Salt Water Swimming Pools

 Just think about being on the beach, walking along the sand…then looking up at all the houses that are being pounded by the salt water. Think about winter storms and the importance of cleaning your car after the salt adheres to the finish.  While most people want Salt Systems AKA Chlorine generators attached to their pool, they do not realize the future damage being done to the surface and the underlining of the pool, which is caused by the 100’s of pounds of salt being added to the water. Most Above Ground pools actually void the warranty if the home owner attaches a chlorine generator.

     If you are thinking about salt, ask yourself why? Do you think it is non chlorine? Because it’s not. Do you think it is better for the environment? It’s not, some states actually prohibit pool owners from draining their salt pools because they are afraid of salt getting into the streams, rivers, and creeks. Do you think it’s maintenance free? Because it’s not. Do you like the way the water “feels”? There are other products that can give you that same feel, without spending thousands of dollars on a salt system. A chlorine level still needs to be maintained and typically a higher one than just straight Chlorine. Battling PH is also another issue salt customers run into due to the High PH of the liquid Chlorine the generator is making. Concrete/ Gunite customers, not only will you be fighting a high PH with a concrete pool, but now you will also be fighting PH fluctuations due to the Chlorine you are generating. You also need to stay away from Calcium Hypo shocks which can cause scaling on the generator. Scaling can also be caused by high PH levels and phosphates! Even fiberglass pools can be affected by Salt pools, scaling can end up covering the fiberglass shell if proper levels are not maintained. The cells need to be cleaned and a monthly maintenance product should be used as well to help prevent any scaling. The pool will still need to be shocked with either a liquid chlorine or a non chlorine shock when organics start building up in the water. Just be sure you are aware of all the options as well as the pro’s and con’s before making a decision. 

     There are so many different options for chemically maintaining a pool that do not involve the maintenance and corrosiveness of salt/chlorine generators. 

  1. UV/Ozone systems, you treat your drinking water with UV/Ozone, why not your pool water?
  2. Pristine Blue, which is a liquid copper based product added every other week and a non chlorine shock is also used weekly.
  3. The Frog Mineral system, which allows you to use less Chlorine than public drinking water to sanitize the water along with a non Chlorine shock.
  4. Baquacil, which is a soap based sanitizer and a Hydrogen Peroxide shock. 
  5. Bromine, which is slightly less harsh than straight Chlorine.
  6. Good old fashioned Chlorine tablets! 

     Regardless of what you choose to sanitize your water, it is always important to also oxidize/shock your pool every 7-10 days, after heavy bather loads, and heavy rainfall. Outside contaminants get into the water and will eventually build up over time causing some people to wish they never owned a pool. Even if the water is clear, SHOCK. A non chlorine shock can be used, this will still oxidize the water without raising your chlorine level. 

   Below are a few examples of the damage Salt can cause to a pool surface.
