Good chemical additive.
0 of 1 found this helpful It raised the pH of my pool. It got cloudy at first but after two days it was clear again. I put 8 pounds into a 12,000 gallon pool

Size comment
These are good for people with small earholes. Hard to find, too.

Size is misrepresented
I wear a 6 ⅞ hat size, which is quite small. This hat is advertised as a size "medium." But it is so small I cannot even use it. It is several eighths smaller than a 6 ⅞. It is useless to me though it might fit Zippy the Pinhead.
