Altering Chlorine output –
1. Increasing or decreasing the Salt Generator operating time: Depending on the pool and model chosen, the daily operating time
may vary from 8 to 12 hours per day. The best time to operate your system, and obtain the optimum ‘residual’ build up of
Chlorine, is in the early morning and after 4:00PM when there is less UV from sunlight to destroy the Chlorine produced.
This leaves more Chlorine in the pool to ‘oxidize’ the unwanted foreign matter in the pool’s waters.
2. Increasing or decreasing the Chlorine output percentage:
This allows for a finer control over the Chlorine level and is accomplished by turning the control knob to 100%.
3. Ensure a sufficient operating time – at least 8 hours or 1.5 turnovers.
BASIC POOL CHEMISTRY TERMINOLOGY
TDS – Total Dissolved Solids:
There may be other elements, in addition to salt, that may be present in the pool’s water. Your pool professional can perform a
TDS test, and determine if there are other elements that may be harmful in the pool water as a result of adding salt.
Combined Chlorine vs. Free Chlorine:
1. Combined Chlorine, also known as Chloramines.
Combined Chlorine is a molecule of Chlorine that has attacked a particle of contaminant in the pool water, and has
failed to destroy or neutralize the particle. This is most often associated with bad smells and other effects of Chlorine.
This Chlorine molecule has bound itself to the particle and remains bound to it until one or the other is ‘burned’ off.
This condition requires that the pool be ‘shocked’ periodically to destroy the contaminant and ‘free’ the Chlorine molecule to
assist in sanitizing the pool. This procedure of having to periodically shock the pool is an unpleasant exercise.
Installation of a Prozone Ozonator/Salt Generator System does away with this unpleasant exercise by destroying the
contaminant particles in the Salt Generator Cell, and freeing the Chlorine to return to a ‘free’ state that is then able to keep the
pool clean, clear and pleasant to use.
2. The ‘free’ Chlorine in your pool is the pure chlorine required to provide residual sanitation at all times.
Free Chlorine should remain ideally within the range of .5 to 1.0ppm. This lower level of residual chlorine is possible
because your Ozone system has the potential to oxidize and sanitize, between 60% to 80% of contaminants in the pool
water. The “free” chlorine is unnoticeable when swimming and maintains a high level of residual sanitizing power.
Water Balance:
The water balance of your pool is critical to monitoring even if you have installed an Ozonator/Salt Generator System. There are
three components – ph; Total Alkalinity; and Calcium Hardness – and each are collectively necessary in order to keep balance within your
pool’s water. Each is described below.
pH Level:
1. pH is a measure of how ‘acidic’ the water is in the pool .
2. pH is measured on a scale of zero (0) to 14 and a level of 7 is considered neutral and is generally described as being pure water.
3. A level higher than 7 is considered as reaching an ‘alkaline’ solution, and a level less than 7 is considered as going toward an
‘acidic’ solution.
4. A high pH begins to reduce the effectiveness of Chlorine, and will potentially cause scale to appear in the pool and on the pool
equipment, and also begin to irritate the bathers.
5. A low pH may cause the water to become corrosive, and damage the pool interiors finish, pool equipment (heat exchangers
especially), and also irritate the bathers.
6. Each pool finish and type has a specific range in which the pH should remain. Generally a pH of between 7.2 to 7.8 is suitable
for most pool types and optimum for bather comfort. Consult your pool professional if your pool requires higher pH and therefore
a higher Chlorine ‘residual’.
7. To lower pH a diluted solution of Muriatic Acid and water is used.
8 To raise pH add sodium carbonate.
Total Alkalinity (TA):
1. The total Alkalinity is a measurement of all the alkalis in your pool water such as Carbonates, Bicarbonates and Hydroxides,
and their ability to resist change in the pH.
2. When adjusted within the acceptable levels, TA acts as a pH buffer, resisting change to the pH. The recommended TA level
of your pool is from 75 to 170ppm depending on the pool finish. A good level would be in the 80ppm range.
