This model was previously the Classic Aquadyne 2.2BHE

The Model AD8000HE - Model 2.2BHE filtration system includes a 2" High Efficiency Control Head with 2" plumbing in/out. This is the same control head and column as used in the Model 16000. The only difference is that the column is shorter in length, while maintaining the flow efficiency of the 16000. This additional efficiency allows an improvement in water flow by about 15% - 20% with low head, high efficiency pumps. 

As with the standard 8000 this model includes the Dynamax air assisted backwash which makes this model extremely efficient in all ranges of waste loading. This unit will efficiently filter 8000 gallons of water with up to 165 pounds of fish or other aquatic inhabitants. Even under the heaviest of waste loading, the Dynamax will break up a loaded media bed with ease. The larger media bed is very forgiving of neglect. You can backwash the Model 8000HE with as little as 50 gallons of water. In an 8000 gallon pond you will hardly even notice a water loss.

• Supports up to 165 pounds of fish.
• 2.2 Cubic feet of bead media (80 lbs)
• Dimensions: 24"D x 46", maximum pressure 50 psi.
• Average water to backwash 50 gallons.

The AD16000 is capable of consuming large amounts of fish waste and neutralizing equally large amounts of ammonia and nitrite from the aquatic environment. The model 16,000 will support up to 330 pounds of fish or other aquatic life in up to 16,000 gallons of water, separating and backwashing huge amounts of solid particulate waste without clogging. 

The Dynamax air assisted backwash makes this model extremely efficient in all ranges of waste loading. The high efficiency central diffuser column allows an efficient water flow of up to 6,000 GPH (and maybe a little more) without sacrificing filtration efficiency. As with all other Aquadyne filters the 16,000 comes standard with the Dynamax air assisted backwash system.

• Supports up to 330 pounds of fish.
• 4.4 Cubic feet of bead media (160 lbs)

Advanced filtration systems for Koi ponds now with NEW K+ Media

Building on the tried and tested technology that has been present in the world renowned Nexus, the team at Evolution Aqua have gone even further to enhance their number one koi pond filter. 

The Nexus 220+ and Nexus 320+ filters now come with a new filter media called K+ Media in the moving bed outer chamber for vastly improved biological filtration and faster filter maturation. The new Nexus+ filters are now supplied "auto ready", with factory fitted fixings already in place, making it even easier to upgrade to the Nexus Automatic Cleaning System.

How the Nexus Works

Water from the pond enters the nexus via the inlet into the inner chamber which works as a vortex, allowing larger solids to settle out. Water then passes through the grills in the stainless steel “Eazy” filter, where the finer particles are removed by the static bed K1 Micro® filter media. The clean water then passes to the outside chamber of the Nexus for biological treatment before returning to the pond. At this stage, biological breakdown occurs through different strains of bacteria and filter feeders living on the protected surface area of each K1+ Media filer. The bacteria convert Ammonia and Nitrite into less harmful Nitrate. Water then passes through the exit grill into the outlet and returns to the pond.

Continuing our long standing reputation for innovation, the Nexus Automatic System now enables Nexus owners to benefit from a fully automated cleaning cycle

Physically turning ball valves and manually switching pumps on and off will now be a thing of the past thanks to the Nexus Automatic System. All of the key processes that form the cleaning cycle are now controlled automatically with this easy to install kit.

Key Features
• Hassle free way to clean Nexus filtration systems
• Automates the cleaning process of the Nexus
• Easily fits onto Nexus filters (post 2006 models)
• Electronic control box automatically operates valves and pumps
• Adjustable timer controls the frequency of the automatic cleaning cycle to suit the user’s needs
• Easy to set up for multiple cleaning cycles
• Manual cleaning cycle can be carried out if needed, at the touch of a button
• GRAVITY and PUMP FED versions available

A compact member of the Nexus family, the EazyPod is a mechanical and biological filter system for garden ponds up to 5,333 gallons or Koi ponds up to 2,640 gallons. The EazyPod utilises static K1 Micro, which provides enhanced biological benefits, even when using the EazyPod solely as a mechanical waste filter.

• Mechanical and biological filtration.
• Very eazy to install and operate.
• Quick and eazy cleaning cycle.
• Works equally well pump or gravity fed.
• Ideal as a filter on a quarantine system.
• Also ideal for use as a pre-filter, polisher or on a skimmer line.

The EazyPod Automatic is a self-cleaning, mechanical and biological filter system for ponds up to 2,640 gallons.

The integrated control box contains an adjustable timer which initiates a cleaning cycle automatically - meaning your filter will clean itself even when you’re not there! Inside the control box, the electronic connector blocks control the automated waste valve, along with your choice of circulating pump (not supplied). It even houses an integral air pump which kicks in automatically to clean the K1 Micro media.

Crystal clear, healthy water is achieved by K1 Micro filter media, which also provides enhanced biological benefits by way of its protected surface area.

The Eazypod UV Automatic features an integrated 18 Watt UVC built in to the inlet section of the filter, helping to clear green water. Available in 2 models, users can select either the EazyPod Automatic or the EazyPod UV Automatic (with built-in 18 watt UV). 

The Aquadyne EcoSphere filtration systems are excellently suited to filter ponds and other aquatic habitats. Both models come standard with an Air Backwash system that performs just like the larger Aquadyne systems except in a small footprint package for smaller water features, ponds, aquaponic systems, quarantine systems, or other small aquatic habitats ranging in the 1000 to 4000 gallon class. These systems offer an efficient water flow. You can backwash with as little as 15 gallons of water. They include a 1.5" control head with 1.5" ports in/out, with (3) ea. 1.5" self-sealing unions included. These systems are also suitable for an indoor, large volume aquarium filter. These units are also an excellent starter for small laboratory research or aquaponic applications.

The Oase Clear Water Guarantee is your assurance of clear water down to three feet, a guarantee like no other. Precisely engineered and matched components function in concert to remove not only suspended solids for excellent clarity, but toxic wastes as well, assuring high water quality. Filter pumps designed to pass solids pick up and deliver fish wastes to multistage filters. Filter foams of varying densities strip out solids and particulates. Beneficial bacterial colonies remove ammonia, nitrite and nitrate, eliminating nutrients in the water. Finally, water is bathed in ultraviolet light in an EPA-certified clarifier to further inhibit the growth of algae. You will be able to read the 1" mark on a measuring tape three feet below the surface, guaranteed.
