ARM & HAMMER Clear Balance Alkalinity & pH Maintenance Tablets for Pools & Spa, 24 Count

I used it for 2 years in the summer for an above ground pool. I used it along with the "Pool Essentials Chlorinating Liquid for Swimming Pools Liquid" and pool filter and kept the water clear. I had to put it once a week. The tablet dissolves almost all the way and a day after you put it, you will see a residue patch of what didn't dissolve the next day. I just would swirl around the residue, and it would dissolve completely.

i dont know what id do without it. i was always having to fight algae because the sun shines on my pool ALL DAY and it was frustrating and always struggling with chemicals for ph and alkaline and i was using chlorine so fast so I tried these and WOW!!! I will never go without these again. im not having to struggle anymore with fighting the sun and the water and im using lass chlorine and more relaxed and can enjoy more time in the water and OH YEAH!!! NO MORE EYES BURNING. im never gonna be without this again as long as i can help it. please don't ever stop making it. its a big lifesaver and lifes stressful enough without stressing over algae instead of enjoying the water.

They work well in our 18' round pool. I put 2 chlorine pucks and 2 of these pucks in the floater once a week and our pool chemicals are stable and where they should be.

works great 1 tablet once a week round 18x18 and 1/2 by 14x14 depending how much you use your pool we have both pools with a slide between the kids love it and adults too. you can use the pool as soon as you put in a tablet no wait time

We have a 15ft x 52 inch round pool, 1 Clear Balance in a floater and 1 chlorine tablet in another floater each week is all that is needed for a crystal clear pool all season.

nice option to replace bags of baking soda. all I use is these and 3" chorline tablets, occasional shock. 18x36 pool. these make it easy to maintain clear water

These tablets are easy to use and they really help keep the pool water very clear. We are happy to have discovered them, and Walmart always carries the exact products we need!

I am no chemist. Historically, our above ground pools did better when I didn't mess with them. We had an inground installed this year and I got these tablets to maintain between our scheduled weekly services. It's super easy to drop a few in the opposite skimmer basket of the chorine and they keep the pool so clear!

These questions are hard to answer I wrote in the beginning we have not gotten the order it was delayed and it said today but still nothing. The product works great especially when it rains alot, add to pool crystal clear. So when we get it it will be great hopefully tomorrow sometime.

I would definitely recommend this product because it works well but when it was delivered, all the tablets were busted so bad that most of the box was just dust. Little expensive to have it come all broken.
