runs) it may be necessary to adjust the
flow to achieve the 1 1/2 - 3 hour
turnover rate using a Hozelock
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 object 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 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 plastic
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 there 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 foams 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 discs 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 biomedia 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
bayonet 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.
