What are swimming pool chemicals? All swimming pools require two things - sanitization and circulation.
Circulation is accomplished with the pool filter system.
Sanitization happens with the use of chemicals.
There are two main chemicals on the market - bromine and chlorine - both with benefits and drawbacks.
Why are pool chemicals necessary? Bacteria and other contaminants can live in your pool water.
Some of these bacteria when they reach a high enough level can cause infections and illnesses.
Some of the illnesses include meningoencephalitis, legionella and staphylococcus.
Traditional pool chemicals Bromine Bromine is a chlorine-based chemical, but one that is much gentler than chlorine.
It can be a good option for folks who have sensitive skin - but keep in mind that it will not work for those with chlorine allergies.
Bromine also has a gentler scent which may appeal to many who find chlorine too strong a smell.
Bromine dissolves much more slowly than chlorine however, which means an automatic chemical feeder will be necessary - and may be an additional expense.
Chlorine Chlorine is the more traditional pool chemical but is well known for it's drawbacks.
The strong smell and harsh nature of chlorine is not for everyone.
It can be less expensive and easier to use however.
Chlorine traps bacteria, but once trapped the chlorine becomes consumed which is why regular additions of chlorine to the pool water is necessary.
What are the risks? Using chlorine and bromine can cause discoloration of hair and swimsuits.
It can also cause skin and eye irritation.
Chlorine and bromine can also cause a great deal of wear and tear on a pool's circulation system.
Alternatives to pool chemicals Ozone generators inject ozone into the water as it passes through the pump and sanitizes the water in that way.
Mineral sanitization - generally silver or copper, known for their antibacterial properties - can kill bacteria when it passes through an ionization device.
Catalytic sanitation use oxidation and minerals to kill bacteria.
All of these alternatives can be more expensive than the traditional pool chemicals.
The benefits are a reduction in the reliance on chemicals to clean your pool.
Many people find that they prefer the softer smell and gentler action of ozonators or ionizers.
Summary How you keep your swimming pool clean and free of bacteria is a personal choice and will depend on your individual circumstances and preferences.
Pool chemicals and alternative sanitization systems are available from a wide variety of sources.
Once you have decided how you will sanitize your swimming pool remember to read all manufacturers instructions and timeframes.
