Salt Pool or Chlorine Pool: What Is Actually Different

One of the questions we are asked most often is whether a salt system is worth it.

Before answering, one misunderstanding needs clearing up.

A salt pool is not a pool without chlorine

Many people believe a salt system means chlorine-free water. It does not.

What actually happens is that a salt pool sanitises with chlorine too. Instead of you buying chlorine and adding it, a chlorinator splits the salt already dissolved in the water into chlorine automatically, and that chlorine recombines back into salt in a continuous cycle.

So what changes is not whether there is chlorine, but how the chlorine gets into the water — and that does genuinely change the experience of using the pool.

What a salt system is better at

The water feels softer and irritates less. Chlorine is produced continuously in small amounts rather than added in a large dose that then declines, so the level stays far more even. People who get red eyes or dry skin in a traditional pool usually notice the difference.

No harsh chlorine smell. The smell people associate with chlorine is actually chloramine, formed when chlorine reacts with sweat and other contaminants. A properly set up salt pool produces less of it.

No hauling pails and no chemicals stored at home. Families with small children tend to weigh this heavily.

Lower monthly running cost. Pool salt is much cheaper than chlorine and is topped up rarely, because the salt does not disappear — it is only lost through splash-out and backwashing.

What to know before deciding

Higher upfront cost. You have to buy the chlorinator at the start, where a chlorine pool needs almost no equipment.

The cell wears out. The titanium plates that generate the chlorine degrade with use and need replacing eventually. Budget for it as a long-term cost. We stock replacement titanium cells and cell housings.

You still have to manage the water. This one matters. A salt system handles chlorine and nothing else. pH, alkalinity and hardness still need testing and correcting exactly as in any other pool.

In fact salt pools tend to drift upward in pH as a by-product of generating chlorine, so you will be keeping pH Minus on hand regardless.

You also have to test salt. The salt level needs to stay in the range the unit specifies, typically 3,000-4,000 ppm. Test with salt test strips. Too low and the unit cannot generate enough chlorine; too high and it can corrode equipment.

So which should you choose

A chlorine pool suits a limited upfront budget, a pool used seasonally or occasionally, and an owner who does not mind dosing chlorine themselves each week.

A salt system suits a household that swims regularly, families with children or sensitive skin, and anyone happy to spend more at the start to make every week easier afterwards.

For a typical home pool we stock the 2-in-1 X Series chlorinator, sized to your pool. For larger or commercial pools needing higher output and finer control, there is SChlor, which includes a timer for the filter pump and carries a 3-year warranty on the cell plates.

Can an existing chlorine pool be converted

Yes, and without rebuilding anything. Typically the chlorinator is plumbed into the existing pipework after the filter, and salt is added to the pool to reach the level the unit needs.

The thing to check first is whether the existing equipment is rated for salt water, particularly certain metal components.
