There are three important reasons
to sanitize your pool:
1. Health–topreventthespreadofinfectionanddisease
2. Safety – pool water must be free of cloudiness to
contribute to water safety and the bottom of the pool
should be visible at all times
3. Aesthetics – because there’s nothing like a sparkling
blue, crystal clear pool
Symptoms of overstabilization:
• Cloudywater
• Highchlorinereadingwithalgae
• Addingchlorinedoesnotremovealgae
Choosing a Sanitizer
HTH® Pool Care offers two types of chlorine-based
sanitizers: stabilized and unstabilized. Stabilized
chlorine contains cyanuric acid/stabilizer, which
shields the water from chlorine degradation caused
by the sun’s harmful ultraviolet rays. Unstabilized
chlorine does not contain cyanuric acid/stabilizer and
may degrade more quickly from ultraviolet rays if it
is not used in conjunction with cyanuric acid in the
pool. If the cyanuric acid/stabilizer levels are too high
in your pool water, overstabilization or chlorine-lock
can occur.
Yellow HTH sanitizers will not cause overstabilization.
The HTH 3-in-1 Chlorinating Skimmer Tablets
dissolve slowly and are for use in skimmers, whereas
the HTH Chlorinating Granules can be broadcasted
directly into the pool or through the skimmer.
HTH Dual Action 3”
Chlorinating Tablets
•Protectsagainstbacteriaandalgae
•Sunprotectedforextendedchlorinelife
•Availablein1”and3”tablets
We recommend using HTH Stabilizer & Conditioner
with our unstabilized (yellow) chlorinators. Always
add this product before you add sanitizer. Allow at
least 48 hours for the stabilizer to dissolve.
HTH stabilized sanitizers/chlorinators are sun-resistant
for extended chlorine life during hot summer months.
The tablets are designed for use in skimmer baskets,
floaters or feeders for long-lasting chlorination.
If you are using HTH Dual Action Chlorinating
Tablets, HTH Metal Control should be added weekly
as part of your regular pool maintenance routine.
What is overstabilization?
Excessiveamountsofstabilizercancauseoverstabilization.
This is the buildup of cyanuric acid in your swimming pool
water resulting from the use of stabilized sanitizers and
stabilized shock products. Overstabilization significantly
decreases the effectiveness of chlorine in killing germs,
bacteria and algae. Note: Overstabilization can happen
in less than one season.
