The Vortex Diatom Filter Model XL is a

without disturbing the natural bacteria levels. The filter is invaluable in
keeping a parasite-free, clean, well balanced and healthy aquarium. It can be
used for fresh and saltwater tanks up over 55 gallons with an “active” flow rate
of 200-350gph. It has 432 square inch filter area. The Diatom Filter is equipped
with a 3000 RPM motor shaft that is connected directly to the impeller. It is
designed for continuous operation (maximum of 8 hours per week).
The Diatom XL filter features and adjustable and directional flow and has an
electrical on-off switch. It has a thermally protected motor which provides
quiet operation. The filter is self-contained and back- flushes clean without
taking the filter apart.

or if it has been turned off for any length of time, the Diatom Filter Powder
will have fallen off the filter bag and settled into the bottom of the plastic
jar. The powder is the filter, not the bag. To restart you D-XL Filer you will
