The Vortex Diatom Filter D-1 is a
high-speed mechanical filter that is designed to fine filter aquarium water
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 to 55 gallons with an “active” flow rate
of 150-200gph. 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 D-1 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.
A minimum charge for the D-1 Diatom Filter is about one cup. To start the filter
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-1 Filer you will
have to crimp off the exhaust hose and allow the filter to run for about two
minutes to recoat the filter bag before releasing the flow.
When the flow from the exhaust tube is weak or the Diatom Filter is visibly
dirty, it is time to clean and recharge the unit with a new charge of Diatom
To clean and recharge the filter a back flushing method may be used by
disconnecting the filter from the aquarium and connecting it to a water faucet.
The incoming water forces the dirty water out to make sure all the waste
material is flushed clean. The filter can then be recharged.
