ARM & HAMMER Clear Balance Swimming Pool Alkalinity pH Preservation Tablets White 1 Pack of 24

Great. Would purchase again.

I used this product only one summer (just installed a new above ground pool last July) and it seemed to work fine. I did not have any issues with the water at all. It stayed clear all summer until Fall when we closed it. We purchased an automatic chlorinator (highly recommend doing this) and the Arm & Hammer did help keep the water clear. I will use it again this year and see how it goes.

Like everyone says in the review, this product is poor. It came is as powder as supposed to be round tabs.

Guys, they're not chlorine tablets, and they don't replace your tabs. If you use these instead of your chlorine tabs you're gonna have a huge issue. They are meant to be used in conjunction with your chlorine regimen. Also, yes, they dissolve quickly - they're supposed to - it doesn't mean it isn't working. When adjusting your pH and alkalinity, you need the chemicals to actually dissolve for them to be effective. I have been using these for 2 years in addition to a chlorine tab in the floater and a gallon of liquid chlorine when the free chlorine gets low, and I haven't had a problem keeping the water perfectly clear and perfectly balanced, even in the summer when my water temp can get over 90. My box that was just delivered had all tablets still intact, but when they break, I just toss the pieces in the floater. Very happy with this fine

Product came with the majority of the tablets broken in pieces
