Cheers Spabalancer! In 2017, at the start of our retirement, we bought an SPA 337-T3 outdoor whirlpool. From the very beginning, we followed the recommendation of our dealer Viva-Aqua and used the water care products from Spabalancer.
Even if it seems a bit more expensive - it's worth it. Easy to use and the result is always perfect water quality. We have only had good experiences and can recommend Spabalancer with a clear conscience.
