Aquadyne 2.2B Professional Pond Filters – Up to 8000 Gallons – AD8000

Description

The Model 8000 – Model 2.2B filtration system is an excellent choice for a bead filtration system for larger ponds. The Model AD8000 far exceeds the performance of most all competitive filtration units in it’s class. Entering the 8000 class, the AD8000 truly performs spectacularly for ponds this size range.

The 8000 is easily the most popular Aquadyne filter produced. This filter 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 8000 with as little as 50 gallons of water. In an 8000 gallon pond you will hardly even notice a water loss.

The AD8000 is also outstanding as an upsized filter for smaller ponds. This is especially useful when filters need to be left unattended for longer periods of time between backwashing. The 8000 can use a very wide range of pumps, single speed, dual speed, variable speed, submersible, low head, high flow or high head. See the “Fuzzy Tech” advisory for specifics about upsizing and pump capacity in the FAQ’s.

The Model 8000 is very well suited for applications where ponds or research applications under 8000 gallons need to be heavily stocked. The large media bed allows for an extraordinary accumulation of beneficial bacteria to consume high amounts of ammonia and nitrite. Also works exceptionally well for medium to moderately sized aquatic environments for alternative species exhibits.

Backwashing:
Initially you will let your filter run for a period of several days up to two or three weeks depending on mechanical loading of removed solids. We recommend that you not backwash your new filter until it begins to load up with solids to the point of slowing your water flow down. This will allow naturally occurring bacteria including Nitrosomonas and Nitrobacter to cycle and form a living colony inside your filter media. If your water flow slows due to solids being removed from the water then by all means backwash it. Otherwise, resist the temptation to backwash the filter and let it be. You may leave your pump running when performing backwashing operations with few exceptions. We suggests turning the pump off, but you are free
to choose. See installers instruction manual for more details.

Backwashing With Dynamax Air Assist: Turn the main pump off, and place the main control valve in the
RINSE position. Plug in the Dynamax air blower and open the blower control valve. The system will belch a wave of dirty water and compressed air. Allow blower to run approximately 2 to 3 minutes, then close valve and switch off blower. Reposition the main control valve to BACKWASH then turn the pump back on (high speed if you have a 2 speed motor). When the sight glass begins to run clear, return the control valve back to filter and reset your pump to low speed (if you are using a 2 speed pump) and you are finished. This process takes 5 minutes max.

Backwashing Without Dynamax Air Assist: With the pump off or on, reposition the top control handle to the BACKWASH position. At first you will see only clear water flow out of the waste line, then the dirt and waste will begin to exit the filter. Once the water runs clear, reposition the handle to the RINSE position to reload the media into the top of the tank and allow the water to run again until clear. Finally, reset the control handle to the FILTER position and you are finished. Note: Rotating the control handle back and forth several times between Backwash and Rinse positions and finally back to Backwash greatly improves debris removal on non-Dynamax systems.

After each backwash, open the sludge valve at the bottom of the filter for 3 to 5 seconds after your control head has been returned to the filter position. This will discharge any sediment that has settled in the bottom of the filter tank during the filtration or backwash cycle. You will probably notice that the discharge from the waste lines will have a very foul odor. This is good, and a sign that your beneficial bacteria are developed and healthy. And most important!, plan on spending most of your time ignoring your filter system, because you will be free from worrying about cleaning your filter and free to enjoy your pond and its friendly inhabitants.
