Works & last a LONG time
We have used a full line of Hot Tub Things product for 3 years. They are simply to use, keep our large spa clean, clear, and balanced. The ph+ product is used very occasionally and one 32 oz has lasted 3 YEARS!

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.

It’s Baking Soda
Works great but it’s just baking soda. 100% sodium bicarbonate. Does the job but is a pricey at just over $1 per ounce. You can buy this for under .20 cents from grocery store
