  • Great product
Style: Kit Only Size: Basic - 7.5k gallon
I’ve been using In The Swim Pool Basic Opening Chemical Kit for a few seasons now, and it never disappoints! This kit has everything needed to get my pool up and running after winter. The instructions are clear and easy to follow, making the entire process stress-free. The shock is powerful and does a great job of eliminating any leftover bacteria and algae from winter. The algaecide helps keep the water crystal clear, and the stain and scale preventer ensures my pool equipment stays in great condition. Within a day or two of adding the chemicals, my pool is sparkling and swim-ready! Another great thing about this kit is the value—it’s much more affordable than buying all the chemicals separately. If you’re looking for a reliable and cost-effective way to open your pool, I highly recommend this product. Would definitely purchase again! ... show more

  • Great value! Would buy again.
Style: Kit Only Size: Basic - 7.5k gallon
Everything came just as pictured. Chemicals did their job well! Great value for the price. Has lasted us all summer with an above ground best way instant set pool that is 12' by 3' ft. Good instructions for a newbie in pool maintence. Also love that it comes with the oil absorber spunge! We have a manual vacuum and pool skimmer so that helps a lot too. ... show more

  • Big help for first time pool opening
Style: Kit Only Size: Super - 35k gallon
Came with almost everything needed to open our pool. Wish they offered some brushes to make it an entire package. But worked well for opening and upkeep for about 1 month so far.

  • Makes Pool Opening a Breeze
Style: Kit Only Size: Super - 35k gallon
The In The Swim Pool Super Opening Chemical Start-Up Kit is a lifesaver for opening my pool each season. It includes everything I need to get my pool water clear and balanced, saving me time and effort. The instructions are straightforward, and the products work efficiently to eliminate algae and cloudy water. This kit is suitable for both above-ground and in-ground pools, and it covers a large capacity—up to 35,000 gallons. It’s a great value for the quality and quantity of the chemicals provided. My pool is ready for swimming in no time after using this kit! Highly recommend this for hassle-free pool opening. ... show more

  • Great price and wonderful results
Style: Kit Only Size: Deluxe - 15k gallon
AlwYs use a start up kit prior to opening your pool. It aids the chlorine and clears any crazy stuff in your pool. Really enjoy using Amazon for this , I went to intheswim.com and found that they were a bit higher in price than Amazon.
