I’ve had good results using the Pool Shark 68% Cal-Hypo shock. It dissolves well when used as directed and clears up cloudy water quickly. The higher 68% calcium hypochlorite concentration means you don’t have to use as much product compared to weaker shocks, which makes it a good value. After treatment, my pool water looked noticeably cleaner and tested within the expected chlorine range. The packaging kept the product dry, and the individual bags were easy to store and use without making a mess. Overall, this is a dependable pool shock that works effectively for routine maintenance or after heavy pool use. If you’re looking for a strong cal-hypo shock at a reasonable price, this is a solid option.

Easy to use, doesn’t have that strong terrible smell as other products and balances water easily - our pool gets used constantly in the summer with pastries and our daughters high school friends - this shock works great!

This shock is AMAZING. I recently purchased a home with a pool that hadn’t been open for 2 yrs and after putting 10 scoops of this in the pool it began clearing the water up within hours. I was literally amazed at how quickly it worked. It even got rid of the nasty algae on the walls and bottom of the pool with me having to scrub it. I will continue using this for my inground pool.

It is a good price, but does not dissolve. No matter how much I put in and how many times I sweep it- it won't dissolve. Causes the water to look cloudy and settles at the bottom. I sweep after adding it, it looks great. An hour later, it looks like I didn't sweep it at all. I have never had this issue before. Super weird. Probably wouldn't buy it again. Too much work and I end up having to vacuum the pool way more than I should.
