Doheny's 68% Cal-Hypo Pool Shock, Fast-Dissolving Granular Chlorine, 12 x 1 lb Bags

Another season underway using Doheny quality pool chemicals. I use their shock and 3 inch chlorine tabs and pH Up and the pool is ready for swimming within 7 days of opening and shocking. During the season, never a problem. And their prices are so much lower than any pool supply store on Long Island. With Doheny ( and my old Dolphin robot) maintaining my pool is a breeze.

I purchase cases of 1lb bags of shock for my inground pool. Two bags each week and it remains crystal clear throughout the summer. I stock up at the beginning of the season when Doheny's offers great prices. Delivery is fast and reliable. Recommended!

Dohenys products are by far the best pool products that i have ever used..They last for a long time. My pool looks amazing and the pool water smells so good amd clean. I have very hard water and i usually can smell it on my clothes snd skin when i get out of my pool. Bur with their products my pool water doesn't have that awful smell. The shock turned my pool blue instantly. the 3 in tablets i put in my skimmer and my basket on the side. they last forever, ehen i tirn my ppol on you can snell the cleanness of the water. it makes it soft too, if you habe hatd water you know what i mean. my hair doesn't feel like straw when i get out either. i will always use their products, others are a waste of money.

The chlorine tabs are very competitively priced compared to our local pool supply store. The delivery is free and very fast. This product works very well.

The products work as expected. Will have to use them a little longer to understand how well any future use. The beginning of the swimming season won't begin until next month, so there is more time the products have to be used.

This has been the only shock I have used for at least 15-20 years. We live in the woods and every year the pool is filthy no matter what. Within less than a week shocking the pool we see the bottom and by weeks end everything is great

I've bought this pool shock for several years now, and it works great. Combining this with chlorine tablets, the pool water gets crystal clear and algae growth is minimal. I will continue using this product in the future.

I can count on this shock as being potent enough to get the job done right. Alge is gone in a flash. Heavy rain? Just drop in a pound of shock and pool water stays crystal clear! Love it!

There's nothing wrong with the product, it's excellent. But it used to come ina handy plastic bucket. Didn't have as much c9ncern over dampness effecting it. Now it comes in a cardboard box!

This shock permanently stained our liner which now needs be replaced. After use, when shock settled at the bottom we were unable to vacuum off bottom even after manually scrubbing. We've had our pool for 19 years and never had an issue until the use of this shock. Needless to say we will not be purchasing again.
