CLEAR POND FILTER
Instructions
Filtration
Whether you are a beginner or experienced water gardener, you will probably have one objective and
that is to achieve a clean, clear healthy pond. Ponds can be affected by various factors such as
unconsumed fish food, decomposing vegetation and fish excrement. If these pollutants are allowed to
accumulate, in time they will become harmful to your fish. The use of a biological filter will remove
these toxins (nitrite, ammonia) and provide good quality water with the additional benefit of reducing
algae growth.
This unit is manufactured
in the EEC and conforms to CE

Your filter may take 3 - 6 weeks to fully mature with beneficial
bacteria, however you can prematurely speed this process
up by using Oasis Filter Active (Ask your retailer)
Stage 1 Ultra Violet Clarifier (U.V.C) This is situated within the lid of the filter. As water is pumped
through the unit, the algae cells are penetrated by the U.V.C light destroying their ability to multiply and
causing them to flocculate (bond together). This process creates larger particles which can then be
removed more effectively by the Biological filter. The U.V.C will clear the water within 2 - 4 weeks and
additionally the mild sterilizing effect will help to reduce harmful bacteria levels.
Stage 2 Mechanical Heavy sediments (Leafs, Blanket Weed & Fish Waste) are filtered from the
st
water, as the water passes through the brushes. (1 Chamber)
Stage 3 Mechanical/Biological In the second chamber the water passes through the Bio Cartridge.
This media filters the smaller debris which is not collected by the brushes. The cartridge also allows
beneficial bacteria to grow on its surface.
Stage 4 Mechanical/Biological In the middle chamber, there are 3 layers of reticulated foam.
Suspended particles are filtered out as the water passes through.
Green Foam: Course Grade
White Foam: Medium Grade
Blue Foam: Fine Grade
Biological - Below the layers of foam, there is Biological Media called Flocor™. The purpose of this
media is to allow beneficial bacteria to grow on it's surface. Once matured the bacteria will breakdown
the harmful pond pollutants (Ammonia & Nitrite) converting them into Nitrate... Which is naturally
absorbed by pond plants.
Filter Installation
1). Ensure that all fittings are watertight. Use only the correct size outlet
pipe for the filter outlet/s. (Please ask your stockist for details)
2). Site the filter on a firm level base so that the outlet is higher than the
water surface of the pond, or above the height of the waterfall, if you
choose to have one. Keep as close to the pond as possible.
3). From the pump in the pond, attach a suitable size and length of hose to
the inlet of the filter and secure using a hose clip.
4). Your biological filter must be run 24hours a day to maintain the bacteria colony.
5). Please allow between 3 to 6 weeks for the biological media to mature.
This unit is not submersible and must be positioned where it can not Be
accidentally knocked into the pond or waterfall.

Filter Maintenance
water entering the overflow, it is an indication that the media will require
cleaning.
2).
Remove the foams individually and clean in a container of pond water. The foams
contain some beneficial bacteria and it is important that they are not cleaned in tap
water.
5). Re-fit the foams before they dry and in the same order that they were removed
dimpled side uppermost. E.g.
Top Layer: Green Foam: Course Grade
Middle Layer: White Foam: Medium Grade
Bottom Layer: Blue Foam: Fine Grade
6). The Flocor™ media should not need cleaning, however, if you need to remove
accumulated silt within the tank, then the media can be removed and placed into a
container of pond water while the tank is cleaned. (This will preserve the beneficial
bacteria)
7). Stage 1 Is a quick de-sludge, simply open the drain valve until the water runs clear.
Stage 2 Simply connect your garden hose to the hose connector, open the drain valve and
turn on the water. You do not need to remove the media as the water passes underneath it.
Therefore preserving the beneficial bacteria.
1). Your filter is fitted with an overflow system (see diagram). If you see
The Brushes in the first chamber should be kept reasonably clear from any
heavy debris. These should be removed and washed in a container of pond
water.
3). If the Bio cartridge in the filter seems clogged, then remove the media and rinse in
a container of pond water. DO NOT CLEAN THOROUGHLY JUST ENOUGH
TO CLEAN OFF ANY LARGE SOLIDS. Never allow media to become dry.

U.V Maintenance
1). After a period of time the quartz sleeve may become fowled with deposits
of algae and limescale. These should be removed using a suitable
cleaning agent, taking care not to scratch the surface of the quartz.
2). The UV lamp must be removed every 12 months or after 8000 hours of
use. Although the lamp may still be showing a blue light, it is no longer
producing sufficient UV to destroy algae and bacteria.
3). For UV maintenance, Oasis UV Maintenance Kit comes complete with
