The Model 2.2 is an excellent choice for a bead filtration system within a given price range for larger ponds. The Model 2.2-B by far exceeds the performance of the standard 2.2 at a slightly higher initial cost at the benefit of turbo-charging the effeciency of your filter. Carefully compare both filters performance data. Here again, we now fit the Standard 2.2 also with the necessary bulkheads for a later simple backyard conversion to the Model 2.2-B. The standard 2.2 can also be converted to a 2.2-B yourself with no special tools. If you are relatively sure that you will likely convert your filter to a Dynamax system at a later date, we advise that you not wait and purchase the appropriate model initially. By the time you decide to convert, you could have had it running from day one with no concern of conversion.
