Proper care and maintenance of your vinyl pool liner will
ensure summers of memories for years to come.
We at GLI Pool Products would like to share some helpful information for
the care of your inground liner.
The first step in the proper maintenance of your inground
vinyl liner is maintaining proper chemical levels. As always we suggest having an
APSP Certified Pool Professional regularly check your pool chemical
levels, as they will know exactly what your pool needs are given each unique
backyard environment, the below information and tips are to assist you between
We suggest the following at home water testing between
regularly scheduled professional testing.
7.2 – 7.6
1.0 – 2.0 ppm
80 – 120 ppm
200 – 300 ppm
35 – 60 ppm
What is pH?
PH is the measurement of acidity in the pools water. PH is measured on a scale of 0 to 14 with 7
being neutral. A pH below 7.0 means the
water is very acidic; as the pH approaches 8.0 the water becomes very basic
(alkaline). A pH level of 7.4 is ideal
for most pools. (Fun Fact: 7.4 is the pH of human tears.)
It is important to monitor the pH levels of your pool to
ensure your vinyl liner does not become damaged. A change one way or the other can cause
substantial problems to your vinyl liner.
A pH below 7.0 causes your water to become aggressive to pipes, vinyl pool
walls and metal components in heaters, pumps and filters. All of these elements
stand the chance to corrode. Low pH water also causes skin and eye irritation,
making the eyes look red. High pH causes pool water to look dull and flat, and
also causes skin & eye irritation.
The pH of your pool water will have a significant effect on your
Daily home water tests and regular dealer water tests are
recommended. If you were to notice a pH
that is out of the suggested range you should immediately contact your local
pool professional for assistance.
All pool owners know the importance of chlorine. Chlorine is a chemical most often used to
keep swimming pools free of bacteria that can be hazardous to humans. Currently the industry standard for chlorine
levels is between 1.0 ppm and 2.0 ppm.
Daily testing and monitoring of your chlorine levels will
ensure that your pool maintains a stable level of chlorine; you will want to
especially monitor these levels after heavy rainfalls. The sudden increase in water to the pool can
cause your chlorine levels to fall below the recommended range, potentially
leading to algae & bacteria growth and staining, if the chlorine is not
adjusted. At the same time, you want to
be sure your chlorine levels do not exceed 2.5 ppm. As always, when in doubt contact your pool
The total alkalinity (TA) is the measure of how much
alkaline substances there are in the pool water. With swimming pools, the main concern is
bicarbonate alkalinity, which should be between 80 – 120 ppm. When the TA falls between this range it helps
to “stabilize” the pH level and prevent rapid changes to the pH. In short, TA
is a measure of how resistant to change your pH levels are.
It is recommended that you test your pools TA levels at the
very least weekly and if they are outside the recommended range you contact
your pool professional for directions on a process to correct this issue.
Well we’ve all seen and/or heard of calcium build up within
our home water lines, it is also important to monitor within your swimming
pool. Water hardness consists of both
calcium & magnesium salts; only the calcium component is relevant to
swimming pool water balance.
The effects of high & low hardness can cause some ill
effects on your swimming pool. High
calcium hardness causes cloudy water, rough surfaces, clogged filters &
circulation and heater inefficiency, while calcium hardness that is too low
causes pitting of concrete pool services, etching of plaster, and dissolving
grout. Keep your calcium hardness
between 200 – 300 ppm to avoid any ill effects to your pool.
If you have questions regarding your pools
chemistry speak to your pool professional or visit APSP.org. The above is
intended to provide an overview of information and nothing can replace the
1-on-1 assistance your pool professional can provide.
Allow chemicals to circulate through the pool
and do not add more than one chemical at a time.
Do NOT use abrasive household chemicals on your
liner. Take special care to clean the
area above the water line regularly to prevent fading from the sun & UV
Clean your pool regularly. GLI’s Dirt Devil Robotic pool cleaners can
help cleaning the entire pool without connecting to your pools filtration
system, as they work independently.

Properly covering and winterizing your swimming
pool in the fall can help extend the life of your vinyl liner. Visit here to see GLI’s line-up of Safety Covers
that can provide you both the best in winter safety and ease of spring cleanup.
