In June 2020 I bought a whirlpool from Royal Spa, model Martinique Ultimate, for my garden. The salesman recommended SpaBalancer products to me.
Now I'm glad I took his advice and bought the products. The water care is easy to dose and you get crystal clear water. Even now, after 10 months without refilling, the water in the whirlpool is still clear. I can only recommend the water care products to all whirlpool fans.
Thank you SpaBalancer, keep up the good work :-)
