We have been using SpaBalancer Basic and Ultrashock for five months now and are very satisfied with them. For one and a half years we have owned a whirlpool from Fonteyn Spa, model Typhoon Waver. For a year we tried different products, but the water never stayed clear and we had to change the water in the spa every two months. Now we have finally discovered your super SpaBalancer and Ultrashock: no more chlorine smell and clear water for five months. This is what we were looking for!
