Filter selection
|
|
To choose the ideal filter for any pond you must
first know the correct flow through the filter to maintain ideal water quality
for your pond. (Please remember that the pond size alone
does not determine the filter or pump size without first taking into account the
many environmental and physical factors)
3 ways to get help
to establish flow
-

e-mail help forms and let us do all the calculations for you
-
Give us a call 1800 607 388 for expert
advice
-
Do it yourself and use our quick reference
flow calculator for rough
estimate
-
Step one: Establish the
required flow through the filter keeping in mind waterfall** height if any, or
long hose**
-
Step Two: Choose a filter from the chart below (Example if your pond
requires a flow through the filter of 2,400 litres per hour, the Minipond 6000
would give the best result)
-
Step Three: Choose a pump, they are listed below in order of quality and
suitability

What makes a pump that is
specifically designed for sending water to a filter (such as the pumps
above) superior to a multi purpose pump such as Pondmate or Hydrapond.
1) The cage design is turtle shell shaped to attract solids from 360
degrees 2) These pumps are intended to run 24/7 year after year
3) They have a vortex impeller capable of handling solids without blocking

**Special
note, if using a waterfall or a long hose between pump and filter the pump
will need to be larger to allow for the reduced flow caused by the
head (pumping height, and/or hose length) If in doubt

***Special note, if using these
pumps, a water release kit may be required. So if in doubt please call us on

 Aussie's
additional thoughts
Tip 1: When calculating flow, always allow about
a 15% flow loss
Tip 2:
Place the pump at the opposite end of the pond to the water return, and in the
deepest part of the pond
Tip 3: Interpet offer a
chemical to prime filter systems, a great way to hasten biological activity
Interpet Bio start
Tip 4:
If in doubt always choose a pump with less than the
maximum recommended flow Within
reason the slower the water passes over the UV lamp and through the filter the
better the result. However, you can never have too much
pond flow, so, by having a slightly oversize pump and
releasing water directly back into the pond or on to a feature or waterfall through a "Tee"
with a flow valve, added
circulation is provided for the pond.
