4-in-1 Pool Chemical Set The set provides comprehensive care for pool water, from disinfection to pH stabilization to preventing algae growth.
POOL CHEMISTRY 4-in-1 Pool Set chlorine algae is a complete pool water care set that combines rapid chlorination, continuous disinfection, pH adjustment, and algae protection. It is a practical solution for those who want to keep pool water in good condition throughout the season and ensure its clarity, microbiological cleanliness, and comfortable use. The set includes four complementary products: shock chlorine, 20 g chlorine tablets, pH Minus, and Algen Super.

The 4-in-1 pool chemistry set has been composed to cover the most important areas of pool water treatment: disinfection, parameter stabilization, and algae prevention. The individual products can be used according to the needs of the pool and the current condition of the water.
The set includes:
This is a stabilized organic chlorinating granulate containing around 56% active chlorine. The product has neutral pH, dissolves quickly and completely, and is suitable even for hard pool water. It is ideal wherever rapid chlorination and a quick response to deteriorating water quality are needed.
Action: biocidal against Pseudomonas aeruginosa and Staphylococcus aureus (10 mg/l, 60 min, 20°C).
Slow-dissolving 20 g tablets contain around 90% active chlorine, as well as a coagulant, pH stabilizer, and algae control agent. This product is intended for regular use and helps maintain the microbiological cleanliness of pool water.
Action: pool water disinfection, biocidal action against bacteria, fungi, yeast-like organisms, and algae. Thanks to their slow dissolution, the tablets are suitable for continuous use to maintain proper water quality.
An acidic granulate designed to lower the pH of pool water from an alkaline range to the ideal level of 7.0–7.4. The product contains no chlorides, is suitable for manual dosing, and is characterized by a long shelf life.
Action: lowering the pH value in pool water.
An anti-algae agent intended to prevent algae growth in pools. The product contains no chlorine, acts for a long time, has a neutral pH, is safe for the skin, does not cause foaming, and supports water clarity.
Action: bactericidal, fungicidal against Candida albicans, and algicidal. Due to the absence of chlorine and heavy metals, it is suitable for all types of pools.
The products included in the set complement one another. Shock chlorine is used when rapid disinfection is needed. The multi-functional tablets are responsible for continuously maintaining water quality. pH Minus helps bring the reaction into the 7.0–7.4 range, which is important for the effectiveness of the other products. Algen Super limits algae growth and supports maintaining clear water.
Important: biocidal products must be used with precautions. Read the label and product information before each use.

The set includes four products: Chlor-Shock Granules 1 kg, Multi-functional Tablets 20 g 1 kg, pH Minus Granules 1.5 kg, and Algen Super 1 kg. Each one is responsible for a different stage of pool water care.
Shock chlorine is intended for rapid chlorination when intensive water disinfection is needed. The product dissolves quickly and completely and is suitable even for hard pool water.
The tablets are used for continuous pool water disinfection. They are slow-dissolving and contain around 90% active chlorine, as well as a coagulant, pH stabilizer, and algae control agent.
pH Minus helps lower excessively high water pH to the ideal range of 7.0–7.4. Maintaining the correct pH supports the effectiveness of the other pool care products.
No. Algen Super is a chlorine-free product with neutral pH, intended to prevent algae growth. It acts long-term, does not cause foaming, and can be used in various types of pools.
Yes, the Algen Super included in the set is suitable for all types of pools, and the entire kit has been prepared with comprehensive pool water care in typical private and seasonal applications in mind.
Chlor-Shock has biocidal action against Pseudomonas aeruginosa and Staphylococcus aureus at parameters of 10 mg/l, 60 minutes, and 20°C. The multi-functional tablets act against bacteria, fungi, yeast-like organisms, and algae, while Algen Super has bactericidal, fungicidal action against Candida albicans, and algicidal action.
Yes. These are biocidal products, so they should be used carefully and in accordance with the label and product information. Pay attention to the hazard statements, including H272, H302, H319, H335, and H410.
