Main highlights

Undisturbed bathing fun: the pool agent eliminates slippery and thus risk of accident deposits on the edge of the pool and floor - these pads always form with insufficient water care with chlorine
Full effectiveness: the pool care product 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 AlgaeFrei pool cleaning (1 litre for 10,000 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 cleaner can be used easily (add 20 ml to 200 litres of bath water) - a prior measurement of the pH value is not necessary
