  • 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

  • Meh I didn't need most of this stuff.
Style: Kit Only Size: Basic - 7.5k gallon
The stuff works but the kit doesn't really have the chemicals you need to maintain your pool. Maybe it is my fault for thinking the opening kit would be what you need to open and maintain.
