Costco HTH Super Shock Treatment with Test Strips


Costco sells this HTH Super Shock Treatment for $45.99. Scroll down for photos. I saw this on the shelves about a month ago & the next week I went it was sold out. This goes the same for the Chlorine Tablets. The pool maintenance items are popular as summer is right around the corner. The temperatures are warming up & COVID-19 restrictions are being loosened. That means everyone is getting their pools ready for summer gatherings. I’ve only seen these 2 pool maintenance items at Costco: Super Shock & Clorox Chlorine Tablets. They are probably 2 of the most popular items & Costco sells out of them pretty quickly. Make sure to grab them while you can. Here are a few more details about this Costco Super Shock……..

  • Brand: HTH Super Shock All in One Treatment
  • 15 Count, 1 Pound Individual Bags
  • Cal Hypo Shock Product
  • Includes 15 Test Strips
  • Formula fights against Chlorine Lock
  • Kills Bacteria
  • Destroys Algae, Crystal Clear Results in 24 hours

Costco HTH Super Shock Treatment with Test Strips


This stuff comes pretty highly rated across all the popular online stores. What’s great is that it works in 24 hours, so you can get your pool in working order in just a few days. I found this in the middle aisle next to all the other pool items, but like I said, it went quickly. Costco doesn’t sell this online, so this can only be found in stores. I’d be curious to hear from any of you who have used this before & what the results were. Anyways, if you can’t find this online, or you want to buy a smaller container, or you want to check out some other HIGHLY RATED brands, make sure to check out the following links…….

Price: $45.99, Item Number: 1515008
