In The Swim Pool Shock - 68% Cal-Hypo Granular Sanitizer - 12 x 1 Pound

Price is fair and it's a effective item. My pool is about 16000 gallons and 1 bag a week works fine unless we get a lot of rain. Don't be concerned with the quality.

Great price for quality pool shock.

Used this stuff for the last two years. The trick is to dilute it in warm or hot water and let sit for about ten minutes then stir it with a stick then pour. It will get cloudy for about one to two days depending on how much you used. I like the cloudiness because I can see the chlorine circulation.

Does the job reasonably but not as good as local pool store product. Tends to take long to dissipate in the pool. Needs more product to raise chlorine level

Great Pool shock fantastic Product

Works great. We depend on it every year. It clears up water completely very wuickly.

This works just like any other 1 pound bag of shock. I have a 20 foot round above pool, waterline is about 4 feet tall. I decided to purchase online because it is a little less expensive and more convenient than going to the store. I believe if this is on subscription you get an additional discount. I may go through one bag every 10 days and that’s mainly because my pool water gets warm because it’s in the sunlight the entire day.

Works great for the pool!
