'WINTERIZING' YOUR
POOL
1. Make sure to clean the
pool as best possible by
brushing the walls & floor
& then the next day
vacuuming the pool well.
This will make sure that
there is not algae &
bacteria living in a film
on the walls & floor of
the pool.
2. Give the pool a good
chlorination to at least
10.0ppm of chlorine, do
this preferably with
calcium hypochlorite or
liquid chlorine (Sodium
Hypochlorite). Keep the
filter operating during
this period.
For each 10,000 US galls
or 40,000 liters of volume
in your pool.
If you use the calcium
hypochlorite, then use 1.5
lbs (750gms) of product &
if you use the liquid
chlorine, then use 6 US
pints (3.2 liters) of
liquid.
This will burn off any
algae spore or bacteria
which may be in the water.
The reason for using the
powder or liquid is that
both raise the pH & you
are best to keep the pH up
to about 7.8-8.0 during
winter to stop algae
growth.
3. After 24 hours, when
the chlorine level has
come down, add a good
quality concentrated
algaecide to the pool in
the dosage recommended for
winterizing on the label.
DO NOT ADD THE ALGAECIDE
WHILE THE CHLORINE LEVEL
IS HIGH.
4. If you have a cover,
then cover the pool
5. Filters & Pumps.
If you have a SAND
filter,, then give it a
good backwash while the
chlorine level is high &
this way it will kill any
algae spore or bacteria
which may be in the filter
sand. Once it is clean,
switch off the pump & if
there is the chance of
freezing, then drain the
filter tank. If you have a
CARTRIDGE filter, then
remove the cartridge &
give it a good clean &
leave it to dry in a safe
place, if there is the
chance of freezing, then
drain the filter tank.
If you have a
DIATOMACEOUS EARTH filter,
then take the tank apart&
remove the pads & give
them a good clean, scrub
them with a light brush if
necessary. Then leave them
to dry, if there is the
chance of freezing, then
drain the filter tank.
ALWAYS LEAVE FILTER
VALVES IN "WASTE" OR
"BACKWASH" POSITION SO
THAT ANY ICE FORMING IN
THE PIPES CAN EXPAND. THE
REASON THAT I SAY TO LEAVE
THE PADS OUT OF THE DE
FILTER & THE CARTRIDGE OUT
OF THE CARTRIDGE FILTER IS
TO STOP ALGAE OR FUNGUS
GROWING ON THEM WHEN THEY
ARE NOT OPERATING OR BEING
DESTROYED BY ICE.
Clean the strainer in
front of the pump to make
sure any leaves are out &
if you live in an area
where the water freezes,
then empty the water out
of the pump.
6. If you have run the
filter for the correct
time after adding the
chlorine, then the pipes
should be clean of any
algae & bacteria.
7. If you live in an
area where the water
freezes, then isolate the
pipes from the pool.
You will need to plug the
pipes in the pool with
rubber expandable plugs
available from most pool
shops. It may also be
necessary in some areas to
have the pipes drained,
you will normally need a
service to do this with
compressed air after they
have plugged the pipes
from the pool.
