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

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

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

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

Great for the swimming pool

This works just as good as the more expensive brands at a fraction of the price. I use it mainly for my salt water pool but I can also use it for my bromine hot tub as well.

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.

All I needed for my barrel outside no more mosquito, very much durable
