10018CSP Spa PH Up Pool Balancer, 18 oz.

Works great for our hot tub

We needed to increase the pH in a hot tub and this was a reasonably priced option, with solid reviews. It arrived in a reasonable amount of time and in good condition. The instructions were clear on how much to add and the measurements utilized the bottle cap as the measurement device which is nice because it meant I did not have to find a scoop/teaspoon etc. After following the instructions, and adding the recommended amount of pH UP, the water now measures in the good range again. If I used all of this container, I would not hesitate to purchase the same brand from the same supplier.

Does the job. Would buy again.

I have Clorox brand for two other chemicals to help balance the water in my hot tub. This is my first time buying Clorox brand for PH control. I will say, that compared to other brands, I do find I have to use almost double the amount to achieve the balance when comparing to different brands. So it may be less expensive per LB, but am using twice as much (and twice as often).

I thought it was liquid .. but its not . its fine crystal power like .. works great for PH up in spa . I just put in spa yesterday so I am waiting to see if I have a good resolve rate .. I do have spa vac if that happens ...

Great for my portable spa.

Works for boosting spa pH. I use it as needed based on test strips. It does what it says. No complaints. And I would purchase this product again.

Good
