Connecting To Your Pump
The pump supplying the Minipond filter must not have a pumping head exceeding 4m - 0.4 Bar.
The maximum flow rate recommended is stated in the filter performance and specification chart.
This flow should not be exceeded.
The ideal flow rate for your pond is to pump the volume of the pond water through the filter
every 2-4 hours. To calculate your pond volume: average length (m) x average width (m)
x average depth (m) x 1000 = Litres Pond Volume.
To calculate your pump's flow rate, fill a container from the outlet hose of the filter at the pond side.
Time how long this takes in seconds e.g. a 10 ltr bucket takes 12 seconds to fill. Divide 3600
(the number of seconds in an hour) by the time it takes to fill the bucket e.g. 12 seconds.
Then multiply by the volume of the container. e.g. 10 ltr. Therefore - 3600 ÷ 12 = 300 seconds
300 x 10 ltr = 3000 ltrs per hour flow rate.
To increase flow you may need to get a larger pump. If flow is too high use an inline valve
to reduce it.
The purpose of the pump is to transfer dirty water from the pond to the Minipond filter.
Placing the pump at the opposite end of the pond to the filter will give the best results.
Foam-free pump designs will give optimum Minipond filtration.
We recommend Blagdon Pond Pumps for fountains, filters and waterfalls.
UVC Bulbs & Quartz Sleeve Maintenance
The UVC bulb must be replaced yearly. It is recommended that the bulb is replaced and
reconnected in the spring.
The Quartz sleeve can become coated in lime scale build up in hard water areas.
This should be carefully removed from the quartz sleeve with a soft cloth.
Remove the quartz sleeve from the unit and soak for 3 hours in Pump Cleaner,
ensuring that all O-rings are checked and replaced, if necessary.
A wet test must be carried out after maintenance to ensure there are no leaks before the UVC is
reconnected.
Wet Testing The Filter
IMPORTANT: A wet test of the filter under operating conditions must be carried out before
the UVC or electrical supply is installed. Connect the filter to the pump following all installation
instructions. After running for 24 hours check for leaks.
