Even
if Salt Water Pools use Chlorine. They use an electronic process to create
Chlorine from Salt Sodium Chloride It is extremely important to maintain a
consistent level of chlorine in the pool. If the chlorine level is allowed to
drop to zero, the pool will develop algae the water will turn cloudy and
swimmers will be at risk of infection from bacteria and virus. The purpose of
the chlorine is to burn up (oxidize) the algae and kill germs and bacteria.
Important Terms to Remember:
Chlorine Residual - the level of chlorine in the pool water, ready to fight
germs and kill algae. This can be measured using a good chlorine test kit or
test strips.
Chlorine Demand - the amount of chlorine that is needed to burn up all the
contaminants in the water. A heavily used pool will have a high chlorine
demand and will use a lot of chlorine. A lightly used pool will have a low
chlorine demand. Properly estimating chlorine demand is very important
because if you do not, your pool will either run way to high or way too low on
chlorine.

Your Innovative Salt Water Chlorinator
Salt
Pool water chemistry is slightly different from normal pool chemistry. For
more information on how a salt system works read the salt systems section.
For information on how to work with a salt system read more below.
Properly controlling your salt-water chlorinator.
There
are three things that are important when using salt-water chlorination:
1.
Keep the proper level of salt and stabilizer in the pool.
Your
Innovative salt-water chlorinator requires 3000 - 3500 parts per million
salt. This can barely be tasted in the water, but provides enough salt for
the salt cell to produce the chlorine needed to maintain the pool.
If the
salt level drops too low, the system will not be able to produce chlorine.
Your Innovative Salt Chlorinator will show low salt levels in the pool by
turning on the Low Salt LED. The answer to low salt levels is to add low
calcium salt pellets to the skimmer and let it dissolve into the water.
It is
also important to have a good stabilizer level (30 - 50 ppm) in the pool or
the sunlight will burn up the chlorine and the chlorinator system will not be
able to keep up with the demand.
2.
Adjust the output run time percentage on the LED indicator on the Innovative
Chlorinator.
The
salt system has Increase and Decrease buttons that control the percentage of
run time and therefore the amount of chlorine that is generated. This can be
adjusted using the Increase and Decrease buttons to keep the production of
chlorine in line with the demand.
3.
Keep a close eye on the stabilizer and salt levels in the pool.
These
levels must be carefully maintained. If the salt level is too low, then the
unit will not produce chlorine. If the stabilizer level is too low, the
chlorine will not stay in the water long and the unit will not be able to keep
up with demand.
4.
Make sure the pool is running long enough to produce adequate chlorine.
The
timers on the pool should be set to run during the hottest daylight hours,
preferably from at least 8 am to 12 pm and again from 6 pm to 10 pm during the
summer. The system will only produce chlorine while the pump is running so it
is important to run the pool long enough. The Innovative Chlorinator Product
line produce 33 grams of pure chlorine per hour. This is up to 40% more
Chlorine output than most other chlorinator brands on the market. A 2-speed
pump will allow you to filter for long periods during the day while saving up
to 70% of your electrical costs. All Innovative Pool Products control panels
can be used to control 2 speed pumps and in many instances will qualify for a
REBATE from the utility company.
Shocking a Pool (Superchlorination)
If the
chlorine reading gets too low your water will not have the sparkle and clarity
you would like, it is important to superchlorinate the pool in order to
quickly raise up the chlorine level to avoid unsanitary water. The salt
system should be sized to provide sufficient chlorine output, but in the event
of very heavy chlorine demand (swim party, heavy rains, etc.) it might be
necessary to supplement the chlorine feed with a manual shock. Turn the
chlorinator output level to 100% and increase your filtering time to super
chlorinate your pool. REMEMBER to reset you output level to it is normal level
and return your filtering time to itís normal setting after your water clarity
and chlorine level improves.
Simply
adding more salt to the system WILL NOT be enough to solve the problem if you
have a low chlorine level.
Benefits of Salt Water Pools
Salt-water pools used to be the exception, but now they are becoming a widely
accepted method of water treatment in swimming pools. A many builders are now
making salt water systems standard on their new pools.
What is the cost benefit of a salt-water pool?
Most
people buy the Innovative Salt Water Chlorinator it for the increased swimmer
comfort. The mild saline solution in very gentile on your eyes and skin. It
also will save quite a bit of money on pool chemicals with a return on your
investment in 2-3 years.
If you
are going to spend $25,000 and up to build a beautiful pool, doesn't it make
sense to invest in the water quality and comfort. After all, shouldn't the
best thing about the pool be the water? In the end, (if you bought our
Innovative Salt System) you made an excellent investment on your swimming pool
experience. A little money spent on your salt water system will allow you to
enjoy your swimming experience so much more.
Is
there a down side to a salt-water pool?
The
only real problem we have seen is the fact that it does change the way you do
your water chemistry and people are sometimes slow to adapt. It is very
important to follow directions carefully with regard to water chemistry. Some
pool owners have experienced problems trying to keep the pH down, but in our
experience it is simply a matter of keeping up with the water chemistry and
not letting the pH get too high before trying to adjust it. Overall, the
water chemistry does get easier, but there is a small learning curve.
Salt Water Pools - What's Different?
What's
the difference between a saltwater pool and a pool maintained with packaged
chlorine?
Salt-water pools used to be the exception, but now they are becoming the
preferred method of water treatment in swimming pools. Many builders are now
making salt water systems standard on their new pools. Most equipment
manufacturers have also become aware of the fact that salt-water pools are not
a passing fad. They offer significant benefits, comfort and cost savings.
Lower Chlorine Levels
Saltwater Pools - 0.5 to 1.0 ppm chlorine
Traditional Pools - 3.0 - 10.0 ppm chlorine
No "Chemical Bath" Feel
NO
packaged chlorine needed.
NO
algaecides needed
NO
soda ash or baking soda
Swimmer Comfort
By
eliminating the need for the harsh chemicals, you eliminate the source of the
irritation that plagues swimmers in most pools. No more red eyes and bleached
swimsuits.
Controlled Stabilizer Levels
If you
are using chlorine tablets, you are adding 1 lb. of stabilizer for every 2
lbs. of tablets you put into your pool. Your stabilizer level rises to over
100 ppm and your chlorine becomes ineffective and yellow algae and poor
sanitization results.
With a
salt system, you add stabilizer as needed and are able to keep the level low.
Your chlorine remains VERY effective and you need much less in the water to do
the job (see above).
Superior Algae Control
Saltwater pool systems virtually eliminate algae problems. This is because
high stabilizer levels do not inhibit the chlorine in the pool.
How Does a Salt Water Pool System Work?
Salt
systems have three main components.
Salt
The
first component is plain old salt. We suggest that you purchase a low calcium
salt from your local pool supply store. You have to have a minimum level of
about 3000 parts per million of salt in the pool water. Salt makes the water
conductive so that the electricity can pass between the plates in the cell.
If the salt level goes too low, then the chlorine production simply stops
(YOUR LOW SALT LED WILL LIGHT). Salt is also the raw material from which the
chlorine is produced.
Controller
The
control unit sends power to the salt cell. The unit controls how much
chlorine is produced by regulating how long the power is applied to the cell.
If you turn the output down to 20%, then the unit will apply power to the cell
only 20% of the time, thereby producing less chlorine. If you turn the output
up, then the unit would apply power to the cell for a longer period of time.
The amount of power applied to the cell does not increase or decrease.
The
control unit will sense the level of salt in the pool and indicate the need to
add more salt. The Low Salt LED will turn on or Flash.
The
Innovative Salt Chlorinator is Self-cleaning, this feature reverses the
polarity of the voltage through the cell in order to clean any scale buildup
off of the cell plates. The Cell housing is clear and a visual check of the
cell will show any calcium build up that has not been eliminated by the
self-cleaning feature. Occasional cleaning of the cell in a 20% acid and water
solution will clean any additional calcium build up off of the cell plates.
Salt Cell
The
salt cell is a series of titanium plates with a proprietary coating. An
opposite electrical charge is applied by the controller to each plate of the
cell. As the water passes between the plates, electrolysis takes place,
releasing the chlorine in the salt.
Choosing a Salt Water Pool System
Once
you have decided to convert your pool over to salt water, you have to find the
system that is best suited for your pool.
There
are several issues to consider:
1.
Find a brand that you are comfortable with.
Look
at the control box. Are the controls easy to read? Is the controller simple
to understand and adjust? Is it weatherproof?
Do the
controls give you enough information to be able to easily diagnose any
problems?
2.
Find a unit that will produce enough chlorine.
Make
sure that it will be able to handle your pool's chlorine needs even during
times of highest usage. Most manufacturers do not tell you how much chlorine
their systems generate per hour, some systems that claim to be sized for pools
up to 40,000 gallons only make 23 grams of chlorine per hour. Our system which
is also sized for a 40,000 gallon pool makes 33 grams of chlorine per hour.

Make sure your pool equipment is compatible with a salt system.
Most
pool equipment is compatible with salt, but there are a few pieces that are
not. If in doubt, check with the manufacturer of the equipment to see if your
pump, filter and heater are compatible. Some warranties may be voided by the
installation of a salt system. In particular some heaters and newer stainless
steel filters are not designed for use with a salt system. The older
stainless steel filters like Swimquip DES series filters handle salt just
fine, but the newer Pentair NS stainless steel filters can develop corrosion
issues quickly and the manufacturer will not warranty it.
NOTE:
Technically water is not officially considered to be "salt water" until you
reach a threshold of 6000 ppm salt. Up to that point it is considered to be
"fresh water", but the salt in the water even at 3000 ppm can accelerate
corrosion in some situations.
Troubleshooting Salt Water Pools
Saltwater pool owners are generally a very happy bunch, but occasionally
things go wrong. When this happens, it usually boils down to a few basic
issues either with the salt system or with the maintenance procedures.
"System does not seem to be producing enough chlorine"
1.
Check the salt level in the pool.
Check
your salt level with a saltwater test kit (even if the system does not
indicate low salt).
NOTE:
If the system indicates a low salt level, be sure to test it with a salt test
kit before adding salt. If a salt cell is failing or is scaled it may give a
false low salt indicator.
2.
Check the stabilizer level in the pool.
The
purpose of stabilizer in the water is to help keep the chlorine from being so
quickly dissipated by UV rays. If there is not enough stabilizer in the
water, then the pool will use chlorine at a rapid pace and the salt system
will not be able to keep up. Salt water pools should have 60-80 ppm
stabilizer (cyanuric acid).
3. Check the settings on the control box
Make
sure the system settings are correct. Your Innovative Salt System can be set
to run anywhere from 0 to 100% of the time. If the pool is not using a lot of
chlorine (such as in the off season), the system setting should be lower. If
the pool is using more chlorine, the system setting should be higher.
NOTE:
Do not set the control box any higher than necessary. Salt cells have a
limited lifespan and if you constantly run the system at 100% you will end up
with premature cell failure.
3.
Check the timer settings on the pool.
The
system will only produce chlorine while the pump is running. If you have the
system set at 100% and it is still not producing enough chlorine, then it
might be necessary for you to run the pump longer.
"I
added salt, but the low salt indicator is still on"
Check
the salt level in the pool using a salt test kit (as described above).
If the
salt reading is OK according to the salt test kit, then inspect the cell. If
there is scale on the plates of the cell, then soak the cell in a 20% acid
solution.
"The
pH level seems to be going up out of control"
Check
the salt level in the pool using a salt test kit (as described above).
If the
salt reading is OK according to the salt test kit, then inspect the cell. If
there is scale on the plates of the cell, then soak the cell in an acid
solution according to manufacturer's instructions.
Salt
Water Pool System FAQ's
Is
this like swimming in the ocean?
No,
the ocean has about 20,000 parts per million (ppm) of salt in the water, while
a saltwater pool has only about 3000 parts per million salt. At 3000 ppm, you
generally cannot even taste the salt. Any water under 6000 ppm is still
considered fresh water. Your eye contains about 9000 ppm salt.
Is the
pool water still blue?
Yes,
since the salt water system creates chlorine, the water is still blue and also
very clear. A salt system gives your pool the best water quality you have
ever seen.
Can I
install it with my existing pool equipment?
Yes,
since the water is still considered fresh water, it is compatible with all
standard pool equipment (pumps, filters, heaters, poolsweeps, etc.) If you
have a stainless steel filter, check with the manufacturer. To our knowledge,
the newer Pentair Nautilus Stainless Steel filters are the only ones not
compatible with salt systems.
Does
this soften the pool water?
Yes,
and this is another benefit of the salt system. Many pool owners appreciate
the soft feel of the water.
Where
does the salt go?
We add
granulated salt (looks a lot like table salt, but without any additives) to
the pool according to manufacturers instructions. Most manufacturers
recommend pouring it into the deep end of the pool, but read your directions
carefully. The salt quickly dissolves in the pool water.
Will I
save money?
The
fact that you do not have to use packaged pool chlorine will save a
significant amount of money in the long run. The REAL REASON to go with a
saltwater pool system is because of the fantastic water quality. The money
savings is just icing on the cake.
Sizing
a Salt Water Pool System
What
size salt-water pool system should I purchase?
Each
system will produce a certain amount of chlorine per hour. If your system is
not producing enough, it may require you to run the pool system longer hours
in order to keep up with the chlorine demand of the pool. This can add
significantly to the cost of pool operation. If in doubt buy a larger system
than you feel you need.
What
is Ozone?
Ozone-
Ozone is a very powerful oxidizer that is often used in pool sanitation
however Ozone generators alone leave no residual oxidizer in the pool water.
Ozone dissipates within a few minutes of reaching the pool water. Ozone used
in conjunction with your Innovative Salt Chlorinator will allow you to reduce
the run time percentage of your chlorinator by oxidizing the organic nasties
in the water passing through the filtration system. All of the chlorine
produced by the chlorinator ends up in the pool as Chlorine Residual.
Chlorine - Introduction
Chlorine is one of the most important chemicals as far as swimming pools are
concerned.
What
is the Purpose of Chlorine?
As an
oxidizer, chlorine literally burns up organic material in the water. This is
important because by burning up that material, it greatly reduces the load on
the filter.
As a
sanitizer chlorine kills germs in fairly short order, usually milliseconds.
This is important because if the germs are not quickly, then swimmers can
become infected.
How
Much Chlorine is Necessary?
It is
important to maintain a chlorine residual in the pool water at all times. A
chlorine residual is the chlorine that is in the water waiting to oxidize or
sanitize the bad stuff. Generally speaking, you need to keep between 2.0 and
4.0 parts per million of chlorine in the water. This requires that chlorine be
added to the pool on a regular basis in order to maintain the proper chlorine
level.
How do
I Maintain Proper Chlorine Levels?
To
maintain proper chlorine levels, there are three steps:
1.
Test Regularly - this can be done using a simple test kit or test strips. We
recommend testing the water chemistry at least once per week and more often
during times of heavier usage. Follow the instructions that come with the
kit.
2.
Adequate Filtration- Your pool needs to filter enough every day to filter all
of the water in the pool one time per day in the winter or off season and
twice per day during the warm summer swim season.
3.
Superchlorinate as needed - there are several instances in which it is
important to superchlorinate (shock) a swimming pool.
If the
chlorine reading gets too low then it is important to superchlorinate the pool
in order to quickly raise up the chlorine level.
If
algae develops, it is a good idea to temporarily raise the chlorine level to
10 ppm and brush the entire pool down to expose the algae. If alge continues
to be a problem have your pool water checked for Orthophosphates.
Orthophosphates are basically a fertilizer for algae that will cause an ialgae
bloomi in your pool even if chlorine levels are high. Your local pool store
will have additives that will remove the Orthophosphates from your pool water
and return your pool to a sparkling water pool.
After a heavy rain, if a lot of rainwater and other contaminants have
washed into the pool, it is a good idea to shock the pool.

There are other sanitizers on the market, but we have found chlorine to be the
most cost effective strategy available for the homeowner today. Bromine is
often used on spas, but it still contains about 30% chlorine in the tablet and
there are issues of corrosion on outdoor pools caused by the hydantoin
(ammonia) base in the bromine tablets. Biguanides are also another option,
but most of the time we hear about people who got tired of spending the bucks
on biguanides and were looking to get back to chlorine (making the conversion
back to chlorine is not easy
Chlorine Testing
There
are two ways to test for chlorine in a pool or spa. You can use either a test
kit or test strips. Typically, test kits provide more dependable readings.
Test strips can give a quick overall test, but are not as precise and can be
sometimes confusing to use.
As
always, read the testing instructions that are provided with the test kit and
follow them very carefully.
