For over 15 years I have tried the quality of my pool water to make as much as possible. This is my most well managed, but it was always a very costly affair. This year, now I bought this product for the first time and I have to say that the consumption of additional water care products since plummeting war.Nicht only that the price / performance ratio is absolutely correct in this product, the water quality was without addition of other agents throughout the summer excellent and there is even a part in stock for the next year! The processing and delivery of the order was exemplary! -thanks-
