Everything you need to know about pool filtration equipment

Having crystal clear water is not a matter of luck, but of having a good filtration system. Pool filters are at the heart of daily maintenance: they remove impurities, improve the effectiveness of chemical treatments and keep the water safe for swimming.
In this guide we explain everything you need to know about the different types of filters, how to install them, use them and keep them in perfect condition.

Types of filters

There are different types of pool filters. Choosing the right one depends on the size of your pool, the usage and the maintenance you are willing to do:

• Cartidge filter: Easy to install and maintain. Ideal for small to medium sized pools.
• Sand filter: More efficient for larger pools, although it requires more space and maintenance (periodic backwashing). Here you can find out in detail how sand scrubbers work.
• Aqualoon filter: More environmentally friendly alternative. Filter balls require less frequent backwashing, which prolongs their life and reduces water consumption.

Where to install the filtration equipment?

• Install the filter on a level and firm surface, close to the pool, but protected from the weather (rain, direct sun, etc.).
• Be sure to leave enough space around it to allow easy access to the equipment for maintenance or cleaning.

Installing the pump and hoses

• Connect the pump to the filter and the hoses to the pool inlet and outlet valves.
• Check that all connections are tight to avoid leaks.
• Use hose clamps to ensure a tight seal.

Electrical

• If the filter is electrically powered, connect it to a splash-proof (GFCI type) outlet.
• If using an extension cord, make sure it is waterproof and suitable for outdoor use.

Initial preparation

• Fill the pool with clean water before turning on the filtration system.
• Remove any large debris (such as leaves or insects) with a net beforehand to avoid clogging the filter.

Use and maintenance tips

• Daily filtration: Turn the pump on at least 8 hours a day (may vary depending on pool size) to keep the water clean.
• Filter cleaning:
• Cartridge: Clean once a week and replace every 1-2 months, depending on usage.
• Sand: Backwash every 1-2 weeks or when the pressure gauge indicates an increase in pressure.
• Aqualoon: Wash and reuse filter media when you notice a decrease in performance.
• Chemical treatment:
• Maintain proper chlorine (1-3 ppm) and pH (7.2-7.6) levels.
• Add a clarifier or algaecide if water is cloudy or algae is present.
• Check connections:
• Regularly inspect hoses and joints for leaks or damage. Replace them if necessary.
• Winter maintenance:
• If the pool will not be used during the cold months, empty the filtration system and store it in a dry place protected from frost.
