How many hours per day should the filtration pump run?
As a general rule, the pump should filter 1 hour for every 10 °C of water temperature. In summer, with water at 28–30 °C, it is usual to filter between 8 and 10 hours per day. In spring and autumn, with water at 15–20 °C, 4–6 hours may be sufficient.
If the pool receives a lot of use or there is a lot of heat, increase the filtration time. Filter preferably during off-peak electricity hours (night or early morning) to reduce the cost of the bill.
What is the ideal pH level for a pool?
The ideal pH range for a pool is between 7.2 and 7.6. Below 7.2, the water is too acidic, irritating the eyes and corroding the metallic elements of the equipment. Above 7.6, chlorine loses its disinfectant effectiveness and scale buildup is favored on walls and filter.
Measure the pH always before adding any chemical product, since pH directly affects the effectiveness of chlorine.
How often should I test the pool water?
It is recommended to test pH and free chlorine at least twice a week during peak season (June-August), and once a week in spring and autumn. On days of heavy use, after heavy rains or after adding new water, it is advisable to do an extra test.
A digital photometer provides more accurate and consistent readings than test strips, making it a better investment for regular monitoring.
What is the best way to clean a pool?
Regular cleaning involves using a pool brush to remove algae and debris from the walls and floor. It is important to clean the pool at least once a week, especially in areas with high sunlight exposure.
Example: If you have a green algae problem, use a pool brush with a long handle to reach all corners and scrub the affected areas thoroughly before shocking the pool.
How do I remove stains from a pool?
Stains can be caused by metals, algae, or other substances. To remove them, use a pool stain remover or a specialized product, which are designed to break down stubborn stains.
Apply the product directly to the stained area and let it sit for the recommended time before scrubbing and rinsing. For best results, use a pool brush to work the product into the surface.
