Review: Good value, great quality. - I’d say this increaser is higher quality than what I’ve used before, meaning I use less of it but get quicker results. A little goes a long way. I’ve owned hot tubs for over 30 years and have used everything from every major brand. With spa chemicals, you usually get what you pay for. In the last year, I’ve been so impressed with the quality of their products that I started using this brand almost exclusively. 2 thumbs up.
