This is the next generation of filters and the best tool for
Koi ponds. The Ultima II is specifically engineered to meet the
environmental demands of ponds.
Cleaning the filter is done by internal jets.
The Ultima II is also the ideal
Pond Filter where very high flow rates are desired.
There
is a patent pending on this tubular media which has low head loss
and a very high biofilm surface.
The “Y” shape on the inside
and wings on the outside affords a protective surface under
backwashing and our patent pending backwash system will keep the
media from clogging. The same properties have been added to this
media in three different sizes with random lengths and diameters
to avoid stacking. One cubic foot of Ultima II media is equal to
750 square feet of surface area.
