Chlorine tablets or a salt system: what actually survives a UAE summer
Both sanitising approaches work here, but they fail in different ways and the UAE climate stresses each of them at a specific point. Traditional chlorine dosing — trichlor tablets in a floater or feeder, topped up with liquid chlorine in summer — is cheap and simple, and every technician in the country understands it. Its weakness is the stabiliser problem described earlier: tablets keep adding cyanuric acid, and by September an undiluted pool can be chemically locked, showing chlorine on the test strip that is doing very little in the water.
The honest summary for the UAE: salt suits owners who want stable day-to-day water quality and will fund the cell as a consumable; tablet-and-liquid dosing suits owners who want the lowest running cost and have a reliable service visit schedule. Neither eliminates the need for a technician; both change what the technician should be checking.
