New For
2007. Cloverleaf have
scrapped their past foam fractioner bucket style design (similar to "Febi
Turbo Cleaner"), and have instead opted for a fresh radical design
approach culminating in a unit with a small footprint based on the basic
body of the M70 fluidised bed filter. Cloverleaf’s thinking process
concluded that having a device which is rich in oxygen saturated water
was a waste of resources if a substantial biological gain could not also
be made, and the new Dual Function Foam Fractioner addresses such
technical shortcomings by now incorporating a high performance
beneficial biological media bed.
The new
fractioner/protein skimmer will appeal to all those suffering foam on
the pond surface (excess protein or dissolved organic compounds), or
those pond keepers who are simply after obtaining the ultimate in water
quality via an additional contribution in reducing nitrite levels.
Key assets of the new design are superb value for money, a visual
awareness of the units internal behaviour, far more easier maintenance
of the venturi, plus the great bonus of incorporating 4 litres of long
life floating biological media which significantly enhances water
quality and the pond environment.
The new
floating plastic media is as used in Cloverleaf’s latest PSS (particle
separation system) ADTEC range of Multi Bay Filter’s which following
extensive research and development is believed to be technically
superior to anything else available on the international market. The
media was designed by Cloverleaf and is produced at the Essex factory.
The unit will cater for ponds
up to 8,000 gallons (36,000 litres) and is approx 1000mm high (40") with
a body diameter of 110mm (4").
Minimum pump requirement are 3,600 LPH (800 GPH) - ideal 4,500 LPH
(1,000 GPH). Pipe inlet size 40mm (1.5”) –
outlet 50mm (2”). Maintenance of the device is minimal.
The
basics of the devices operation is that pumped water (via a dedicated
pump) passes under pressure through a venturi unit, where the input of
air creates a large volume of oxygen rich water which passes down the
transparent column through the biological media. Once the water reaches
the base of the column its flow path is forced into an outer cavity
formed by a short length of transparent inner pipe (the collection tube) . By the laws of physics any air bubbles which have
attracted contaminants within the water then rise up into the capped inner pipe
(the collection tube), where they also rise to thereafter
discharge through gravity into the waste pipe outlet ready for
collection via a bucket or bowl (not supplied). The remaining flow of
water in the outer cavity continues its path to the main bottom outlet
where it is returned to the pond. To
cater for various pump flow rates and controlling variable waste extract
levels a standard Cloverleaf side valve is provided on the pond return
outlet. Its setting will automatically also influence the saturated
oxygen output (LPH).
Many
pond keepers believe that their current water quality is exemplary, and
become amazed when they establish just how much dirty waste matter can
be extracted from their ponds upon installing a Cloverleaf foam
fractioner (protein skimmer) type device. Beyond general contaminants,
colourants are also converted into waste, and as an end result water
clarity and sparkle is visually improved with a more healthy environment
being created.
With no
two ponds being the same it is impossible to state how much waste can be
extracted from any pond. Likewise there are no cast iron rules as to
using a foam fractioner properly. Some pond keepers will find it
necessary to have the device running 365 days a year, whilst other will
obtain adequate success in only using the device for a few days each
week after an initial dirty running in period.
The
importance of having good oxygen saturation levels in Koi ponds is vital
for the health of the fish, and of great importance to sustaining the
beneficial biological bacteria which colonise within conventional
filtration system mediums. This can be achieved by numerous techniques
including airstones, or conventional venturi units, however not everyone
wishes to having their ponds resemble a witches cauldron, and it is in
this area where the “Cloverleaf Foam Fractioner” offers a great
bonus by pumping oxygen into the water
in a subtle fashion (within the device).
It
should be stressed that the Cloverleaf Dual Function Foam Fractioner cannot be
regarded as any form of saviour to an existing pond with a poor
filtration system. This is not its purpose.
Usage
Tips:
The
control valve should be adjusted so that a slow drip pattern is seen
going into the external waste bowl. Heavy rain, water changes and
feeding the fish will have a temporary affect on reducing the drip flow
rate (perhaps to nothing), however no further adjustment should be made,
and the system should be left for normality to return.
Periodic cleaning of the Inner Perforated Transparent Collection Tube is
advised, with access available via removal of the base plant.
For vertical stability of the Foam Fractioner device the circular base
plate should be screw fixed down to a suitable medium (concrete paving
etc), or alternatively fixed to a plank of timber decking.
To
reduce surface agitation and noise the return pipe to the pond can if
required discharge via a bend and short vertical drop with the bottom of
the pipe drop set 30mm above the pond surface. All pipework should be
50mm diameter.
In the
event of using medications in the pond it is advisable to adjust the
foam fractioner so that its extract abilities are terminated, however
under such circumstances the device should ALWAYS be left running due to its
production of oxygen, and its live biological bed.

Seal Every Pond
Keeper Should Have A Tube Standing At The Ready |
|
No Need
To Drain Down Ponds Or Tanks To Fix Leaks |
 |
Cloverleaf's
fish safe Wonder Seal is a specialist formula multi purpose
waterproof sealant that can be applied under water, and can be used neat
in many instances. For rips in butyl or vinyl a clean patch of similar
material should be used as a cover strip.
Wonder Seal is
only available in a large 300ml cartridge, and seals leaks in Butyl, GRP, PVC, plastic, concrete, vinyl, glass, etc. To apply load cartridge into a standard DIY mastic gun. Seal cap after use.
Where possible protect
inpond repairs from fish attack for 12 hours, but allow 24 hours to
fully cure. By example temporary protection can be achieved on
horizontal or vertical surfaces using an upturned perforated plastic
plant container - plus weights and string as required. Long joint
repairs can be protected with a length of plastic guttering.
In all repair cases clean
the local surfaces for sound adhesion prior to applying the sealant
(using the course side of a typical nylon foam kitchen scourer, or nail
brush). Any sign of algae must be 100% removed.
Wonder Seal will
immediately stop a leak the moment it is applied, but this is not
applicable to leaks in pipes or joints carrying water under pressure.
Where patches are being applied to a leak or rip in a pond liner the
patch should receive a dob of sealant, which should be spread out evenly
(with a piece of cardboard or plastic) to give a 2mm veneer. The patch
should then be placed making sure that no air pockets exist - and then
very lightly smoothed down with the hand. Any excess sealant seeping
from the edges should be wiped away with a piece of cotton cloth. As a
guide a 50mm square patch would be ideal for a 15mm rip or hole.
Take Care: Keep out of reach of children. Irritating to eyes. Avoid contact with skin - wash off
immediately (but not using the pond as a washing bowl). Use the product only in well ventilated areas. |

Cloverleaf
"COMPLETE" fish food works great in
theCloverleaf Autofeeder
|
New For
2006. Cloverleaf past Auto
Fish Feeder range were proven to be extremely successful, but have
through redesign now become even more versatile and safer via the
introduction of the Mk3 Low Voltage models (as launched at
GLEE during Autumn 2005).
With the transformer integrated into the computerised timer the auto fish feeders are a breakthrough in both sophistication and
exceptional value for money, and will be appreciated by all pond keepers who either have frequent holidays, or by those who are away from their ponds during most of the day.
Models remain available in three
sizes - the Small PF1-LV (5 litre pellets), Medium PF2-LV (10 litre) ,
and Large PF3-LV (20 litre) , with the largest model measuring approx
530mm high x 275 dia.
The timer can be set for “minutes & seconds” (with 1 second
being the ultimate minimum), and as a consequence this makes the autofeeder suitable for the smallest of ponds. It is believed that this
facility makes the Cloverleaf Auto Fish Feeder totally unique in the
value for money stakes.
Feeding small amounts at frequent intervals is scientifically known to be the best of
techniques for the benefit of both fish & filtration systems, and the computer controller with digital display allows just this. Up to 8 feeds a day over any given period are possible, with full control over the exact amount being fed.
The quantity of pellets dispensed is approx half a cupful in 1
minute –
which as a guide represents about 2 ounces of Tetra Koi Floating Sticks.
Although the Fish Feeders
are IP55 protected the computer programmer
unit needs to be housed in a dry sheltered position. In instances where playful
domestic pets or young children have access to the pond the auto feeder
casing should ideally be fixed down to the adjacent decking/paving for
stability and security.

Cloverleaf
design and produce their own side valves based upon a sturdy cam lever
design, and these are available in 2 nominal standard sizes of 110mm
(4") and 50mm (2"), with a series of collar insert rings to
support other various smaller pipe sizes. Conventional standard models
(seen here) provide the facility for connecting pipework via adhesive
(like plumbers Polypipe). Where desired stepped hosetails can also be
directly glued into the valves. All valves provide ease of use in
changing components after being subjected to excess wear or accidental
damage. |

Cloverleaf C82 Air Pump Compressor |
 |
New For
2006. The
Cloverleaf C82 Air Pump compressor driven by an electric magnet
motor provides approx 82 litres per minute (4,920 lph) of purified
compressed air, and with its single 12mm outlet is also ideal for the
Particle Separation System (PSS) seen within the filter section of the
website. The pump is of battleship construction superbly engineered with
the heat dissipating case formed from ZL102 aluminium alloy. A non
return valve is recommended if the pump is located below the water level
of any filter.
The C82 which many
individuals will likely regard as fabulous should ideally be located in
a weatherproof air vented housing, and like all other pond related
electrical devices be protected via an RCD unit. |

Air Diffusers |

| Breif
Intro: |
|
With
countless international questions asking “why have all my largest fish
died overnight” – the wise hobbyist or pondkeeper will never become
reliant upon a small waterfall, or the agitation from a filter return
pipe being fully capable of providing quality (life saving) levels of
saturated oxygen. Consequently additional man made mechanical devices
are vitally important, especially during warm summer periods, and
especially so for those with heavy planted ponds, or those unable to add
airstones within their filter systems. (Alas, not everyone is fortunate
enough to own a Cloverleaf multi-bay system).
Fish,
and indeed the beneficial bacteria that colonise the mediums
within our filter systems demand
good levels of oxygen saturation for survival and maximum development,
and Cloverleaf duly offer a range of devices to enhance the health of all
ponds. (Air pumps not supplied).
It is an
impossible situation to visually examine fish and to conclude that
oxygen saturation levels are sufficient. Cheap test kits (as produced by
numerous companies) may not be highly accurate, but will however provide
a good indicator in highlighting potential problems. (Readings should be
taken at different times throughout the day). |

Bottom
Drain: This 100mm nominal (4”) bottom drain suitable for gravity
fed filter systems incorporates a removable dome with a large integral
surface mounted circular ring air diffuser – supplied complete with 10
metres of air tube.
For
those hobbyists who are disturbed by too much visual agitation in the
centre of the pond, then the air pump can easily be linked to a time
switch where by example it is only operational from say 6pm in the
evening around to 9pm the following day. |

|
 |
Air
Diffuser Rings: With the flexibility of being used alone, or in
groups, and offering the scope for placing anywhere on the pond floor,
these weighted air diffuser rings offer super performance whilst
providing a good life expectancy. Available in either 150mm diameter
(6”) or 250mm diameter (10”) sizes they are supplied complete with
10 metres of standard air tube. |

Venturi |
 |
Venturi:
Suitable only for a pressure pump input, and ideal for connecting to the
outlet/return on gravity fed filter systems the venturi unit is a well
establish and highly efficient device for improving oxygen saturation
levels. The sound constructed Cloverleaf Venturi is engineered to offer
the hobbyist the facility of swopping between the two different cones as
supplied, and thus provide greater control over distribution.
(Where
desired the Venturi can of course be run from a separate dedicated
submersible pressure pump) |

Vortex Bay Pump Diffuser |
 |
The
importance of obtaining a good rotational spin in a vortex bay without
disturbing particles or waste that has dropped out of suspension is a
vital requirement, and this is why on pumped supplies to multi bay
filters Cloverleaf have introduced the option of fitting a diffuser.
This simple push fit device (with facility for incorporating a stepped
hosetail pipe connector- up to 40mm/1.5”) has been specifically and
carefully designed for the task at hand. Water entering the large bore
horizontal inlet is diffused to the point of converting the flow into a
series of horizontal and vertical jets within the inlet pipe, and this
amalgamation diffuses the direct horizontal velocity flow when finally
entering the vortex. The pump diffuser is available in 3" or
4" diameter sizes.
This
device also makes a good birthday surprise present for the lady who has
everything. |
