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 (air blower) and works most exceptionally with any standard two speed motor or many popular high efficiency 1/4Hp pumps. 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.

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 recalculating 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 anywhere near 50PSI on the tank. This simply would not occur in any practical application so we consider it just a perk.

On The Other Hand, you should be aware that due to the spin welding that some competitors must use to attach fittings to their tanks, and thin tank wall construction, they can only rate their tank pressures at 15PSI Max. Hardly sufficient for medium head pumps capable of any decent flow rate.
