Aquadyne .60B Professional Pond Filters – Up to 2000 Gallons – AD2000

Description

Aquadyne 2000 – Model .60B Filtration system is excellently suited to filter ponds and other aquatic habitats up to 2000 gallons. The Model AD2000 comes standard with the Dynamax Air Backwash system that performs just like the larger Aquadyne systems except in a small footprint package for smaller water features and ponds.

This filter is an excellent performer with most any pump. You can use a small submersable pump from 1000 Gph all the way up to an external 3900 Gph pump. If you intend to use a submersable pump, please use the order number AD2000(S) for a submersable riser column.

The Dynamax Air Assist Backwash aggressively agitates the debris collected in the media bed and suspends it in the water column which is easily backwashed to waste, conserving water, and deep cleaning the filter media bed. The AD200 is very suitable for an excellent indoor large volume aquarium filter. This unit is also an excellent starter for small laboratory research applications.

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.
