How Often Should You Clean Your Pool in Los Angeles County?
· 6 min read
Long swim seasons, Santa Ana dust and year-round sun change how often a pool actually needs service. Here's a realistic schedule.
The short answer: weekly, nearly year-round
In Los Angeles County, strong UV burns off chlorine fast from spring through fall and swim season runs long. A weekly service cycle — skim, brush, test, dose, inspect — is the baseline that keeps water stable. Bi-weekly service can work in December through February when demand is lower, but stretching intervals in August almost always ends with cloudy water.
What changes month to month
Spring brings pollen, jacaranda blossom and heavy organic load, which eats sanitizer and clouds water even when your test kit looks fine. Midsummer brings extreme heat, swimmer load and evaporation. Fall brings Santa Ana winds, ash and dust plus leaf drop, which is the single fastest way to stain a plaster surface and clog a skimmer. Each of those needs a different emphasis, not just more chlorine.
The tasks that actually matter
Brushing walls and steps prevents algae from establishing a foothold in the places circulation never reaches. Emptying baskets protects the pump. Testing more than chlorine — alkalinity, cyanuric acid and calcium hardness — is what keeps chemistry from swinging wildly. Filter pressure checks catch flow problems weeks before the water looks bad.
When to bring in a pro
If you are testing twice a week and still fighting cloudiness, or your chlorine demand keeps climbing, the problem is usually circulation or stabilizer levels rather than dosing. That is worth a professional water analysis before you spend more money on chemicals.
