Illustration: How often should you maintain your pool?

Maintaining a pool isn't about doing everything, all the time. It's about doing the right things at the right moment. Here, week by week and season by season, is the real rhythm that works in the Var — no wasted products, no ruined weekends.

The weekly rhythm (May → September)

Every week, ideally on the same day, you:

  • Measure pH and chlorine (test strips or an electronic tester).
  • Empty the baskets in the skimmers and the pump pre-filter.
  • Brush the waterline if it's staining.
  • Check the filter pressure.

Fifteen minutes is enough. The secret is regularity: one missed week often doubles the amount of product needed to catch up.

The monthly rhythm

Once a month:

  • Backwash the sand filter (or clean the cartridge).
  • Full test: pH, chlorine, alkalinity, stabiliser.
  • Light shock treatment if the water starts to look off.
  • Inspect the plant room: leaks, unusual noises, limescale.

If a point feels unclear, a 30-minute water quality check sets everything straight.

The seasonal rhythm

Four visits structure the year in the Var:

  • March: spring start-up.
  • June: deep filter clean, equipment check.
  • September: pool clean before the end of the season.
  • November: winterising.

Do these four visits properly and your weekly maintenance stays very light.

DIY or delegate?

The simple rule: if maintenance becomes a source of stress, delegate it. Many of our clients keep the weekly tasks (skimmers, test strips) and leave the monthly and seasonal visits to Pool-Hero. It's the best balance of peace of mind and budget.

A one-off maintenance visit costs between €70 and €120. An annual plan is often cheaper than an emergency clean-up after green water.

The most common mistakes

  • Over-dosing chlorine out of fear it isn't enough.
  • Forgetting the stabiliser: your chlorine burns off in the sun within hours.
  • Never cleaning the filter because "the pressure looks normal".
  • Stopping filtration overnight in high summer to save money: that's exactly when algae start growing.

Frequently asked questions

How long should filtration run in summer?+

Simple rule: filtration time = water temperature / 2. At 26 °C, that's about 13 hours a day. It's best to filter during the day, when temperature and UV exposure are at their peak.

When does the filter really need cleaning?+

When the pressure rises 0.3 to 0.5 bar above the normal reading. Generally once a month in peak season.

Do you need to maintain a pool in winter in the Var?+

Yes, with active winterising: filtration runs a few hours a day during cold spells, and a monthly visual check is enough. That's the advantage of the Mediterranean climate.

How much does regular maintenance cost?+

A one-off maintenance visit with Pool-Hero starts at €70. A regular maintenance plan in the Var starts around €80/month and includes visits, water checks and alerts.
