The most popular addition to new and existing pools is a salt system.  People have also called them “saline” systems which is not necessarily correct.  Salt chlorinator, chlorine generator or salt system are more accurate terms. Whatever you want to call it, the addition of a salt system will ease your chemistry headaches as long as you keep a few things in mind;

  1. Salt does not escape your pool from evaporation. If you are having to add water to your pool constantly or if there is a particularly extended rain event that will dilute the concentration of salt and therefore you need to monitor that occasionally to make sure the salt cell has enough salt in the water to produce the chlorine needed.
  2. You need to guard the chlorine you are producing with a sunscreen.  That sunscreen is your stabilizer level.  Like salt, stabilizer (or cyanuric acid) does not evaporate and it has the same dilution characteristics as salt.  So it’s important to check for the stabilizer level when you check the salt level in your pool.

Salt is very inexpensive, especially compared to chlorine.  If you can tolerate the up front cost of the system, we believe it is well worth it.
