We have found that while there are plenty of choices available to the swimming pool consumer today, nothing is more tried and true than the liquid chlorine system. Many marketing firms, in order to “create a need” for their products, have tried to sell their customers on the notion that chlorine is bad, and have chosen, of course, to speak only about its qualities when used improperly. This letter is an attempt to challenge those ideas and remind you of a little history.
Chlorine is an
element. It exists naturally in the
environment, and is a part of our everyday lives. It would be impossible to remove its existence and enjoy the
healthy lifestyles we take for granted everyday. Chlorine is still found in your city water, is in most of the
cleaning products available on the market, is used to sanitize just about
everything everywhere – is even on your dinner table in the form of a salt - so
why would you not want to use it in your pool?
Here are some
myths about chlorine that need dispelled:
This is simply not true. Any chemical in excess will have a negative
effect on something. Chlorine used
responsibly will yield absolutely crystal clear water, with no concerns of
anything “un-natural” in the water. If
you choose to use a granular form of chlorine, and throw it in the pool – a
very irresponsible way to use such a product – then yes, you run the risk of
damaging your liner by bleaching. But
why would you want to do such a thing with any chemical? Almost all chemicals need diluted in water
before adding to the pool.
Also a great mystery about the
properties of chlorine. Liquid chlorine
(12.5% bleach) has almost no pungent odor, so why when keeping levels of
chlorine in the parts per million range (that is, one part chlorine to one
million parts water), do we sometimes smell chlorine? The answer is simple.
Liquid chlorine in your pool will mix with ammonia from swimmers bodies
(always present from sweat/urine, etc.) and produce a gas that can be quite
pungent. When a pool receives heavy
use, and has a good level of chlorine present, this can occur in amounts that
are bothersome. The resolution is
simply to shock with more chlorine (which “oxidizes” the ammonia out of the
water), or use a non-chlorine shock treatment (a “monopersulfate” chemical)
which also accomplishes the same end result without raising the chlorine levels
as high as is needed when shocking.
Many people feel compelled to
say that there is “too much chlorine” in the pool when they smell this
odor. In fact, considering that the
“fix” is to add more chlorine to shock the ammonia out of the water, it can truthfully
be said that there is not enough chlorine in the water. Chlorine combined with ammonia can create
these odors even when very small amounts of chlorine are present.
Unless you are part of a very
small minority of people who are hyper-sensitive to chlorine, the burning of
your eyes will be due to pH levels being incorrect. The pH of the human eye is around 7.3. The further we stray from that pH in a pool, the more burning
sensation you will feel when your eyes are open underwater.
This is only because many
chlorine retailers have done a poor job of marketing the equipment available to
make chlorine use actually MUCH EASIER than using biguanide systems, or other
so-called “alternatives”. A simple
setup with a chlorine pump, complete with built-in timer, can virtually
eliminate the need to remember to add chlorine, or touch the material at
all. We have many customers with this
setup that will attest it is the easiest form of pool water care they have ever
had. The cost of the equipment, plus a
years worth of liquid chlorine and muriatic acid will still chime in less
expensive than treating with Baquacil or Soft Swim or any of the other biguanide
systems which claim to be so maintenance-free.
We do not wish to bad-mouth
these other products, as they have their place in the market. Our goal is to educate the consumer about
the advantages of using a liquid chlorine system.
There are other forms of
chlorine available, such as tablets, sticks, and other shapes of dry
chlorine. These products contain a
chemical called a “stabilizer”, which sounds like something you would want in
your pool. In fact, it can be a
good product in proper use. Its
chemical trade name is Cyanuric Acid; and is used in swimming pools to
retard the suns’ UV rays from depleting chlorine quickly. While in theory this seems like a good
thing, you must understand that at the same time, stabilizer inhibits the
ability of chlorine to kill unwanted organisms in the pool, such as viruses,
bacteria and algae. The more stabilizer
you add to the pool, the longer the chlorine stays in the pool. Likewise, the more stabilizer you add to the
pool, the less effective chlorine is in killing the “bad guys”. In essence, the chlorine lasts longer, but
does less.
Why do we recommend liquid
chlorine over tablets? Because each
tablet contains this stabilizer, and each time you add a new tablet, you
are increasing the level of stabilizer in your pool. This stabilizer level NEVER goes down unless you drain and
refill the pool. There is no chemical
in the world that can reverse or lower its presence in the pool. That is why so many tablet users have “sworn
off chlorine” – because they use it successfully for the first few years – and
– unknowingly – build up such a high level of stabilizer that the chlorine no
longer works properly, if at all. No
retailer who sells tablets and does not recommend liquid chlorine will explain
this to you. This is true for one
simple reason – there is a much higher mark-up on chlorine tablets than there
is in liquid chlorine. In order to sell
liquid chlorine profitably, a retailer must commit to buying very large
quantities, which requires vast amounts of storage. We purchase liquid chlorine in the thousands of gallons per week,
therefore, we have no motivation to sell a product that we know will only lead
to problems down the road. Other
retailers would like to keep this a secret.
I know this because I have converted literally hundreds of customers to
liquid chlorine for this very reason.
If one would really like to use a stabilizer, it can be added separately
from the chlorine as a stand-alone product, and added at safe levels. Only then, using liquid chlorine, is there
no concern of “over-stabilizing” the water.
You will see many other
chemicals on our shelves and floor in the store. Each one has a legitimate place in the treatment of pool water –
but no product other than liquid chlorine, and occasional treatment of Muriatic
Acid to lower pH levels should ever really be needed. Many of these products are used to treat well water (iron and
copper), cloudy water (from improper filtration), and so on. Many retailers will make sure you walk out
of the store with at least 3-4 of these bottles, whether you need them or
not. I personally have worked for 2
such retailers before starting PA Pool Service, so I speak from
experience. We believe in a very simple
system, and with so many commercial accounts using this system without any problems,
there is no reason why you cannot do the same, and save yourself hundreds, if
not thousands of dollars each year in pool chemicals and treatment.
Most importantly to us - many
customers have found that with the money they save from switching to our
system, they have extra funds to devote to other services we provide – like
weekly monitoring and cleaning of your pool, backwashing your filter, cleaning
your pump and skimmer baskets, and making sure your water chemistry is always
where it is supposed to be.
So what sounds easier to
you? Adding very expensive, strange
chemicals once a week (that have never been approved for commercial use) and
hoping that your pool stays clear – or using an “old fashioned” method that is
tried-and-true, and spending your money on a service that is not
low-maintenance, but virtually no maintenance?
We hope you will choose the
latter. We promise you will not be
disappointed.
Sincerely,
