Pool water looks beautiful

I usually pick these up at the store, but this time I had them delivered. excellent service online and this product works wonders in the pool. It seemed to keep it clean and clear much easier with these tablets.

Hard to open the first time

Dissolves without using too much. Bucket is nice size and makes it easier to work with. Somewhat hard to open the first time. Do not lean over bucket when you open it. Fumes from the cholorine are very strong
