The Aquascape Recreational Pond Kit 9' x 20' comes complete with everything you need to build a beautiful recreation pond with a 9' x 20' deep water zone, a 5' x 6' intake bay skimmer, and a 7.5' x 11' wetland filter. By bundling the perfect selection of products, this kit eliminates the guesswork and calculations required when purchasing components individually. A powerful ExT 12000 Pond Pump is included to pump water through the intake bay skimmer, waterfall(s), wetland filter, and water circulation jets. The intake bay draws water in, creating a skimming effect to remove debris from the surface of the water. The pre-filtered water is then pumped through the wetland filter where smaller sediments (suspended solids) are effectively removed, and biological filtration takes place to improve the water quality and clarity naturally.
