Your swimming pool water is cleaner & safer when your water chemistry is properly maintained. Maintaining the water chemistry of your swimming pool is possibly the most important aspect of pool care and can even save you money. Chlorine tablets are one of the key chemicals to maintaining your pool water, and 3 inch chlorine tablets are the most popular method of water sanitization among long-time pool owners. 3 inch tablets are thicker than other pool chlorine tablets, allowing them to dissolve slower and protect your pool water for longer. Moreover, 3 inch chlorine tablets are the ideal size for chlorine floaters or automatic chemical feeders. Powerful 90% Available Chlorine Sanitization and disinfection is the most important aspect of good pool water chemistry, and powerful In The Swim 3 inch chlorine tablets are 90% available chlorine, and sun-stabilized, to make it easier to maintain any outdoor pool. Our chlorine tablets are made with 99% Trichlor, without fillers and binders found in cheaper tablets that dissolve too rapidly and gum-up a chlorine feeder. Slow Dissolving Chlorine Tabs Slow dissolving 3" chlorine tablets are used to deliver a daily dose of chlorine to your pool water, so your pool has a constant and consistent level of chlorine. These jumbo chlorine pucks help you avoid peaks and valleys or inconsistent chlorination, a common occurrence when using granular or liquid chlorine to sanitize a pool. Having balanced pool pH and Alkalinity levels also makes your swimming pool water safer and cleaner, helping increase the effectiveness of the chlorine sanitizer in the water. Ideal Size for Floaters or Automatic Chlorinators In The Swim pool chlorine tablets are very effective and easy to use, but should not be put into the skimmer basket as doing so can cause potential damage to the pool equipment over time. Instead, place chlorine tablets into a chlorine floater or automatic chlorine feeder for convenient and reliable distribution. Use enough tablets to maintain a consistent chlorine level of at least 1.0 - 2.0 ppm, as verified by your pool test kit or strips. Each slow-dissolving chlorine puck adds approximately 5.5 ppm of chlorine per 10,000 gallons over several days. On average, most pools use about one 3 inch tablet for every 5,000 gallons of pool water, replaced every 5-7 days. Water temperature, water chemistry, pool usage and weather conditions can affect this amount. Keep Your Pool Water Safe for Swimmers Choosing the right swimming pool chlorine tablets is a very important decision, as they help keep your family safe from bacteria and other organic contaminants in your pool water. In The Swim pool chlorine tablets dissolve slowly into your pool water to kill bacteria, algae, and other organic contaminants. Read our chlorine tablet reviews -- many people say that In The Swim has the best 3 inch chlorine tablets to keep pool water safe for swimmers and help maintain water clarity. In The Swim slow dissolving jumbo tablets efficiently sanitize, providing reliable long-lasting protection for your swimming pool water. You can rest easy knowing your family and friends will be safe from bacteria and other organic contaminants for a healthy and clean swimming experience every time.
