AZFlo Pond Pumps: Significant technological and design innovations improve pump performance with greater energy efficiency. The reliable Max-Flo Waterfall and Filter Pond Pumps operate on less wattage than the prior models without compromising flow rate. Max-Flo are fitted with Smart Pump Technology. This internal, self-regulating system tracks power consumption, hydraulics and impeller direction. In other words, these smart pumps use only the required amount of power for operation!

Aquadyne Filters: AquaDyne Filters are recognized worldwide as one of the finest Koi pond filtration systems ever made! Selecting a filtration system will probably be one of the most frustrating decisions you will have to make in building your water garden paradise. It would be so easy to say just go out and buy yourself a good filter and install it, but that would be like saying just any car will get gas mileage, without bothering to tell you how much.

Without going into great detail, it is very important to have a biologically correct filter system attached to your pond if you plan to have a fish population. You will first need to ask yourself how much labor are you willing to put into keeping your filter clean. There is a direct relationship between filter cost, and labor required to maintain, that is, within a range of quality filters. It also seems that there is an endless line of filters waiting to go inside your pond for almost anything you want to pay for them. One thing to consider is whether you are looking for a simple mechanical filter to keep the suspended solids out of a small pond with very few fish, or are you seeking to biologically consume the waste products that your fish population will be producing, no matter what size the pond or regardless of how many fish you have. As you will see in the pages that follow you will discover one of the newest and most functional and highest success rated filters available on the market today.

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.
