Features

  • 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

  • Good product
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!

  • Coronavirus drives up the cost of water to make liquid bleach! News at 11.
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. ... show more

  • Great for cleaning washing machine rubber gasket
Had a terminally gross washing machine door gasket that nothing could get the deep mold out. Mixed about 1/10of of this bag with a little water, smeared it on the gasket and let it sit for 30 mins. Ran a high temp wash and boom...mold was 99% gone. Saw some Youtube videos that suggested this and it worked like a charm. Saved me buying a $200 new gasket and a pain in the butt instal ... show more
