Atlantic's Filterfalls are up-flow
filters. Water flows from the pump through
the bulkhead fitting into the swirl chamber at the bottom of the filter enclosure;
then through the
grate and filter mat where solids are removed;
lastly, through the media bag and filter material, and out
over the spillway.
Various plastic materials and mats, or natural materials such as lava
rocks,
sand, gravel and plants (not supplied) may be utilized as filter media.
