Salt vs. Chlorine Pools

The salt vs. chlorine debate is one that has been argued for a long time, with advocates from both sides listing benefits of either. When considering whether you would like a salt water pool or one that makes use of chlorine, the most important things to consider include health, safety, cost and maintenance. Keep in mind that one is not necessarily better than the other, though some may suit your needs better than others.


Salt water pools:

Salt water chlorination cleans and sanitises pools by making use of dissolved salts, using electrolysis to break down the salt and then adds it to the water. Initially, making your pool a salt water one may be expensive, but this cost is balanced out since the salt never actually disappears from the water, and periodical salt additions are much cheaper. PH levels must also be maintained on a regular basis by the pool owner when using salt, and the salt-to-water ratio maintained.

Advantages of salt water pools include:

  • Less maintenance and lower overall costs
  • Eliminates eye irritation and soreness, as well as dry skin
  • Safer for pets
  • Less harmful on hair and swimming costumes – no bleach
  • Has an oceanic effect
  • No chlorine tastes and smells
  • Will not be evaporated
  • Assists in sun-tanning

Chlorinated pools:

Chlorine is the most commonly used method of pool cleaning systems. It works by pool owners adding chlorine tablets either to a pump unit or in a floating device that dilutes the chlorine tablets over a period of time in the water. Chlorine is considered slightly more harmful than other alternatives because the element of chlorine itself is highly toxic. It is, however, important to keep in mind that the chlorine used in swimming pool cleaning is a compound formulated specifically for pools.

Advantages of chlorine include:

  • Stronger in terms of bacterial clean-up
  • Clears water faster
  • Easy to operate (adding tablets to the system)
  • Costs to implement chlorine system are low
  • Readily available
  • Kills mildew, mould and bacteria living in water

There are advantages of both types of pools. It all comes down to your personal choice.
