INSTALLATION
Connecting to your pump
The ideal flow rate for your pond is to pump the volume of the pond water through the filter
every 2 hours. To calculate your pond volume: average length (m) x average width (m) x
average depth (m) x 1000 = pond volume in Litres.
To calculate your pump’s flow rate, fill a container from the filter outlet hose at the pond
side. Time how long this takes in seconds, e.g. a 10 Litre bucket takes 12 seconds to fill.
Divide 3600 (the number of seconds in an hour) by the time taken to fill the bucket,
e.g. 12 seconds. Then multiply by the volume of the container, e.g. 10 Litres.
Therefore: 3600/12 = 300, 300 x 10 = 3000L/H flow rate.
To increase flow, you may require a larger pump. If the flow rate is too high, use an inline valve
to reduce it (or use the digital control of a Blagdon Amphibious IQ pump).
The purpose of the pump is to transfer dirty water from the pond to the filter cannister.
Placing the pump at the opposite end to the filter outlet will provide the best results.
Pumps without foam pre-filters will allow for optimum filter performance.
Connecting the inlet/outlet hoses
•
Always secure the hose with a jubilee clip.
•
Warming the hose in a bucket of warm water can aid fitting.
•
Always ensure the smaller diameter hose tails are cut off and removed to prevent
poor UVC performance and flow rate from the outlet.
•
Use the shortest possible lengths of hose, in order to minimise flow restrictions.
•
Avoid folds and kinks in the hose, which will reduce flow and UVC performance.

IMPORTANT:
The outlet hose should be
smooth bore (not corrugated)
pipe installed over as short a
distance as possible, with no
kinks or bends. We recommend
that a smooth bore clear hose,
or smooth bore heavy duty
black hose are used.

IMPORTANT:
Do not exceed the maximum stated flow rate through the UVC filter –
see technical specifications table on page 4 for reference.
