Aquadyne 4.4C Professional Pond Filters – Up to 16000 Gallons – AD16000

Description

The Model AD16,000 – Model 4.4C filtration system includes a 2″ High effeciency Control Head with 2″ ports in and out, with 3ea. 2″ self-sealing unions included. The Model AD16,000 enters the commercial grade market of bead filtration for ponds or other aquatic habitats in the 16,000 gallon class. The Model 16,000 is used in water features ranging form very large backyard lawnscapes to fisheries, to public aquariums, and the most descriminating laboratory applications. Here also the AD16,000 far exceeds the performance of most all competitive filtration units in it’s class, 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 effecient water flow of up to 6000 Gph (and maybe a little more) without sacrificing filtration efficiency. Be sure to read the “Fuzzy Tech” documentation for a generous amount of additional technical information regarding water flow. As with all other Aquadyne filters the 16,000 comes standard with the Dynamax air assisted backwash system.

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.
