The Cal Hypo based formula in HTH® Chlorine Granules Ultra 5lbs provides chlorination without adding extra CYA for beautifully clear water all season. The all-in-1 action also kills bacteria and algae, clarifies and softens pool water, prevents stain and scale and provides a filter aid for the ultimate convenience in DIY pool care. This product is great for all pool types including vinyl-lined swimming pools and salt water systems. </p><p>How To Use HTH® Chlorine Granules Ultra Follow the on-pack dosage instructions according to the size of your pool. While the filter pump is running during the evening, use a clean, dry scoop to apply chlorine granules evenly over a wide area in the deepest part of the pool. Use a brush to disperse any granules that fall to the bottom of the pool. When granules have completely dissolved, use HTH® 6-Way Test Strips to test free available chlorine (FAC) residual. Do not enter your pool until the free available chlorine residual is 1 to 4 ppm.</p>
