Bioforce 3000/5500/8000
UVC - POND FILTER
PLEASE READ CAREFULLY
AND KEEP THESE
INSTRUCTIONS
Hozelock Cyprio Bioforce filters are a
new concept in fish life-support
systems for garden ponds. They are:
SMALL yet EFFICIENT
EASY to CONCEAL
 TROUBLE-FREE to MAINTAIN
And they can be sited almost
anywhere (See Fig 1).
When used with the appropriate
pond pump, the Bioforce will remove
unwanted solids from the water and
convert dissolved organic and
chemical fish waste into harmless
compounds. In addition, the
combined filter/UVC units will give
Guaranteed Clear Water if the advice
given in the Filter Equipment
Selection Chart and in these
instructions is adhered to.
SAFETY AND ELECTRICAL
CONNECTIONS
! WARNING: ALWAYS UNPLUG OR
DISCONNECT ALL APPLIANCES IN THE
POND FROM THE ELECTRICITY SUPPLY
BEFORE PUTTING YOUR HANDS IN THE
WATER WHILST EQUIPMENT IS BEING
INSTALLED, REPAIRED, MAINTAINED
OR HANDLED.
! This product is NOT SUBMERSIBLE,
and should be sited where it
cannot fall into the water or
become waterlogged. However,
the design is weatherproof, and
Bioforce filters can safely be
installed outdoors.
! Direct exposure to ultra-violet
light can damage eyes and skin.
DO NOT attempt to view the lamp
when lit, except briefly through
the viewing lens.
! This product is supplied complete
with 5m of 3 core electric cable.
For connection to the mains
supply, use only three-core cable
Ref: HO5 RN-F. This has a
minimum copper cross-section of
0.75mm2with Polychloroprene
Rubber Insulation. The
termination to the mains supply
should be permanent, inside a dry
weatherproof enclosure, through
a double pole switched fused spur
with a minimum contact gap of
3mm - (disconnector) to BS 3676 -
and fitted with a 3 or 5 amp fuse.
! Exposed cable runs should be
sensibly positioned, and protected
if necessary by armoured conduit,
especially if contact is likely with
gardening equipment such as
forks and lawnmowers, or
children or domestic animals.
! A 10mA or 30mA Residual Current
Circuit Breaker (RCD) MUST be
fitted to the mains supply.
! The supply cable cannot be
replaced. If the cable is damaged,
the unit should be discarded.
! The installation must conform to
the national and local wiring
regulations which could include
the use of plastic or metal conduit
to protect the cable.
! If in any doubt about wiring to
the mains supply, consult a
qualified electrician or your local
electricity authority.
! Protect from frost if the unit is not
to run year-round. In cold winter
weather (when fish are not active
and algal growth ceases), the unit
may be switched off. It should
then be drained of water,
removed (if possible) from its
installation and stored in a dry,
frost-protected area.
CHOOSING THE RIGHT SIZE
The Filter Equipment Selection Chart
overleaf gives general guidelines on
the specifications of pump, filter, and
flexible hose diameter for garden
ponds up to 8000 ltrs (1700 gallons).
For best results, the following
condition factors must also be taken
into account.
DEPTH
Hozelock Cyprio recommend a
minimum depth of 1.2m (4’) for Koi
ponds.
For a pond with an average depth of
less than 0.75m (2’ 6”) the Condition
Factor is + 25%. Shallow ponds are
subject to full penetration of
sunlight, and warm up quickly. This
encourages algae growth.
LOCATION
Pond location determines the daily
amount of sunlight or shade a pond
receives. Ponds exposed to full
sunshine throughout the day have a
Condition Factor of +25%.
CLIMATE
Climate affects water temperatures
and fish activity rate/feeding
requirements. The more active the
fish, the greater the demands on the
filtration system.
In hot climates (eg South Africa), the
Condition Factor is +35%
In temperate climates (eg Southern
Europe), the Condition Factor is
+15%
In a Northern European climate (eg
most areas of Great Britain), the
Condition Factor is +0%.
EXAMPLE
You have a 2300 ltr (500 gallon)
goldfish pond 60cms (2’) deep
(Condition Factor +25%). You live in
London - a Northern European
climate (Condition Factor +0%). The
pond is exposed to full sunlight
(+25%). The effective volume of your
pond is therefore increased by 50%
(25% + 25%), and you would need to
size your equipment as though your
pond held 3400 ltrs (750 gallons).
1. INSTALLATION
1.1Important: The pump supplying
this unit must not have a
maximum head exceeding 6m (8.5
PSI, 0.6 Bar)
1.2Bioforce is a pump-fed, pressurised
external filter with integral UVC,
ideally suited to in-ground
installation adjacent to your pond
or concealed at the top of a
waterfall. They may also be
positioned above ground if
desired.
If you choose to part-bury your
Bioforce UVC filter , the
excavation should be firmly back-
filled with compacted sand to
support the unit.
1.3 Bioforce filters incorporate inlet
and outlet hosetails to fit
20/25mm (3/4” - 1”) Cypriflex hose
(refer to Equipment Selection
Chart overleaf). The pump and
filter outlet pipe should be as far
apart as possible for optimal
water circulation, so bear this in
mind when purchasing, measuring
and cutting the Cypriflex hose.
1.4 Cut the hosetails on your Bioforce
to suit the diameter of the hose
used (see Fig 2). Connect the hose
from your pump to the inlet
hosetail and secure with Hozelock
Cyprio hoseclips, available
separately. Do not overtighten.
The outlet hose is secured in the
same way. Avoid kinks and bends,
ATTENTION - UV CAUTION
Exposure to Ultra Violet (UV)
radiation can be dangerous and
cause damage to eyes and skin.
Under no circumstances should
any attempt be made to gain
access to the lamp when the unit
is switched on.
From 1st January 2005 installing this
product in the garden is classed as
'notifiable' in the revised Building
Regulations for England and Wales.
The Regulations now require you to
tell your local authority building
control department that you intend
to install this product before
installation. Your local authority will
let you know how you can get your
installation approved.

and keep this hose run as short as
possible in order to minimise flow
restrictions.
2. LAMP INSTALLATION
AND REPLACEMENT
2.1 Lid removal
Undo the seven securing clips
and gently remove the lid (If
there is any difficulty, insert a
coin into the slot provided and
turn gently).
2.2 Remove the screw securing the
central tube to the lid and rotate
the tube anti-clockwise and pull
to release (See Fig 3).
2.3 Remove the quartz glass tube in a
similar way (See Fig 4).
2.4 With the lamp holder now
accessible, push the lamp into
position (See Fig 5).
2.5 Re-assemble the quartz tube into
position, ensuring the screw boss
is re-aligned and screw re-fitted.
Re-assemble the central tube to
the lid, twisting into position, and
refit the securing screw.
2.6 Lid fitting
Refit the lid, making sure the
seal is in position and free of dirt
and debris. Add a light coating
of silicone grease to the seal if
required to aid assembly. Re-
engage the seven securing clips,
ensuring all are firmly in place,
and retighten the viewing lens.
3. WIRING
3.1 IMPORTANT: This product is
designed to be connected to a
mains supply housed in a dry,
weatherproof enclosure.
3.2 WARNING: This appliance MUST
be earthed, and it is essential that
the connections are made using
the following code:
BROWN - live
BLUE - neutral
GREEN/YELLOW - earth
4. FLOW RATE
4.1 The entire pond volume should
pass through the Bioforce every 1
1/2 - 3 hours, the fastest flow rate
being recommended for Koi
ponds. Do not exceed the
maximum flow rate, as stated in
the Equipment Selection Chart
overleaf. The correct flow rate is
essential if you are to obtain clear
water. If the flow is excessive for
your installation it may be
necessary to adjust the flow to
achieve the 1 1/2 - 3 hour turnover
rate using a Hozelock Cyprio Flow
Control Hose Tap.
4.2 Small-diameter hose,
unnecessarily long hose runs and a
high pumping lift (‘head’) can all
considerably reduce a pump’s
output. We recommend choosing
a pump that will deliver the
required flow against full static lift
(= vertical distance between pond
surface and filter inlet), plus 0.6m
(2ft) to allow for friction losses in
hoses.
4.3 The objective of filtration is to
transfer waste material from the
pond into the filter, and so any
pump used as part of the package
should be capable of handling
solids. We recommend the
Hozelock Cyprio Titan filter pump,
specifically designed for ponds in
the size range covered by
Bioforce. The pump should be
positioned on the bottom in the
deepest part of the pond, as this is
where solids accumulate.
4.4 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 gallons or litres per
hour
5. PERIODS OF OPERATION
5.1 Maintain filtration 24 hours a day
throughout the fish feeding
season (until water temperature
falls below 10ºC), but preferably
all year round. In the winter,
operating the pump and filter will
maintain a background level of
friendly bacteria in the Bioforce,
and will help prevent the pond
icing over in all but the severest
weather conditions. If the pump is
switched off for winter, the filter
media (foam and/or Kaldnes™
biomedia) must be thoroughly
washed before resuming filtration
in the spring, and your Bioforce
will need to be re-matured from
scratch (see ‘Maturation’, 7.1).
Never feed your fish when the
filter is not in use.
6. FISH STOCKING DENSITY
6.1 Under normal conditions and
feeding regime, the Bioforce
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.
7. MATURATION
7.1 Biological maturation means that
the filter has built up sufficient
nitrifying bacteria to convert
harmful fish and other organic
waste (ie Ammonia, Nitrite) into
harmless Nitrate. The process
normally takes 6-8 weeks, but is
dependent upon many factors
such as water temperature,
feeding rate and stocking density.
(It is recommended that you do
not switch your UVC on during
this period).
8. CLEANING YOUR
BIOFORCE
8.1 Bioforce filters deliver maximum
performance with minimum
maintenance. If the pond is very
dirty, the filter may need
cleaning every few day’s at first,
as it takes up waste matter very
quickly. Once the pond becomes
clearer, there will become less
waste to remove, so the filter
will need cleaning less often.
Pressurised filters are at their
most efficient when the foam
becomes partly blocked.
However, as blockage increases,
less water can flow through the
foam and cleaning becomes
necessary.
Note; Prolonged use of the filter
under ‘full’ conditions will result
in difficulty in cleaning and may
reduce the life of the foam discs.
8.2 IMPORTANT: The possibility of
dirty water being back siphoned
through the filter and into the
pond can be overcome by lifting
the submerged outlet pipe from
the water and above the height
of the filter lid before switching
off the pump. This will break any
potential siphon. In conjunction
with this, before any attempt is
made to remove the lid, the
viewing lens needs to be slightly
unscrewed to relieve any
additional potential siphon lock
in the system.
8.3 Thorough cleaning
Undo the seven securing clips
and gently remove the lid (If
there is any difficulty, insert a
coin into the slot provided and
turn gently). Gently remove the
foam from the filter vessel and
squeeze out the dirt. Using the
water in the filter, rinse out each
foam in turn using a sponge
action and squeeze the dirty
water outside the filter vessel.
Reposition the clean foam(s)-
ensuring they lie flat. It may help
to remove some of the water
from the vessel.
Refit the lid, making sure the
seal is in position and free of dirt

and debris. Add a light coating
of silicone grease to the seal if
required to aid assembly. Re-
engage the seven securing clips,
ensuring all are firmly in place,
and retighten the viewing lens.
8.4 Back-Flush cleaning
It is possible to increase the
interval between thorough
cleans by back flushing the
Bioforce filter. This is simply
achieved by swapping over the
inlet and outlet pipes or
connecting a separate waste pipe
to the Bioforce inlet and
switching the pump back on.
Note: Ensure that the return pipe
is not left in the pond but is
allowed to go to waste. Swap
the pipes back over once water
from the filter runs clear (about
30 seconds).
8.5 Normally, there is no need to
remove the foam support plate.
However, if you need to access
the biomedia, remove the
support plate by lifting it clear of
the vessel (See fig.6). Make sure
you refit the support plate
correctly, so that the bio media is
not released.
9. CARE OF THE UV QUARTZ
TUBE
9.1 Especially in hard water areas
the quartz sleeve sheathing the
UVC lamp may become covered
in lime scale. This will reduce the
efficiency of the unit if it is
allowed to build up. To clean,
switch off the pump and the
power supply to the UV, remove
the lid and central tube, as
described in note 2.1, and wipe
the quartz tube with a soft cloth
moistened with a gentle
cleaning agent such as vinegar
(See fig 7). The maximum life of
a lamp is 12 months continuous
use. Replace the lamp after this
time, even though it may still
glow.
10. WINTER STORAGE
10.1 IMPORTANT: When not in use,
the unit should be removed,
thoroughly washed and
cleaned, dried and stored in a
dry frost protected area.
Always store the unit with the
lid off to ensure adequate
ventilation and drying.
