Saltwater is the most common way Australian pools are sanitised, and for good reason: it keeps the water clean and feels gentler than a pool dosed with liquid chlorine. The system itself is straightforward. A modest amount of pool salt is dissolved in the water, and a salt-chlorinator cell passes a low electrical current through it to split the salt and generate chlorine on site, continuously, as the water circulates. That chlorine sanitises the pool exactly as bought chlorine would, then reverts to salt, so the Saltwater Pool Systems largely recycles its own sanitiser rather than consuming drums of chemical. For a St Marys East household the practical benefits are real: no storing or handling of harsh liquid chlorine, more stable chlorine levels through the day, and water that most people find softer and less irritating to skin and eyes. The salt concentration is low, well below seawater, so the water does not taste especially salty. Upkeep is simpler but not nil; salt is topped up occasionally, the chlorinator cell is cleaned of scale from time to time, and pH still needs checking, since chlorine generation nudges it upward. We install the Saltwater Pool Systems on new Penrith pools and retrofit it to existing ones, sizing the chlorinator to the pool's volume so it can keep up through the warm Sydney - Outer West and Blue Mountains months when demand peaks. We position the cell and control box for easy servicing and set the run time to suit the pool. The result is a St Marys East pool that is clean, comfortable to swim in, and cheaper and easier to look after than the old chlorine-by-hand routine.
