    • 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

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
