pool filter cleaningin media city.

In most countries a pool has an opening day and a closing day. In the UAE it never closes, but it does change character completely four or five times a year. From October to April the water sits between roughly 18 and 26 degrees, chemical demand is modest, and a weekly visit is usually enough. From May onwards the water climbs past 30 degrees, chlorine starts disappearing almost as fast as it goes in, and evaporation can pull several millimetres of water out of the pool every day.

The practical consequence is that the same pool needs different service intensity, different chemicals and sometimes different equipment settings depending on the month. The sections below walk through the year in order, because that is how the problems actually arrive.

The eight or so weeks before June are the most valuable in the pool year. The water is warm enough to work comfortably but not yet hot enough to punish mistakes, and every serious technician in the country knows that whatever is marginal in April will fail in July. This is when the annual equipment audit belongs: pump seals and O-rings checked for perishing, the pressure gauge on the filter verified against a known-clean baseline, timer settings reviewed, and the skimmer weirs and baskets inspected for cracks.

It is also the season for sand filter media changes. Filter sand in the UAE degrades faster than manufacturers' generic three-to-five-year guidance suggests, because the dust load and near-constant filtration grind the grains smooth and channel the bed. If the sand has not been changed in three years, or backwashing no longer brings the pressure back down, book the change now rather than discovering the problem during an August algae fight. Many owners switch to glass media at this point, which resists channelling and typically lasts longer.

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.

Salt chlorination generates chlorine continuously by electrolysis from mildly salty water, around a tenth the salinity of the sea. Swimmers generally find the water softer, and there are no tablets to store in a 45-degree garage. The catch is the cell: hot water and heavy summer duty shorten its life, scale builds quickly given the region's hard fill water, and replacement cells are a four-figure item in dirhams. A salt pool that is not descaled and inspected before summer often limps through August producing half the chlorine it claims to.
