Description

Kick off your swim season with confidence and keep your water sparkling clear all year long with this premium 2-step bundle from In The Swim. The Ultimate Pool Start-Up Chemical Kit (for pools up to 35,000 gallons) delivers everything you need for a smooth, hassle-free opening — clearing cloudy water, eliminating algae, removing scale, controlling metals and stains, and balancing essential chemical levels. Once your pool is open and refreshed, Pure Clear + No Phos takes over as your weekly maintenance hero. This non- toxic, eco-conscious formula removes phosphates and non-living organic contaminants that lead to cloudy water, waterline buildup, odors, and added filter strain. Together, these two products create a streamlined, sustainable care system that helps you open your pool smarter, maintain it easier, and enjoy cleaner, clearer water with far less effort.

  • great starter package
Style: Kit + Chlorine Size: Basic - 7.5k gallon
This was a great starter kit. We got our first pool and I was so lost on where to even start. It was a great package to get me started. There are a few things that I am not sure if I will end up needing them but I am glad I got it to get me started.

  • Working as it’s supposed to
Style: Kit + Chlorine Size: Basic - 7.5k gallon
This was shipped quickly and arrived in two separate boxes and two different days. I bought this for my 700-gallon little pool. The chlorine tablets are 3 inches so I will probably use one every other week or I will break them up and use 1 a 1-inch amount once..

You get what you pay for. Most of the tablets came broken. They were wrapped individually which was good.
