To choose a pool filter on sale, calculate the pool's total volume in cubic meters and divide it by four hours to find the minimum required flow rate. Installing a unit with lower capacity will clog the filter media and quickly make the water cloudy.

To make the right technical purchase, check the following operating factors:

• Pump's nominal flow rate in cubic meters per hour compared with the total liters of water.
• Sand tank diameter, as with the Star 300 sand filter with pump, designed for small volumes or above-ground pools.
• Compatibility with the diameter of the connecting hoses or pipes (usually 32 mm or 38 mm).
• Top- or side-mounted multiport valve with wash, rinse and filtration settings.

Sizing with a margin of 15% above the calculated volume helps prevent overloads on extremely hot days.

A suction-side hydraulic pool cleaner connected to the main drain or skimmer is the most efficient solution for that power without the need to add electrical control panels. With a three-quarter-horsepower motor, the flow rate is more than sufficient to activate the continuous-drive turbines.

The Zodiac MX8 automatic pool cleaner is ideal because it requires a minimum power of 0.75 HP to drive its tracks and clean the floor and walls. By eliminating the need for transformers or separate electric motors, it reduces the risk of electronic failures and minimizes the initial cost.

Check that the pump pre-filter is clean before each cycle to maintain constant vacuum pressure.

All items sold in the promotional section come with exactly the same official statutory warranty required by current regulations for new products. Price reductions are due to temporary promotions, agreements with manufacturers or seasonal stock rotation, never to defects or malfunctions.

Each unit is shipped factory-sealed and includes its corresponding assembly manuals, European Union conformity seals, and technical support for original spare parts. In the event of an operational issue during the statutory warranty period, the customer can arrange assistance directly with the manufacturer's technical service department or through our customer service channels.

Chlorine tablets retain their active concentration for more than two years if stored in their original airtight packaging, protected from moisture and away from direct sunlight. Buying bulk sizes or multipacks significantly reduces the cost per kilogram of active ingredient.

Products such as Quimiclor PS 5 Effects Quimicamp 5 kg – 250 g Tablets (Multi-Action Chlorine) use stabilizing additives against ultraviolet rays that slow the decomposition of trichloroisocyanuric acid. To prevent loss of effectiveness:

• Keep the bucket lid completely closed after each dose.
• Avoid placing the product in damp areas such as underground filtration equipment rooms.
• Do not mix tablets with different chemical compositions in the same dispenser.

When stored under these conditions, chlorine will retain the same disinfecting capacity in subsequent seasons.

The main difference lies in the source of the driving force: the manual pool cleaner requires physical guidance using a telescopic pole, while the automatic model uses the kinetic energy generated by the pump to move autonomously across the pool surface.

Direct technical comparison between the two systems:

• Maintenance time: The manual cleaner requires 30 to 60 minutes of human work per session; the automatic model operates unsupervised during the usual filtration cycle.
• Cleaning pattern: manual cleaners let you target specific corners; hydraulic cleaners follow a random path powered by diaphragms or mechanical turbines.
• Cost: manual options require a lower initial investment, while automatic ones pay for themselves by reducing operator fatigue.

Choosing a discounted automatic cleaner saves hours of weekly maintenance while keeping the water circulating.

Installing an overpowered pump creates excessive water flow through the filter bed, preventing the sand from trapping suspended particles and sending the dirt straight back into the pool.

The filtration rate must not exceed 50 cubic meters per hour per square meter of filter surface area. If you pair a 1 HP pump (with a flow rate of around 14 or 16 m³/h) with a small filter measuring 300 or 400 mm in diameter, you will cause:

• Excessive pressure in the filter tank, with a risk of deformation or structural leaks at the seals.
• Breakage or collapse of the lower filter laterals due to excessive hydraulic load.
• Channeling in the silica sand bed, preventing water clarification.

Always consult the flow rate-to-diameter compatibility tables before opting for a discounted, higher-powered motor.

To verify whether an accessory is compatible, check the manufacturer's original reference code, the connection thread diameter, and the rated operating voltage.

For mechanical components such as selector valves, check whether the connection port is 1½ inches or 2 inches, and whether the tank is secured with a metal clamp or a direct-thread connection. For liners for above-ground pools, check the outer diameter and the height of the sheet-metal wall to the millimeter (for example, 120 cm or 132 cm).
