Clorox Pool&Spa pH Up, Raises pH in Spa Water, Safe for All Types, 18 Ounce (Pack of 1)

works good don't smell cost was fair

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.

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.

Works very Good!

Works as expected,

Clorox Soap Cleaner is highly effective at cutting through grime and leaving surfaces sparkling clean with a fresh, pleasant scent.

I use the Clorox Spa 10018CSP pH Up to raise the level of PH in my hot tub when it is low. It is a must have for hot tub maintenance. It works well and is priced well.

Our hot tub is pretty easy to manage, chemical-wise, but it almost always need a little PH up. I struggled with the hot tub chemical balance until I read somewhere that if the PH isn't optimal, it's hard to get anything else right and I swear by that now. I tried another brand of PH up and it didn't seem to work nearly as well as this one.
