How to check your flow rate: Take a container of a
known volume and time how long it takes to fill (in
seconds). Then divide 3600 by the number of seconds
it takes to fill the container, and multiply by the volume
(litres or gallons) of the container. The result will be the
flow rate in litres or gallons per hour (lph or gph).
2.3 Fish Stocking Density: Under normal conditions and
feeding regime, the Bioforce revolution range will
support up to 50cm per 1000 litres (10” of fish per
100 gallons) of pond capacity. Introduce fish slowly
over the first few weeks, up to 20% of maximum
recommended level, increasing this if you wish to 50%
after six months. The balance will allow for fish growth.
2.4 Pond Treatments: Some medications/ treatments
can degrade very quickly by UVC radiation. Consider
switching off the filter during disease treatment. The
mechanical and biological filtration will continue to
work.
If treating your pond for blanketweed, turn off your
pump and filter for the duration of treatment until the
treated blanketweed has been removed from the pond
2.5 Extra care should be taken with any hose connections
as leaks will result in loss of water from the pond.
Installation
3.1
Important: Do not use a pump with a flow rate greater
than 8000lph or a maximum head greater than than
5m with the Bioforce revolution range of filters.
3.2 Important: Bioforce revolution filters must only be
installed in an upright vertical position (Fig. 6).

3.3 Bioforce revolution filters are pump-fed, pressurised
external filter and UVC units, suited to either above
ground (Fig. 7) or in-ground (Fig. 8) installation
adjacent to your pond or concealed at the top of a
waterfall.

If you choose to install your filter above ground, place
the filter on flat level ground.
If you choose to part-bury your filter, the excavation
should be firmly back-filled with compacted sand to
support the unit. If you choose this type of installation,
you should leave a minimum of a 50mm gap between
the clamp and ground level ensuring it is easily
removable for annual maintenance.
3.4 Using small bore hoses leads to excessive restriction
of the water flow. The larger the diameter of hose
that you use the better the performance of the filter
will be, especially over long hose runs. The hosetails
supplied with this unit will accommodate 25mm (1”),
32mm (1¼”) and 40mm (1¾”) Cypriflex hose. We would
always recommend that on the Bioforce revolution
filters, that the 40mm diameter hose should be used to
avoid water flow restriction.

once you have selected
the hose diameter you
wish to use, cut the
steps off the hosetail
which are smaller than
the hose diameter to
eliminate restriction
(Fig. 9).
The pump which
supplies the filter and
the outlet of the pond
return hose should be
as far apart as possible
for optimal water circulation, so bear this in mind when
purchasing, measuring and cutting the Cypriflex hose.
Attach a suitable length hose between the supply
pump and the filter inlet (Fig. 10 (i)) securing the
hose to the hosetails using Hozelock Cyprio hoseclips,
available separately. Then connect a suitable length
of hose to the filter outlet (Fig. 10 (ii)) in the same way.
For details on the waste outlet (Fig. 10 (iii)), refer to the
section “Cleaning”.

Place the pump in the pond in a suitable location and
position the end of the outlet hose so that filtered
water returns to the pond.
Avoid kinks and sharp bends when positioning the
hoses. Keep the hose runs as short as possible to
minimise the restriction of flow.
3.5 Ensure the winding handle is positioned over the
electrical housing. Take the winding handle knob &
cover supplied and connect it to the cleaning handle by
locating it on the handle and clicking it in in place
(Fig. 11).
