Clorox® Pool&Spa™ Swimming Pool Alkalinity Increaser, Keeps pH Balanced, 5LB (Pack of 1)

Works, and much cheaper than pool stores. I fill the old bottle with some of this as needed.

Good price for a pool necessity for balancing alkalinity. Delivered same day!

This works great. One package had small tear on arrival, but it was in another box so wasn't a huge deal. The product itself works awesome. Chart on back works great for getting alkalinity to where it needs to be (which also increased PH as expected to where it needed to be). No issues at all with it as far as clarity, dissolve rate, etc.

Product is good but packaging was damaged on arrival. Thankfully not much spilled out

Works perfectly in the pool and I don’t use as much ph additives or other chemicals.

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.

I've been using Pool Clearly Powder for past summer and it's been a game-changer for my pool water clarity. After adding the powder as directed, I noticed a significant improvement in the water's appearance within minutes. The cloudy or hazy look was completely gone, and the pool looked crystal clear.The powder is easy to use and dissolves quickly in the water. I haven't noticed any negative side effects on my pool equipment or the water's pH levels.If you're struggling with cloudy pool water, I highly recommend trying Pool Clearly Powder. It's a reliable and effective solution for achieving a sparkling clean pool.

Great for the swimming pool
