## Overview

Clorox Pool&Spa Alkalinity Increaser is a 5 lb granular formula designed to raise and stabilize total alkalinity in pool water, ensuring balanced pH levels between 7.2 and 7.6. This fast-dissolving product protects swimmers from irritation, prevents corrosion of pool surfaces and equipment, and reduces overall maintenance efforts. Trusted by thousands with a 4.7-star rating, it’s the smart choice for maintaining crystal-clear, comfortable swimming conditions all season long.

## Description

Clorox Pool&Spa Alkalinity Increaser protects your pH, protects your surfaces, and improves swimmer comfort by raising low alkalinity levels. Proper alkalinity levels in your pool help reduce pool maintenance. The granulated formula is simple to apply and dissolves fast. Test and balance your pool weekly to maintain clear water, longer lasting equipment, and comfortable swimming. Maintaining proper pH of 7. 2 to 7. 6 is not only easy, but can save your summer. If pH is too high, swimmers will suffer from red eyes and itchy skin, chlorine cannot disinfect water effectively and water becomes cloudy. If pH is too low, corrosion can ruin surfaces and equipment and water will burn swimmers' nostrils and eyes. Keep pool care easy by using the Clorox Pool app, the proper balancing product, and a regular maintenance routine.

Review: Great price (if you have free Prime shipping). Great product. Works better than baking soda (won't raise that pH as much), and just as well as the much more expensive alternatives you find for "alkalinity up" at the big chain pool stores. We've found all Clorox brand pool supplies, especially this and the Shock, to be functionally perfect at a much cheaper price than big chain pool store alternatives. Not always available at WalMart, we were happy to find it here on desertcart at about the same cost with quick delivery. Life is better and easier with desertcart Prime.
Review: Works great. Great price compared to pool store products.

A: Hi, We are the manufacturer of Clorox Pool&Spa products. The Alkalinity Increaser is not Cyanuric Acid or Stabilizer. If you have any other questions or concerns, please give us a call at 1-800-SOS-POOL.

**Q: Can this be used in a spa**
A: Hi. We are the manufacturer of Clorox Pool&Spa products. The Alkalinity Increaser could be used in a spa, however, the dosages on the bag are listed for pools so they would have to be modified to work in terms of a spa. 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 for spas, or just pools?**
A: Hi, We are the manufacturer of Clorox Pool&Spa products. The Alkalinity Increaser can be used in spas, however, the dosage chart on the back is written in thousands of gallons for pools, so the dosage would have to be adjusted. If you have any other questions or concerns, please give us a call at 1-800-SOS-POOL.

**Q: Is this ok for vinyl above ground pools?**
A: Hi, We are the manufacturer of Clorox Pool&Spa products. The Alkalinity Increaser is safe in use in an above ground vinyl pool. If you have any other questions or concerns, please give us a call at 1-800-SOS-POOL.

Like pH up, this is a basic chemical, no fancy blends of various complicated compounds. So why spend more? These Clorox spa chemicals have been the most cost effective I’ve found. The hardness increaser, pH up and this alkalinity increaser have all been excellent values. They are nicely granulated, and flow without undue caking. For convenience I do refill my original plastic containers from out spa starter kit. But these Clorox products are nearly half the cost of the spa shop and the lowest cost I’ve found so far. Storing the remainder in the resealable bags has not been a problem with shelf life either. Our spa is small so we use small amounts, this stuff will ladt use for a few years.
