Cleaning and maintenance of above-ground pools

Cleaning and maintaining above-ground pools requires avoiding direct contact between pure chlorine compounds and the vinyl liner to prevent chemical burns. When applying disinfectants, always use a controlled-dilution device such as the Starpool 18 cm floating chlorine dispenser, ensuring that the chlorine tablets dissolve gradually at the surface.

For mechanical dirt, use a manual pool cleaner with soft polymer or nylon bristles. Never use metal brushes or rigid scrapers, as the thin PVC lining of a tubular or steel-wall pool cannot withstand continuous mechanical abrasion.

To clear cloudy water in a 15 m³ above-ground pool, you need a unit with a minimum flow rate of 4 to 5 m³/h to circulate the water in under four hours. Basic cartridge filters supplied with the pool often become clogged by algae blooms or heavy environmental dust.

Installing the compact Star 300 sand filter with pump provides the power needed to filter microscopic particles and backwash the filter periodically using its built-in multiport valve, ensuring continuous, efficient recirculation.

The main difference lies in the power source and the minimum flow rate required from the filtration system. While a manual vacuum head connects to a pole and uses simple low-pressure suction, a hydraulic automatic pool cleaner requires the pump to deliver a steady flow rate.

• Manual pool cleaners let you target fine dirt buildup without causing smaller pumps to lose their prime.
• Automatic cleaners move across the bottom on their own, using the water flow from the filtration system.
• Automatic cleaners require pumps delivering at least 0.5 HP to move efficiently in taller models.

The strong smell of chlorine combined with the presence of algae indicates an excessive buildup of chloramines and a possible blockage caused by too much stabilizer. To check the water balance with analytical precision, test the reagents with the Lovibond MD200 3-in-1 Photometer for chlorine, pH and cyanuric acid.

Keep the values within these verified operating ranges:

• Water pH: between 7.2 and 7.6 so the disinfectant retains its ability to destroy microorganisms.
• Free residual chlorine: 1.0 to 2.0 ppm in the pool.
• Cyanuric acid: below 50 ppm to prevent water saturation and loss of bactericidal effectiveness.

When cleaning and maintaining above-ground pools, the water should be completely recirculated two to three times a day during the summer months. The exact technical calculation is to divide the pool’s total cubic meters by the pump’s nominal flow rate in m³/h.

For example, a 10 m³ tubular pool equipped with a 2.5 m³/h pump requires at least 4 hours per cycle, with a total daily filtration time of 8 hours spread across the periods of strongest sunlight. If the water temperature exceeds 28 °C, extend operation by an additional two hours to prevent the rapid growth of bacteria and algae.

Winterizing a full above-ground pool requires applying a concentrated winterizing product and keeping the water covered to block algae photosynthesis. Before dosing the product, thoroughly clean the plastic walls and bottom, removing organic sediment with a manual pool vacuum.

Treat the water volume with an initial shock dose of disinfectant, then pour a specific product such as Ivernet pool winterizing treatment, 1 kg container directly around the perimeter with the filtration running. Place an opaque protective cover over the pool to keep out leaves and acid rain, keeping the water clean until reopening in spring 2026.

Yes, it is possible to use multi-action tablets, provided they are never placed directly in the surface skimmer or dropped to the bottom of the pool. The concentrated formulations contain copper sulfate and flocculants which, when left to rest on the vinyl liner, cause permanent stains and degrade the PVC plasticizer.

Dose the tablets only in adjustable floating dispensers or in-line dosing systems connected to the return circuit. This allows the chemical mass to dissolve evenly in the moving flow, ensuring continuous disinfection without compromising the mechanical strength of the liner’s heat-welded seams.
