I use this brand and product every year in my above ground pool. Good buy. Disolves fast, keeps my pool clean. And works great my water looks clean and clear. Love how easy it is to use and the appearance of how crystal clear my pool looks. Great value. I usually dont need to use a full package or 1 a week, so this pack will last me all season probably.

I have a 24’x48” above ground pool. I throw 2 bags of this in whenever the water starts looking less than amazing and it clears the water up almost instantly! The bags are hard to open and you need scissors and it’s definitely not cheap but I’d rather pay for this than have green water

5.0 out of 5 stars It works.
Reviewed in the United States on July 19, 2024
Product works good but it does make the water quite a bit cloudy so you will probably need clarifier or some flockulant if you're using a lot of it.
