Firstly, it is important to emphasize that the chemicals used for water treatment and pool maintenance are substances that can be harmful to health if mishandled or used contrary to instructions. Therefore, we recommend adhering to several basic principles:

  • Always store chemicals in their original packaging in a dry place.
  • Keep chemicals out of the reach of children.
  • Always follow the recommendations provided on the packaging or in the included instructions.
  • Never mix chemicals with other substances unless explicitly directed by the manufacturer, as this can lead to fire, burns, the release of toxic gases, or other unpredictable situations.


The first step is to clean the pool. Remove any debris such as leaves, sand, and trash from the pool basin.

Before filling the pool, it's essential to inspect the pool's structure and equipment. For wooden pools, pay attention to the condition of the boards, checking for cracks, signs of excessive wear, or protruding mounting elements such as screws. Also, inspect the ladders and ensure that the skimmer does not contain unwanted objects. Verify that electrical wires and equipment are adequately protected.

After cleaning the pool, use appropriate cleaning agents to clean the inner walls and bottom,following the included instructions. Before filling with water for swimming, thoroughly rinse the cleaned interior of the pool and remove any contaminated water.

The next step is to fill the pool with water and begin its treatment. The water treatment process consists of several stages and may take several days.

Stage 1 – Adjusting the Water pH Level

The pH level of the water is essential, even though we can't see it. It affects our skin, water quality, and the durability of pool components. The ideal pH range for pools is between pH 7.0 and pH 7.4.

Depending on whether the pH is too high or too low, you can adjust it using special pH Plus or pH Minus products.

Proper pH is crucial because:

  • pH above 7.4 reduces the effectiveness of disinfectant agents, requiring more of them, such as chlorine, to achieve the same bactericidal effect.
  • High pH can promote algae growth, necessitating additional water treatment to eliminate them and restore water clarity.
  • A pH below 7 or above 7.4 can cause skin irritations, redness, and allergic reactions.
  • Low pH can corrode metal parts of the pool, leading to faster wear and an unsightly appearance.
  • in addition to the previously mentioned skin problems a pH above 7.4 can also irritate eyes, reduce disinfection effectiveness, worsen coagulation, and cause calcium precipitation (scaling).

Stage 2 – Algae Prevention

Once the pH level is within the recommended range, you can protect the water from algae growth using special products such as ALGEN anti-algae Agent. Measure the required amount and pour it into the skimmer while the water is circulating. Ensure you follow the instructions closely. The skimmer is a pool water purifier that draws in water and small floating impurities, releasing clean water. This ensures even distribution of the anti-algae product.

Stage 3 – Water Coagulation

Coagulation is the process of removing the finest particles suspended in the water, even those not visible by the unaided eye. This process makes the water crystal clear. Use appropriate liquid, gel, or tablet coagulants following the instructions. After adding the coagulant, start filtration and filter the water until it becomes crystal clear. The coagulant causes micro-contaminants to aggregate into larger "flakes" that settle at the pool bottom. Remove them with an underwater vacuum cleaner.

Stage 4 – Water Disinfection

The final step in water treatment is disinfection. Use fast-dissolving chlorine-based products for this purpose. Place tablets in the skimmer with water circulation, or dissolve granules in a bucket and pour the solution into the skimmer.

Note: Always read the instructions before using such products. Never put tablets or granules directly into the pool, as the pool material (plastic or vinyl) can discolour.

After these procedures, the pool and water are safe and ready for use.


With the initial water treatment complete, leave the filter pump running until the water becomes crystal clear, and the chlorine level drops to 0.5 mg/liter. At this point, the water is ready for swimming.

You will need to maintain the water quality to prevent it from deteriorating due to external influences (rain, dust, and other contaminants brought in by bathers). Proper water filtration and water quality measurement are crucial. Use easy-to-use devices to measure pH and chlorine levels in the water.

Remember that the pH value should be maintained between 7 and 7.4 (ideally 7.0), and the chlorine level should be between 0.3 and 0.6 mg per liter. Lower levels can promote algae and microorganism growth, while exceeding the upper limit can cause skin irritations and allergic reactions.

Slow-dissolving chlorine tablets or multifunctional tablets containing chlorine, algae control, and coagulant are used to maintain the required chlorine concentration. These can be placed in special dispensers or added to the skimmer. Check the chlorine level daily and adjust as needed. If the pool doesn't have a dispenser (floater), use small chlorine tablets placed in the skimmer.

If you use regular chlorine tablets, also add Algae Algae Control and a coagulant in the amounts specified on the labels.

ATTENTION! Note that chlorine compound doses are approximate, so always rely on measurement results.

In addition to water treatment with filtration and chemicals, you must mechanically clean the pool. Underwater vacuum cleaners, special brushes, and nets for catching floating or settled debris are used for this purpose.

Pump and Filter Operation Time:

Typically, running the pump twice a day for 2 to 4 hours, depending on the pool's size, contamination level, and pump capacity, is sufficient. During prolonged periods of hot weather, it's advisable to double the filter and pump operating time.

To achieve long-term water cleanliness, it's recommended to "shock" the water with chlorine every 2 to 3 weeks. This process eliminates microorganisms that may have become resistant to regular chlorine levels. Use a chlorine dose similar to the one used for spring preparation, with chlorine concentration ranging from 2 to 3 mg per litre. Perform the chlorine shock treatment in the evening, and swimming should only be allowed once the chlorine level drops to 0.6 or lower.


To avoid problems when reopening the pool in spring, it's essential to prepare it properly for winter.

In the fall, release water from the pool through the jets, leaving only a small amount. Add a winterizing product to prevent algae growth and prevent dirt from adhering to the walls and mineral deposits from settling. Next, drain water from the skimmer, piping, and filter, and dismantle the pump for winter storage in a frost-free location.

What to do if the water turns green due to algae growth:

  • First, measure the pH value. If it's higher than 7.4, lower it to 7.0 max 7.4.
  • Add ALGEN anti-algae Agent to the water in the same amount as during spring treatment.
  • Add chlorine tablets to the water in the same amount as during spring treatment or use a shock treatment.
  • Continuously filter the water until it becomes crystal clear.

Enjoy your swim! :)
