This product does what it is supposed to do however the cost is ridiculous compared pre covid prices. I believe that all these pool products are priced too high and taking advantage of people.

i always use this brand, but this particular 6 pack must've been old or not stored properly the granules didn't sink nor help my pool.. just got a new pack from another seller and it was much better. i used them not even thinking about it, until it was too late.

This was not the product I wanted but what was recommended for the substitute. I assumed they were created equal,I was wrong. They are normally 16oz/ 1lb bags these are less, so it requires more to treat my pool. Then the product immediately became cloudy when added to pool water. it was hours before the cloudy mess went away. thinking it was now safe to swim I entered the pool only to find the residue was all settled at the bottom and it came back cloudy when the water was moved. I have brushed, ran my vacuum and brushed again same result. My pool is balanced and crystal clear as usual unless you are swimming. I don't know how long it will take to filter this fine chalk from the water. Very frustrating!

I bought 6 to last several weeks. My pool requires 2 packets at a time on a weekly basis, but I was starting with a greenish water and anticipated the need for additional shock. I put in 2 in the evening with the pump running continually. In the morning, it was overcast and raining, but the 2 packets of shock didn't touch the clarity of the water at all. I tested my PH, CYA and the rest of the levels. My PH was too high, but CYA looked perfect. I added a SUPER Algaecide, PH balancer and 2 more bags of shock. Still green and it still says that is no free chlorine in the water. Basically, I used all 6 bags of shock and did not see any results. Don't waste a penny on this product.
