The Bioforce 12000 is a new concept in water
filtration for garden ponds.
It is :
• Small yet Efficient
• Easy to Install
• Trouble Free to Maintain
• Can be sited almost anywhere. (see fig 1).
Used with the appropriate pond pump,
they will improve water clarity, remove
unwanted solid matter from the pond
and convert dissolved organic and
chemical fish waste into harmless
compounds.
Pond size
The Bioforce 12000 can deal with
ponds of up to 12000 litres (2600
gallons) with fish, using a pump thats
providing a flow of 6000 litres (1320
gallons) an hour. However, for best
results, certain conditions may need to
be taken into account.
Ponds that are heavily stocked with
fish, less than 1.2 metres (4 feet) deep,
are situated in warm climates or
overexposed to direct sunlight will lead
to excessive algae growth and fish
activity. This results in greater demands
on the filtration system.
The pond sizing chart at the end of
these instructions give guidlines on
recommended pond sizes, relating to
these conditions.
1. WARNING!
Safety and electrical connections
1.1 Your Bioforce 12000 is weather proof
but not submersible
. Position the unit
conveniently near the pond, but not
where it can fall into the water or
become waterlogged.
1.2 Caution -Direct exposure to UltraViolet light can damage eyes and skin.
DO NOT attempt to view the lamp
when lit except briefly through the
viewing window.
1.3 Important: This product is designed to
be connected to a mains supply housed
in a dry, weatherproof enclosure.
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.
For connection to the mains supply, use
only 3-core cable (ref: HO5 RN-F). This
has a minimum copper cross-section of
0.75mm
2
with 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.
• Fitted with a 3 or 5 amp fuse.
1.4 Exposed cable runs should be sensibly
positioned, and protected if necessary
by armoured conduit, especially if they
may come into contact with gardening
equipment such as forks and
lawnmowers or children or domestic
animals.
1.5 A 10mA or 30mA Residual Current
Device (RCD) MUST be fitted to the
mains supply.
1.6 The supply cable cannot be replaced. If
the cable is damaged, the unit should be
discarded.
1.7 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.
1.8 If in any doubt about wiring to the
mains supply, consult a qualified
electrician or local electricity authority.
1.9 Protect from frost if the unit is not to
run year-round. In cold winter weather
(when fish are not active and algae
growth ceases), the unit may be
switched off. It should then be drained
of water, removed from its installation
and stored in a dry, frost-protected area
( see Winter Storage 11.0).
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
3. INSTALLATION
Installing and operating your Bioforce
12000 Filter
3.1 Important! The pump supplying this
filter should have a minimum head of
3m (10 ft; 4 psi; 0.3 bar) and a
maximum head not exceeding 6m (20
ft; 8 psi; 0.6 bar)
3.2 Protect from frost. In cold weather,
when fish and algae growth are
inactive, the unit may be switched off
(see ‘Winter Storage’ section 10.0).
3.3 The Bioforce 12000 can be installed
next to your pond or concealed at the
top of a waterfall. When positioned in
the ground, the lid band clamp should
show 25mm ( 1” ) above ground level.
Pack the hole firmly to support the
unit.
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.

3.4 Only use 40mm hose for the filtration
system. Cut 2 of the universal hose tails
(supplied) to suit 40mm Cypriflex hose.
Fit the hosetails to the inlet and outlet
connections using the ‘O’ seals and
threaded nuts supplied (see fig 2).
3.5 Push the hose from the pump onto the
inlet and secure with a hoseclip.
Connect the outlet hose in the same
way. Avoid kinks and sharp bends.
Keep hose lengths as short as possible
to minimise restriction of flow.
4. LAMP INSTALLATION AND
REPLACEMENT
4.1 Unlatch the lid clamp. Gently release
and remove the lid by using the 2
levers in opposite slots (see fig 4).
4.2 Remove the screw securing the central
tube to the lid and rotate the tube
anti-clockwise and pull to release (See
fig 8).
4.3 Remove the quartz glass tube in a
similar way remembering to remove
the screw first (see fig 9).
4.4 With the lamp holder now accessible,
push the lamp into position
(see fig 10).
4.5 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.
5. FLOW RATE
5.1 To ensure clear water, the whole
volume of the pond should pass
through the Bioforce every 1
1
⁄2 - 3
hours, the faster flow rate being
recommended for Koi ponds. Do not
exceed the maximum flow rate of 6000
litres (1300 gallons) an hour. To
decrease the flow, use a Hozelock
Cyprio flow control tap.
5.2 For the best flow and pump
performance use 40mm diameter hose.
Keep the hose short and pumping
height to a minimum.
5.3 The object of filtration is to transfer
waste material from the pond into the
filter. Choose a pump that can cope
with solids. We recommend the
Hozelock Cyprio Titan 8000 Filter
pump, which is specifically designed for
pond filtration systems. For the best
circulation of water,this should be at
the opposite end of the pond to the
return hose from the filter (see fig 1).
5.4 How to check your flow rate;
a) Take a container of known volume
(litres or gallons). Time in seconds how
long it takes to fill from the Bioforce
outlet.
b) Divide 3600 by the number of seconds
to fill the container and multiply by the
container volume. The result will be the
flow rate in litres or gallons per hour.
3600
x Container
= Flow rate per hour
Time Volume
6. PERIODS OF OPERATION
6.1 Keep the filter working 24 hours a day.
Ideally it should run all year round, but
at least throughout the feeding season,
( ie until water temperature falls below
10°C). In winter, operating the pump
and filter will maintain a basic level of
useful bacteria in the Bioforce and will
help prevent the pond icing over. If you
switch off the pump for winter, wash
the filter thoroughly before resuming
filtration in the spring (see ‘Winter
Storage’, 11.0). Never feed your fish
when the filter is not in use.
7. FISH STOCKING RATE AND
DENSITY
7.1 Under normal conditions, the Bioforce
range will support up to 50cm of fish
per 1000 litres of filter capacity (10”
per 100 gallons). Introduce fish slowly
over the first few weeks, up to 20% of
the maximum recommended level,
increasing to 50% after six months.
The balance will allow for fish growth.
8. MATURATION
8.1 Biological maturation means that the
filter has built up enough nitrifying
bacteria to convert harmful fish and
other organic waste (ie ammonia,
Nitrite) into relatively harmless nitrate.
The process normally takes 6-8 weeks
but depends on many factors such as
water temperature, feeding rate and
stocking density.
9. WHEN TO CLEAN YOUR
BIOFORCE
9.1 Bioforce filters deliver maximum
performance with minimum
maintenance. If the pond is very dirty,
the filter may need cleaning every few
days at first, as it takes up waste matter
very quickly. Once the pond becomes
clearer, there will be less waste to
remove, so the filter will need cleaning
less often.
9.2 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.
10. CLEANING
WARNING: do not attempt to remove
the lid or pressure release valve when
the pump and filter are in use. A slot
for a padlock is provided to prevent
accidental opening and we recommend
this is used where children are likely to
be present.
Thorough Cleaning
10.1 To prevent dirty water being backsiphoned through the filter and into
the pond, lift the outlet pipe above the
height of the filter lid before switching
off the pump.
10.2 Switch off the power to the pump and
Bioforce 12000.
10.3 To remove the clear viewing window
turn anti-clockwise, lift up, then turn it
clockwise (see fig 3).
Clean the viewing window and seating
area in the lid.
10.4 Unlatch the lid clamp. Gently release
and remove the lid by using the 2
levers in opposite slots (see fig 4).
10.5 Gently remove the foam discs from the
filter vessel and clean thoroughly.
10.6 Re-fit the foams ensuring they lie flat.
10.7 Re-fit 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 help assembly.
10.8 Re-fit the lid clamp. Ensure that there is
no build up of water beneath the band
clamp and keep the hinged lever
lubricated using an oil based lubricant.
10.9 Clean and re-fit the viewing window
ensuring it ‘clicks’ into the correct
position. The handle should be in line
with one of the marks on the lid (see
fig 5).
Add a light coating of silicone grease
to the seals if required to help
assembly.
10.10 Re-start the pump first checking for
leaks, then switch on the UV lamp.
10.11 Normally, there is no need to remove
the foam support plate. However, if
you need access to the bio-media under
the plate, firstly clean the foams and
empty the filter as described. Then
remove the foam support plate by
lifting it clear of the vessel with the
finger holes (fig 6). To re-fit the
support plate, the water should be at
the level shown in figure 10 with the
bio-media floating in the vessel. Make
sure you re-fit the support plate
correctly, so that pond water cannot
bypass the filter.
10.12 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).
10.13 Care of the uv quartz tube
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 4.0
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.
11. WINTER STORAGE
11.1 When not in use, the unit should be
removed, thoroughly washed and
cleaned and dried and stored in a dry
frost protected area. Always store the
unit with the lid off to ensure
adequate ventilation and drying.
