Looking for a pump for your pond?
Choose your pond
pump wisely!
Spring will be here soon, and many of you will either be looking
for a pump for your pond, or be looking to replace a
non-functional pump.
The pump is one of the most important features of a pond,
because without a pump, there will not be any trickling or
moving water, and you will effectively have a bog. If you choose
the wrong pump, your water will either not flow the way you
desire, or you may have insufficient flow to filter your water
and/or feed your waterfall. Therefore, it is worth taking the
time to choose the proper pump to suite your needs. The first
question you should ask yourself is: "What functionalities do I
require from my pump?" Are you using your pump to drive a
waterfall? Do you have a statue? Or do you need a pump to
circulate your water and drive a filter?
Many people require a pump merely to circulate and filter their
water. It is recommended that you circulate your pond water at
least twice every hour to ensure that mosquitoe larvae do not
accumulate in stagnant water. Thus, you should measure the
number of gallons in your pond and obtain a pump that pumps at
least twice that volume every hour (I.e. the gallons per hour
rating, or GPH, should be twice that of the pond volume). If
your pump needs to feed a biological and/or mechanical filter
(E.g. submersible, pressurized, and above-ground filters), make
sure that you consult the manual for the filter to determine the
minimal required water flow to run the filter.
You will need to increase your pump rating to accommodate both
fish and waterfalls. Calculating the proper pump for waterfalls
is a bit trickier, because waterfall pumps are rated by both GPH
and maximum waterfall height. To estimate your waterfall's
height, you must measure the vertical height from the top of
your pump to the top of your waterfall or stream. In addition,
you must add another foot of height or lift for every 10 feet of
hosing you will be using (to account for loss of volume from
hose resistance). The general rule of thumb is that each inch of
width of the channel will require an extra 100 GPH. For example,
if your stream or waterfall spillway will be 10 inches wide, you
will need a pump that generates an additional 1000 GPH of flow
at your waterfall's height. One affordable line of pumps that we
recommend is the
Algreen MaxFlo line of waterfall pumps. These pumps (rated
at 2200 GPH and 3170 GPH) are powerful submersible units that
can fit into any skimmer.
If you wish to feed water into a statue or fountain, you will
need a smaller pump that has a large head (I.e. maximum pumping
height), and preferably an adjustable flow control. The highest
quality pumps that we have found are the SICCE magnet-driven
statuary pumps. These pumps have a built in sponge filter,
vibration-damping rubber pads that allow them to run in absolute
silence, suction cups at the bottom to increase their stability,
and variable flow-rate adjustment knobs. The
SICCE statuary/fountain pumps vary from 60 GPH up to 468 GPH
and can generate maximum heights of up to 7' and 4"". The
various models in the SICCE line include the Extrema, Irda,
Nova, Micra Plus, Micra, and the Mi-Mouse.
If you have multiple pond considerations, or you're not sure
which pump to choose, you can always go with a multi-purpose
pump. Magnet-driven multi-purpose pumps usually come with
mechanical pre-filters to trap large debris, variable flow
control, built-in fountain with various fountain heads, and
diverter values to allow you to split your output flow into
multiple devices (E.g. watercourses, statues, and larger
external filters). Several examples of multi-purpose pumps
include the
Shott Nursery Pro,
Algreen SuperFlo, and the
Algreen UltraFlo.
Before you start building your pond, you should take the time to
consider the many pump options available. Make sure you shop
around to find the most affordable and the most effective pump
to meet all of your requirements.
