In The Swim Di-Zap Multi-Shock 24 x 1 lb. Bags F135001024AE

Works great. Just use one bag around your pool and it does exactly what it's supposed to—clears the water fast and leaves the pool looking super clear. No lingering cloudiness, just clean, sparkling water. Solid product, easy to use, and delivers the results you want. Highly recommend if you need a reliable multi-shock.

The product itself has always been awesome, I use 1) 1lb. bag a week and 2) 3 inch chlorine tablets in the floater a week, with the pump/filter on a timer circulating 8hrs a day. The water stays perfect in my 24ft above ground pool. "In The Swim" prices and service has always been unbeatable, my recent order for Di-Zap was apparently lost in transit, I promptly received personal attention from a representative and it was shipped a second time which I received in a couple days, Thank You.

WE USE THIS EVERY YEAR. GOOD STUFF, NO COPLAINTS EXCEPT THE PRICE OF POOL SUPPLIES NOW DAYS WITH EVERYONE IT SEEMS. JUST CRAZY

I have had a fiberglass pool for 24 years now. I switched over to Di Zap two years ago. I no longer have the chalky residue I always got from the other shock products I had tried over the years.

Pool opened and water a light green, needed to be super chlorinated without increasing calcium level, very effective, expensive but will purchase again.

Most potent shock I've ever seen! Works great!

Works great, fully dissolves.

Worked really well at settling the phosphates and clearing the pool.

Haven't used product yet as just recently found box dumped on road.

Im glad I got the small pack to see if this brand was any good. Idk if this was old or what, but it didnt work at all.
