We've used this filter for 15 years and recently found
a new way of using it. - as a prefilter. Matala media has allowed
this new way of utilizing this filter:
A set of 10 discs utilizing "step-wise" all four
grades of Matala media (3 black, 2 green, 2 blue, 3 white) surround
a finned standpipe. This creates mechanical and biological filtration
as well as solids separation, since this is an upflow filter.
Customizing the grades of Matala discs for your specific needs
is optional. For example when using this pressurized filter as
a prefilter to an Ultima II biological filter
