LifeLine Calcium Hardness Increaser 15lb LifeLine Calcium Hardness Increaser 15lb is a granular calcium chloride product used to raise calcium hardness in pool water, helping prevent corrosion, etching, and other damage caused by “soft” or under‑balanced water. By keeping hardness in the recommended range (commonly about 200–400 ppm, minimum around 150 ppm), it supports long‑term protection of plaster, vinyl, and equipment while improving overall water balance. Key features & benefits Durable calcium protection helps stop water from leaching calcium out of plaster, grout, concrete, and some vinyl-backed surfaces, reducing pitting and structural wear. Optimized water balance works alongside pH, alkalinity, and sanitizer to keep water chemistry stable and easier to manage. Equipment longevity by reducing corrosive conditions that can attack heaters, ladders, handrails, and metal fittings when hardness is too low. Large 15 lb size is ideal for full openings, large pools, or step‑up corrections when hardness is significantly below target. Use & basic dosing approach When to use: At opening, after significant water replacement or heavy rain dilution, or whenever testing shows hardness below the recommended minimum. Typical target range: Many pool pros recommend keeping calcium hardness between about 200–400 ppm, with a minimum around 150 ppm to avoid corrosive water. General dosing concept: Test calcium hardness first with a reliable kit. Calculate how many ppm you need to raise based on pool volume. Broadcast measured product around the pool with the pump running, allow to circulate fully, then retest before adding more to avoid overshooting and potential scale. LifeLine Calcium Hardness Increaser 15 lb fits neatly into a professional balancing program, giving you a simple way to protect your pool surfaces and hardware while supporting clear, comfortable water.
