When choosing a
and filter system it is best
to find out
first how many gallons of
water you will be moving and cleaning.
Rule of thumb is to circulate the entire body of water at least
once every two hours. So, a pond containing about 2000
require a pump
capable of pumping 1000 gallons per
a pond containing 1000 gallons will require a pump capable
of moving 500 gallon per hour and so on... This
considered the minimum size pump you will need. If you
intend to pump the water
up and out of the pond in order to
supply a waterfall
feature then a larger size
pump may be
Simply pumping the water should not be confused
with filtering the water.
Your choice of
is important and will affect your choice of pumps. For example,
constructed of rubber liner holding 2000 gallons feeding
a bio-falls waterfall located 15 feet away and a
couple of feet
higher than the pond would best be teamed-up with a skimmer
filter-box and 1500 gallon per hour
high volume waterfall pump.
A smaller 500 gallon pond
containing no fish and using a
spitting frog for
circulation and aeration might only require a
and filter kit .
While both system types are effective each is customized to
the size of the pond and where the water is pumped to and for
what purpose. Skimmer
systems are definitely easier to clean
and maintain and they provide excellent,

provide a reservoir in which course
collects debris and houses nitro-fine
bacteria. This bacteria
cleans the water. Skimmers typically utilize a powerful waterfall
pump which must be removed
during winter due to the
position of the skimmer-box at the top edge of the pond where
is inevitable. In this case a winterizing mechanical-system
would be used in the winter months

These systems are convenient due to the
fact that they

even a table top dish fountain..
pumps are also more repairable due to the
that they only have one moving part the
The impeller is easily
replaced if it breaks.
In general it is wise
to figure out what the appropriate size pump is for the gallons
in your pond and then purchase the next
two larger to ensure adequate circulation even if the
become over soiled.
NOTE : Only clean the water in the pond ...
NEVER scrub the inner walls of your pond.
The slippery, fuzzy growth on the inside surfaces
contains beneficial nitro-fine bacteria and actually
help to promote water clarity. Cleaning the inside of
your pond is like starting fresh. Starting a new pond is
definitely more work than correcting and existing problem.
You should never
change all the water at one time.
Rule of thumb is about a third can be replaced
harming fish or plants. Testing water after is important
to keep salt levels, chlorine levels and ph in balance.
