## Description

"Clorox® Pool&Spa™ pH Up raises low pH in your pool so you can maintain a beautiful, swim-ready pool. The granulated formula dissolves fast, and the easy pour application bag makes raising your pH simple, and fast. Low pH in your pool can cause red, irritated eyes and expensive corrosion damage to your pool equipment. Use this pH increaser as needed to achieve a suitable range of 7.2 to 7.6 to keep your water swim-ready and clear. Intended for use in both traditional chlorine and salt chlorine pools. Test and balance your pool weekly with the Clorox Pool app to maintain clear water, longer lasting equipment, and comfortable swimming. Maintaining proper pH of 7.2 to 7.6 is both important and easy. Important, because if pH is too high, chlorine cannot effectively sanitize and disinfect your water and water will irritate your skin and eyes when you swim. If pH is too low, corrosion can occur and the pool water will irritate your skin. "

## Questions & Answers

**Q: How much do I use for a spa? My spa is 460 gallons. The packaging and app only provide instructions for pools.**
A: Well, when I do stuff like this, I normally do some simple math doing a proportion, then cross multiple and then divide.  So if this product is 4 lb per 10,000 gallons, and your pool is 460 gallons, your proportion would be: 4/10000 = X/460.  Cross multiple and you would be 10000X = 1840.  Divide 1840 by 10000 which is x=.184.  Now multiple that number times 16 ounces and you would get 2.944 ounces.  So you add about 3 ounces.  You can use a small kitchen scale.

**Q: If this product is for pool and spa, where are the spa dosage instructions? Do they scale from 10,000 gallons to 400?**
A: Hi. We are the manufacturer of Clorox Pool&Spa products. Clorox Pool & Spa is our brand name and is not meant to be a description of each individual product. Also, the pH Up only has dosing for a pool listed, but can be broken down to apply to a spa as well. Please give us a call at 1-800-SOS-POOL if you have any further questions. We are available Monday to Friday from 8:00am to 6:00pm EST.

**Q: Is this compatible with Aqua Silk/biguanide pool sanitizer?**
A: Hi. We are the manufacturer of Clorox Pool&Spa products. The Clorox Pool and Spa pH Up can be used in a pool that uses biguanide as the sanitizer. Please give us a call at 1-800-SOS-POOL if you have any further questions. We are available Monday to Friday from 8:00am to 6:00pm EST.

**Q: I just put some in our above ground inflatable pool and the water is very cloudy! did i put too much? if so, how do i adjust so it's not cloudy?**
A: Hi. We are the manufacturer of Clorox Pool&Spa products. High pH products can have the potential to knock material like calcium out of solution which can cause cloudiness. At this point you'll want to make sure the pH is kept in range, preferably 7.2, and let the filter run as often as possible to get some of the material filtered out. Please give us a call at 1-800-SOS-POOL if you have any further questions. We are available Monday to Friday from 8:00am to 6:00pm EST.
