ARM & HAMMER Clear Balance Swimming Pool Alkalinity pH Maintenance Tablets, White, 1 Pack, 24 Count

Local Walmart was sold out. I use 3 to 4 tablets a wk in my 27 foot round pool. Anyways, I turned to Amazon and bought these. Was worried about them being broken like a lot of people complained about. But nope perfect condition. if they are just broken I can still use. But when they turn to powder they are useless.But these came fullu intact. Maybe it was because it was an over night delivery and not on a truck for hours.Happy with my purchase

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

Takes the labour out of keeping the pools PH balanced, add one with the new chlorine tablet and voila. Second year with no pool issues. Bought a sand filter. Use this once a week with the chlorine tablet and run sand filter 2 hours a day at night. And a weekly shock. Pool gets heavy use and it stays clear and balanced.

I used this after my pool turned green from algae. Within 24 hours, the green was gone, which was great. The water did turn cloudy afterward, but that’s expected when algae dies off. After 3 days, it’s still a bit cloudy, but much better.Overall, this product worked well to kill the algae and balance the water. Just be aware the cloudiness may take a few days to clear up.

I use these in my swimming pool. 2 tablets a week keeps my P. H, balanced in my pool nice and blue.

We were having issues with high PH and Alk -but our chlorine was supper low despite using so much of it. We are in high heat area - so we’ll be using this product in conjunction with our normal chlorine regime. We had to use double the amount for our pool size to get our numbers back to normal- now that we’re back on track we can use the recommended tabs moving forward.

Hi! Just a quick review of this product and my thoughts.My pool is 18 kSolar keeps it in the high 80s/low 90s. It cools down overnight. It doesn't stay at that level. Only during the day peak hours of sun.It gets a lot of sun. I am constantly putting chemicals in it because the sun just eats them up.I put four tabs in last night and they're gone in the morning.I have bought several of these boxes, but I guess I haven't been paying attention to how quickly it dissolves.With that said, my pool has never looked better. Haven't had to adjust the alkalinity or the pH.I'm not an expert, but it's doing something.I check the floater about once a week. I just never knew it was dissolving so quickly.But I do have to say that when my solar goes off, it makes some foaming stuff for a little bit on the pool's surface. I wonder if that's perhaps the product.I don't know, but my pool looks good. I just wonder if it's worth the cost.

Works great for my above ground pool to keep the PH in balance.
