Prevent Stains, Rust, & Scale In The Swim Stain Away for swimming pools prevents surface stains and discoloration of water. It also helps disperse stains and scale from pool surfaces while controlling iron and other metals. Spring Stain Away is great to use at pool opening when filling the pool as it will help control the minerals and metals in the fill water, protecting the pool against staining and scaling. Clear Cloudy Water Fast In The Swim Clarifier for swimming pools helps coagulate dirt and other suspended particles clearing cloudy pool water. Adding In The Swim Clarifier also increases your pool filter's efficiency. Fast acting and biodegradable, this water clarifier does not affect the chemical balance in the pool. Powerful 68% Calcium Hypochlorite Granular Chlorine Shock The Basic Start-Up Kit includes a single one-pound bag of calcium hypochlorite chlorine pool shock that will kill bacteria and destroy organic contaminants in the water. This powerful pool shock is great to use for spring pool openings and ideal for a quick chlorine boost. Algae Beware! Algaecide for control of algae and algal slime growth in swimming pools is also included. This algaecide is non-metallic and does not cloud or stain the pool when added. It is very effective at preventing and treating many types of algae including green and yellow mustard algae. Stop Grease, Grime & Waterline Scum The Sun Sorb attracts and absorbs lotions and oils to improve water quality while reducing stress on your pool filter. It absorbs up to 40 times its weight in residual Review: Solid startup kit - This basic pool opening kit was a great, no-stress way to get my pool up and running for the season. It comes with everything you need to get started, which is perfect if you don’t want to guess what chemicals to buy separately. The instructions were easy to follow, and the kit helped clear up my water pretty quickly. It’s sized well for smaller pools (up to 7,500 gallons), so it worked perfectly for my setup without feeling like I was over- or under-treating. I also like that it simplifies the whole process—just open, follow the steps, and you’re on your way. It’s especially helpful for beginners or anyone who wants a convenient all-in-one solution. Overall, a solid starter kit that takes the confusion out of opening your pool and gets the job done. Review: Great Start Up Pool Package - I have used In The Swim products for our above ground 15' by 24' pool for a few years now. I have always been very happy with the results. The start up kit is perfect and you save much money instead of buying individual products that you must measure per pool size and then store the remainder. ## Features - Basic Start-Up Kit up to 7,500 Gallons Includes: 1 pt.
