Main highlights

The protection you need – no more green pool water. While pool algicide effectively combats algae, it is still particularly important for clear water to always combine it with other agents such as chlorine. These synergies ensure comprehensive disinfection and cleanliness of your pool.
The optimal use: a pH value between 7.0 - 7.4 is essential before using any pool chemistry. In case of existing algae infestation, mix our algae killer ideally in a bucket with water and then add to the pool water along the edge when the filter system is running.
Perfect and easy – don't let it get that far. Not only a reliable aid for already existing algae infestation, but also ideal as a preventive protection. Before filling the pool, simply apply undiluted with a sponge to the pool floor and walls (wear gloves).
Made in Europe: rely on European quality and safety. Our products are produced in Europe to the highest standards and stand for safety and purity. As experts in pool chemistry, we offer you everything you need for perfect pool care and safe bathing pleasure. Registration: BAuA N-113142
Algo-protection form: our pool algae repellent works absolutely quickly and effectively against the infestation of green algae and blue algae thanks to its innovative algo-shield formula. It is foam-free and ensures crystal clear and hygienic water - a must for a pleasant and clean bathing experience.

Undisturbed bathing fun: the pool care product eliminates slippery and thus risk of accidents on the edge of the pool and floor - these pads always form in case of insufficient water care with chlorine
Full effectiveness: the pool cleaner for algae removal is optimally compatible with disinfectants for the treatment of bath water and is therefore the ideal addition to Söll AquaDes
Effective against green water: the Söll Algae Free pool cleaning (2.5 l for 25,000 litres) has a long-lasting effect against single-celled green algae and blue-green algae in small swimming pools, pools and paddling pools
Eco tip: used swimming water does not have to be discharged into the sewer system unused - water treated with algae free can be used to irrigate the crops and garden plants
Easy pool care: thanks to the liquid formula, the foam-free pool agent can be used easily (add 20 ml to 200 litres of bath water) - a prior measurement of the pH value is not necessary
