A pool whose chlorinator runs on magnesium-rich minerals instead of plain pool salt. It still makes chlorine. What changes is how the water feels and how low the chlorine can sit. Here is what it is, what it needs, and what it costs in South Africa.
Every salt pool works by electrolysis: water carrying dissolved chloride passes through a cell, and the cell converts it into sanitiser. A magnesium pool is the same machine doing the same job, with magnesium chloride and potassium chloride in the water alongside the sodium instead of sodium alone.
That is the entire difference, and it is enough to change how the water feels. The minerals used are typically Dead Sea derived, which is where the magnesium comes from. How that Dead Sea connection began.
The phrase came out of Australia, where the category is mature and “magnesium pool” is how it is sold. In South Africa the same product is marketed as Mineral Swim by Maytronics. If you have been reading Australian pages and wondering what the local equivalent is called, that is your answer — and the equipment is the same equipment.
| You may have read | What it is here | |
|---|---|---|
| The category | Magnesium pool, magnesium mineral pool | Mineral pool, Mineral Swim |
| The minerals | Dead Sea magnesium | The same Dead Sea minerals, imported |
| The chlorinator | Magnesium-compatible cell | Maytronics EcoSwim or Mineral Swim V2 Pro |
| The upgrade | Ozone or UV as an add-on | Mineral Swim V2 Purifier, into the spare slot |

A magnesium pool is not a different kind of pool. It is a different sanitiser on the pool you have.
Maytronics EcoSwim, six models from 30 000 L to 140 000 L, from R14 899,99. Or a Mineral Swim V2 Pro, which is the same chlorinator with the ozone purifier already fitted.

About the mineralsPump, filter, weir, cleaner, heating, cover. A conversion changes what sanitises the water, not what moves or filters it. The pool is not drained and nothing structural is touched.
A chlorinator that runs on minerals, and the minerals. Both from our own shelf.



Plenty of pages on this subject make claims we are not going to repeat. Here is where the line sits.
The cell makes chlorine. It holds it lower — 0,5–1,0 ppm against a conventional 2,0–3,0 — and with ozone running, Maytronics rate the demand as falling by up to 80%. Lower is not none.
We will tell you the water feels softer, because it does and you can feel it yourself in ten minutes. We will not tell you it treats, soothes or improves any condition. Nobody selling pool equipment is in a position to make that claim.
You still test, balance, brush and backwash. What stops is the twice-weekly job of dosing chlorine by hand. That is a real gain and it is enough of one without embroidering it.
A pool sanitised by an electrolytic cell running on magnesium-rich minerals rather than plain sodium chloride. The cell still makes chlorine; it makes it from magnesium and potassium chloride alongside sodium, which is what gives the water its softer feel.
In practice, yes. “Magnesium pool” and “mineral pool” describe the same thing and are used interchangeably. Maytronics market the category as Mineral Swim in South Africa; the Australian market tends to say magnesium pool.
Yes. Maytronics EcoSwim and Mineral Swim units are sold and supported in South Africa and the Dead Sea minerals are imported. You do not need to build a new pool for one; existing pools convert.
No, and it matters. Epsom salt is magnesium sulphate. Pool minerals are magnesium chloride alongside potassium and sodium chloride — chloride is what the cell needs to make sanitiser. Do not put Epsom salt in a pool expecting it to work.
It makes its own, from the minerals in the water. It is not a chlorine-free pool. Maytronics’ own figures put a Mineral Swim pool at 0,5–1,0 ppm free chlorine against 2,0–3,0 ppm in a conventional one.
Softer. Magnesium-rich water has a different feel on the skin to plain sodium chloride, and most people notice it inside ten minutes. That is what you are buying — we are not going to tell you it does anything for your health.
A chlorinator rated to run on minerals, and the minerals. A Maytronics EcoSwim from R14 899,99 covers pools to 30 000 L; the Mineral Swim V2 Pro range adds the ozone purifier in the same box. Your existing pump, filter and cleaner carry on unchanged.
Mineral Swim Dead Sea Minerals 10 kg is R769,99, and Maytronics put normal use at four to five bags a year on a typical domestic pool. That is more than pool salt. The minerals are what the category is, so it is the honest cost of it.
