    • Cost effective
Size: 1 Count (Pack of 1)
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. ... show more

This was very easy to use it dissolved very well and balanced the water as I needed it after I used this product I tested the water and I was right on with all of the items I was testing it for. It made the pool sparkling clean, and this will be a go to product.

    • Great product! Low-cost "alkalinity up" product. New Clorox pool products are great!
Size: 1 Count (Pack of 1)
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 Amazon at about the same cost with quick delivery. Life is better and easier with Amazon Prime. ... show more
