 Aquadyne ~ Dyna-max
Forced Air Bead Cleansing Systems
Standard Equipment on Models 1.1B,

* Boosts Total Biological Filtration Capacity Approximately 30% . . . . . . . The Dyna~max forced air cleansing allows thorough washing of bead media through a significant increase in turbulence of media prior to backwashing. The forced air washing, completely breaks up the entire media bed and frees all fine materials that may otherwise remain suspended in the media for further biodegrading.

* Reduces the Water Necessary to Backwash by as much as 80% . . . . . . During a normal non air-assisted backwash cycle, the Model 4.4 would typically require between 200 and 300 gallons of water to effectively clean the filter of waste. With the Dyna~max system you can backwash the same filter with as little as 60 gallons of water. This is most desirable for those wishing to install a larger filter on a pond of a lesser volume than the filter is rated for, because very little make-up water has to be added to the pond after a backwash cycle and a much larger fish load can be maintained in a smaller environment, while greatly extending the time between backwashing.

Dynamax is installed on all B and C models of this page.

Model 2.2-B Excellently suited for ponds up to 7500 gallons.

  Support Up to 150# of Fish 2.2 cubic feet of media Diameter 24" Height 46" Maximum Pressure: 50 PSI Average Footprint with pump and UV: 24"D x 40"W

The Model 8.8-C is definitely the Mac Daddy of all bead filters in its price range. Boasting worry free maintenance on ponds up to 28,000 gallons. Our latest proving ground for high fish load concentrations on the Model 8.8 is a commercial fishery that is running 600 pounds of fish in a single living, growing system with generous feeding habits, yet they claim a most excellent water quality with regard to waste management. At such a heavy load, their practice is to take a few minutes and backwash the system every day to eliminate the mechanical waste from the heavy feeding that goes on in the commercial facility. In the average large pond installation, the sheer volume of the Model 8.8 can bless you with only having to backwash as little as once every 3 weeks. These farmers joke that you really can clean the filter with a cup of coffee in your hand.

As of June 1999 we have introduced a new option for Aquadyne which has become standard on many models. This is the Dyna~Max Air Assist Bead Pre-Rinse and works most exceptionally with any standard two speed motor or many popular high efficiency 1/4Hp single speed or similar pumps, and yes, even submersible pumps have been used on these filters with great success.

We have also introduced a whale of a filter in the Model 8.8 for the year 2000. This is a phenomenal filter in a low profile package with the most exceptional performance on the market due to the custom machined inverted diffuser system for maximum water dispersion within the biological filter bed.

Clarifying Flow Rates:

Stated average filtration flow rates are average. You can increase or decrease the flow rates as you like. However the maximum filter flow rating is intended to reflect maximum solids removal while maintaining reasonable biological contact with the bacteria living on the filter media to effectively remove ammonia and nitrite from the water system within the parameters of the specified fish loads. Minimum backwash flow rates indicated, reflects the flow rate that most effectively separate solid waste products from the bead media and flush the waste products from the filter with a minimum of water loss. The minimum backwash flow rate for your particular filter many well be lower, depending on A: Whether of not your system has a Dynamax option installed, B. The amount of fish waste or plant waste in your system produced by various feeding habits. C. The overall frequency in which you backwash your particular system. All living aquatic environments have many variations on the particular biological chemistry with regards to active waste products in the pond. Some may have only fish waste, while others may have fish waste, plant waste, and even simentation waste from soil products washing into the pond. Aquadyne is specifically designed to operate in all types of pond environments handling most waste with little difficulty.

 Chart, Data Clarification:

The Maximum Pond Size shown indicates the maximum pond size for greatest biological efficiency of a given system. Pond size can also be significantly smaller than the maximum rating. By using a larger system on a smaller pond, you will only further increase the biological cleanliness of the pond environment. Likewise, the pond could also be slightly larger than the rating on a system provided that there was not a significant fish load. (See Fish Capacity Data)

The Minimum Flow Rates indicated in the chart indicate the minimum flow rates required to backwash or advanced backwash the system. Flow rates during the normal filter cycle can be significantly slower than indicated in the chart. However, during the backwash cycle, you must have the ability to increase the flow to the minimum rating for a proper backwash. Often the use of a two speed pump will allow you to run a very slow flow rate with a lower power consumption while filtering, and only use the less economical high speed for backwashing. The maximum flow rates listed are a cross section of two factors. Mechanical control head port size for efficient flow without significant restriction, and contaminated water contact exposure to the billions of beneficial bacteria residing within the filter. Without a doubt, slower flow during the filter cycle is better, but, a faster flow rate also places the recirculation water in contact with the media more frequently, netting near identical nitrification results.

The Maximum Pressure Rating all Aquadyne systems is a whopping 50 PSI ! --- We actually consider this a non issue, because the Central Diffuser Column on our filter is so efficient and non-restrictive that you would have to install a 5HP pump and have the filter half clogged to put 50PSI on the tank. This simply would not occur in any practical application so we consider it just a perk. However, you should install a water pump that most nearly matches the performance rating of the filter that you are choosing. As a caution, there have been instances where a pump was arbitrarily chosen because of head pressure without the consideration of water volume. This can potentially cause a tank gasket to blow out. For example, if you were choosing a Model 2.2 or 2.2B, the recommended water flow rate for maximum filtration efficiency is between 1000 and 4000 gallons per hour. That is not to say that the filter would not perform well at 5000 gph. BUT, what some contractors tend to do is use high head swimming pool pumps on fish ponds because they are cheaper to install. The basic deal is that the average 1Hp swimming pool pump can pump about 5000 to 7000 gallons per hour, which is not the real problem. The real problem is that when a filter begins to load up with fish waste and debris this swimming pool pump with its high head impeller tries to maintain this high rate of water flow which in turn can put excessive pressures on a filter tank which can cause gaskets to leak. High head swimming pool pumps also cause other problems as well, but we will discuss this later. As always, we are available to answer any confusions that you may have when making an equipment choice.

On The Other Hand, you should be aware that some filter manufacturers use a technique called spin welding to attach fittings to their tanks, and thin tank wall construction, these tanks can only be rated at pressures of around 15 PSI Max. This is not sufficient for medium head pumps capable of any decent flow rate. We do not use these substandard manufacturing practices.
