Phosphates - EcoSmarte Pool System Manual

Phosphates

Will fertilize your pool
The proper procedure for using
aluminum sulfate on phosphate
removal when levels are over
1000 is as follows:
The pH must be at 7.4 or
higher. Add 5 lbs of aluminum
sulfate per 10,000 gallons of wa-
ter. Recirculate the water for 2 to
3 hours. Allow the pool to settle
(approximately 18 to 36 hours).
When the water is clear, vacuum
to waste, and rebalance your
pool. This procedure will knock
the phosphates down to about
200 ppm, so Phos Free will still
need to be added when rebalanc-
ing.
Phosphates typically come
from fertilizers in a variety of ways.
They can be tracked into the pool
by walking across a chemically
treated lawn. They can blow into
the pool from an airplain that is
spraying a farmer's field. With
Phosphates over 2,000 ppm - Step 1
Procedure for aluminum sulfate removal:
pH must be 7.4 or higher
Add 5 lbs aluminum sulfate per 10,000 gallons of water
Let pool run in recirculate mode for 2 to 3 hours
Shut the pool off and allow it to settle until water is clear (18 to 36 hours)
Vacuum pool to waste
Add liquid phosphate remover to get them to zero

the recent softened restrictions
on water quality, phosphates can
even be found in your water sup-
ply that is refilling your pool. In
recent years, the new "clear air
act" has changed air quality re-
quirements for burning coal and
refining petroleum.
Phosphates will create all
kinds of issues for the pool that
may seem unexplainable. Signs of
phosphates in your pool include
murkiness that won't go away,
fluorescent green water, and al-
gae blooms that come and go.
Phosphates act as a food
source for algae and will counter-
act all known sanitation methods.
They also tend to load in certain
types of medias, like Zeolites, and
can be very troublesome to re-
move. If you can locate the source
of them, you have a chance of be-
ing able to eliminate them.
If phosphates are found in
your water supply, a carbon filter
on the end of the hose will keep
them out of the pool. When lawns
are being sprayed, avoid wak-
ing on the grass, and cover your
pool.
Whether your pool uses
conventional chlorine or an alter-
native sanitizer, you must confirm
phosphates at zero. There are
two methods of removing phos-
phates from the water based on
the level found. Phosphates are
measured in parts per billion. At
1000 or less, a product like Phos
Free will work on them. If they
are over 1000, then aluminum
sulfate will be required to knock
them down to a level where Phos
Free will work.
