are many reasons that can cause cloudy pool
• Low sanitizer level
• Combined chlorine – free chlorine combines
with contaminants, becomes used up and has very
little sanitizing abilities.
• Insufficient filtration – caused by
too small of a filter or insufficient hours
• Dirty filter – as dirt accumulates in
the filter media, water flow is restricted.
• High pH/total alkalinity – reduces the
sanitizing action of chlorine.
*Treatment: Shock the pool to increase chlorine
residual and oxidize contaminants. Adjust the
pH to 7.4-7.6. Chemically cleaning the filter
may help to resolve the problem. If your water
chemistry seems to be good, but the water is
a little hazy, try using a clarifier.
water can be green for a couple of reasons:
• Algae – Algae growing in the pool and
on the sides of the walls can cause the water
to be green and typically consumes chlorine.
Brush the walls of the pool and vacuum; add
algaccide and shock.
• Source Water – If chlorine levels are
high, another cause for green water is metals
in the source water. When chlorine is added
to the pool, it reacts with the metals and causes
a green tint. A filter aid can help to remove
these metals. Adding scale inhibitor to the
water is recommended to keep them in suspension
so they don’t damage the equipment or surface
of the pool.
in the pool can be caused by organic matter
that has settled and decomposed on the bottom
of the pool. Also, metals from the source water,
such as iron or copper, can come out of solution
and cause staining on the pool walls and floor.
If the stain is caused by organic matter, vacuum
up the debris and use the appropriate stain
removal product. If the stain is caused by a
metal, first filter out the metals and then
follow with the appropriate stain removal product.
Your local pool care professionals can help
you diagnose your particular staining problem

or reversing the water flow through the filter,
will help dislodge debris within the filter
to help keep it clean. A filter should be backwashed
when the reading on the filter’s pressure
gauge increases 8-10 psi over its normal reading.
You also may note the water pressure returning
to the pool; a decrease in pressure is an indication
that it is time to backwash.
strong chlorine smell indicates there is too
much combined chlorine in your pool and not
enough “free chlorine”. Combined
chlorine, or chloramines, is the by product
of chlorine reacting with contaminants in the
water. Chlorine gets a bad rap, but it is actually
chloramines that cause the odor and other undesirable
side-effects. Shocking will eliminate the chloramines
along with its undesirable characteristics.
pH, High pH or too many chloramines in your
pool can irritate your eyes. Adjust the pH so
it is between 7.4-7.6 and shock the pool to
Weekly maintenance includes adding tabs/sticks
to the skimmer or chlorinator to maintain a
1.5 – 3 ppm chlorine residual in the pool. Also,
adding a weekly dose of algaecide and shock
will help to keep a crystal clear pool. Brushing
and vacuuming your pool as part of your weekly
maintenance routine will greatly help to keep
your pool clean and safe—and save you
best time to shock your pool is in the evening
when the sun has gone down. Shock is unstabalized
chlorine that can burn off easily from sunlight,
even on overcast days. By shocking at night,
the chlorine is able to react with the contaminants
rather than being dissipated by sunlight. Also,
shocking in the evening usually allows enough
time for the chlorine to return to a level that
is safe for swimming by the next day. It is
best to leave your cover off for 4-6 hours after
shocking to allow the byproducts of the chemical
reaction, which are a result of shocking the
pool, to “gas off”.
bleach is 3% sodium hypochlorite, whereas Liquid
Shock is 12.5% sodium hypochlorite. Although
they are the same chemical, liquid shock is
much stronger solution than Clorox. To treat
a 10,000 gallon pool, you would need to use
one bottle of Liquid Shock; if you were to use
Clorox bleach, you would need 4 bottles. Clorox
bleach also contains added detergents, which
could interfere with the chemical balance of
