About this item

  • EASY SHOCK TREATMENT FOR FAST RESULTS - After a busy weekend of swimming, your pool needs a quick refresh. Pool Shark fast-dissolving granules make shock pool treatments easy. Just measure it out, toss it in, and watch your water turn from cloudy to crystal-clear in 24 to 48 hours.
  • CLEANS & CLEARS POOL WATER COMPLETELY - Nothing feels better than stepping into a pool that looks clear and smells fresh. With 68% calcium hypochlorite, our swimming pool chlorine shock granules kill bacteria, fungi, and algae, so you can enjoy safe, clean water with zero cloudiness.
  • EXACT DOSING NO MATTER YOUR POOL SIZE - Not sure how much chlorine pool shock to use? 1 pound treats 10,000 gallons of water. Safely use these pool chemicals for inground pools that are standard size (10,000-20,000 gal), all the way up to large community pools (100,000-200,000 gal).
  • COMPATIBLE WITH ALL POOL TYPES - You can use our 68% cal-hypo pool shock for an inground pool and also use our pool shock for above ground pool treatments, spa, hot tubs, vinyl-lined pools, saltwater systems, and all public and residential pools outdoors or inside facilities.
  • PREMIUM 68% CALCIUM HYPOCHLORITE - Our formula contains 68% active calcium hypochlorite, delivering stronger results than standard chlorine products. When you need fast reliable sanitization, trust Pool Shark to get the job done right the first time.
  • If you receive items with a different label, Bucket, than what is pictured, please note that any such alteration is purely cosmetic and your Cal Hypo will still function exactly as described

Works just as it should, but more expensive than I pay at big box stores.

Good product. Cleared pool very fast. Had to run vacuum to mix up from the bottom. Has a little trouble dissolving, but that doesn’t stop me from using. Will purchase again!

I just took a picture of my pool so I’ll give you an idea how big this pool actually is and I try with all my heart to find the best deals possible online whether it’s with a pool company or whether it’s Amazon and I found the best prices on Amazon so here we are with a massive huge Container of shock which should last me at least four months this time it’s a massive container and worth the penny. Anybody who has a pool no darn well you need shock so you can’t live without it. I might as well get it the best. Best price possible

Since the Coronavirus caused the price of chlorine bleach to jump from less than $1/gallon to over $2/gallon I have searched for a cost effective way of bleaching shop rags and doing general shop floor cleaning. Tablets are a pain to dissolve and measure out effectively for small projects. I measure out the contents of these packages to get the right chlorine content to meet my needs. Bleach manufacturers must be using imported water to produce bleach to justify current prices of liquid bleach.
