line cracks which may develop over
a period of time are not uncommon.
They only penetrate the gel coat and
do not effect the pool's structure
or result in leakage. Scratches and
hair-line cracks are repairable. Contact
your fiberglass pool dealer for more
information. Most of the dirt and debris
that sinks to the bottom of your pool
can be brushed toward and into the
main drain and will be trapped in the
filter. Heavy amounts of dirt and debris
should be vacuumed out.
Hydrogen (pH) is
the relative acidity or base
of your pool's water. For example:
low pH would be acidic and
high pH would be base. The
human tear has a pH value of
7 and is classified as neutral.
The ideal pH value for your
fiberglass pool is 7.2 to 7.4.
pH levels should be checked
Alkalinity (T.A.) is
composed of the minerals in
your pool water that buffer
pH and is measured in parts
per million (1 P.P.M.= 1 part
per million parts of water).
If the mineral levels are too
high, then the pH will constantly
drift up. If the mineral levels
are too low, the pH will drift
down or fluctuate. The proper
total alkalinity level for
your fiberglass pool is 70
to 80 P.P.M. and should be
Hardness (C.H.) is
the relative hardness of your
pool water, and is measured
in P.P.M. If the water is too
soft, it will be aggressive
and erode pool equipment such
as heaters, ladders and even
the gel coat finish. If the
water is too hard, deposits
will form on the pool equipment
and finish. 300 to 350 P.P.M.
is the proper hardness for
your fiberglass pool and should
be checked weekly.
Dissolved Solids (T.D.S.) are
the sum total of all materials
in solution in your pool water,
and is measured in P.P.M. TDS
should be checked annually
by a pool store professional
or service company. TDS. above
1,500 P.P.M. reduces sanitizer
effectiveness and causes the
water to become abrasive. Note:
During periods of heavy rain
or high swimmer loads, all
of the above water chemistry
valves, except T.D.S. should
be checked more frequently.
tests show all the above water chemistry
items to be within the recommended
ranges, it is in balance. Balanced
water will be clean, clear, blue
and sparkles. Eye and skin irritation
will be reduced, and pool equipment
and gel coat surface life will be
extended. Balanced water improves
sanitation effectiveness and reduces
or eliminates the necessity of adding
costly water chemistry supplements.
Prolonged improper water chemistry
and high sanitizer levels can lead
to pool equipment and gel coat damage
which may not be covered by your
fiberglass pool warranty.

pool normally should be done by professional
installers, but many people have done
the installation them selves.
