Oxygen for the Koi Pond is provided by a HydroAir™ aeration system, and the water is pumped with external Hydro Centrimax centrifugal pumps. No high voltage electrical devices are in the water.
Koi Ponds are not considered "landscape features" like water garden ponds, or Hybrid Ponds™. Instead, the Koi Pond is a more "formal" structure within the landscape like a swimming pool. Koi Ponds can be built completely underground like water garden ponds or Hybrid Ponds™, or, they can be made partially under ground, and partially above ground. The Koi Pond is constructed with either concrete, concrete blocks, or timbers retaining the earth "outside" the pond and have rubber liner, concrete, or poly urea liner holding the water "inside" the pond.

Maintenance of Koi Ponds is very easy. Simply backwash the HydroBead Vortex™ filter at least every 30 days, rinse the HydroClean™ pond skimmer elements at least every 7 days, and empty the Hydro Centrimax™ leaf trap when debris is visually seen through the clear leaf trap lid.
Maintaining a Russell Watergardens' Koi Pond takes just a few minutes each week.
A Koi Pond without waterfalls is a quiet, peaceful pond with beautiful Koi gliding about in blissful silence. All the oxygen in the Koi Pond is supplied by the Aeration Towers™ that pass 100% of the pond water past HydroAir™ Stones inside the plumbing system as to not disturb the surface of the pond for maximum viewing of the Koi. The pond can be lit at night with underwater lighting so the pond owner can view the beautiful Koi at night.
The Bottom Drain, HydroSeive™, and pond skimmer constantly remove waste and debris from the pond, so the pond doesn't have to be drained.
Nitrates get removed from the water during the backwash cycles. As pond water is used to clean and rinse the HydroBead™ Vortex filters, new water is replaced in the pond by an automatic water fill valve inside the HydroClean™ pond skimmer.
