In 2018 we bought a whirlpool from the company Armstark brand Maxxus (2000 litres). From the beginning, we were never really satisfied with the water quality. When skin itching was added, I searched the internet for chlorine-free alternatives and came across SpaBalancer. Since then, we have been using all SpaBalancer products. Now everything is fine and on top of that we have a TOP water quality.
