- pH Up Alkalinity Increaser Spa Water Balancer 2 lb

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.

I used this for pH control in the Hot Tub and it works Great.

My husband and I are new hot tub owners and buying this product made it really easy to care for our tub. The directions are easy to follow and the product works almost instantly. The product arrive in a timely fashion too. I recommend this to anyone who cares for a hot tub!

This product has worked well for me. It raises the ph when used. I’ve purchased it about 3 times now.

I do not hesitate to use this product.

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!

Product worked perfectly fine for my application.

The product itself is fine, but when it arrived, it had spilled into the bag and I lost a bit of the powder.
