The Look of a Water Garden Pond
But Much Safer for Raising Koi

Marlin Series Hybrid Pond


A Hybrid Pond™ is safer for koi than a water garden pond, but is more natural looking than a koi Pond in the landscape. A "hybrid" of the two, only made possible by the Patented Hydro Vortex™ backwashable Waterfall Filter. If you don't have a backwashable waterfall filter, a remote installation capable pond skimmer, a bottom drain, and a bottom drain pre-filter, a UV, or external aeration - you don't have a Hybrid Pond™. 

Marlin Series Hybrid Pond™ Kit Includes:

  • Marlin Hydro Vortex™ easy to clean backwashable waterfall filter with 20″ wide waterfalls, filter cleanout kit with 10′ of heavy duty black 1½” flexible PVC pipe, and 1½” stainless steel lever shut-off valve, 3.66 cubic feet of Hydro FilterSilk™ easy to clean filtration media with 1,354 SSA
  • HydroFlush™ backwash system with 1½” flex PVC pipe, 3-way diverter valve and 10" round valve box
  • Piper HydroClean™ Pond Skimmer with stainless steel and nylon leaf net, Black Knight Filter Brush Rack, 6″ inlet pipe, three 2” dual female threaded outlet ports, and one ½” auto water fill valve port. Remote installation capable and fish safe.

Our Exclusive Marlin Series Hybrid Pond™ Kits make Beautiful ponds
That are Part Water Garden Pond and Part Koi Pond

Marlin Series Hybrid Pond

For years there have been just two types of ponds - a water garden pond, or a koi pond. Many companies falsely market their water garden pond kits as koi pond kits online. Ask any prominent koi club member anywhere, and they will tell you that a water garden pond is in no way the same, or even similar to a koi pond. Find a local koi club in your community and ask them yourself by clicking this link:

Over the years, we have known several contractors that were sued by their customers because their customer wanted a koi pond, and then the contractor installed a water garden pond for them instead - to the customer's dissatisfaction. Koi ponds have smooth, bare liner bottoms with no gravel. Water garden pond bottoms are covered with gravel. A koi pond's structure is behind the liner. A water garden's structure is rock inside the liner.

This is what led John Russell, the CEO, Company Founder, and product design engineer of Russell Watergardens to invent the Hybrid Pond™ concept. With the Patented Hydro Vortex™ backwashable waterfall filter, also invented by John Russell, the Hybrid Pond™ concept became a reality. Koi ponds all had similar things in common, such as a backwashable biological filter, a bottom drain, a bottom drain pre-filter, a pond skimmer, UV system, external pump and aeration, with NO rocks or gravel in the pond. So it dawned on John to combine a water garden pond kit with a koi pond kit and the Hybrid Pond™ was created. Simple as that. A koi pond is the safest form of pond for raising and growing koi. A water garden pond is intended to look more natural than a koi pond in the landscape, but is not the best choice for raising and growing koi. The Hybrid™ Pond is the best of both worlds in one pond.
