump, plants and finish work for this exact layout. Open it in the designer to fit it to your yard, or book a free 10-minute call to talk it through.
