Local Pick Up Only
Lifeline #5 Calcium Hardness Increase 25lbs is a granular calcium chloride product used to raise your pool or spa's calcium hardness levels to the ideal range, protecting both surfaces and equipment from the damaging effects of soft (low calcium) water.
Key Features and Benefits
- Raises calcium hardness to the recommended range (typically 200–400 ppm for pools)
- Prevents corrosion of plaster, pool surfaces, tile grout, and metal equipment caused by soft water
- Helps stop foaming and surface etching
- Supports long-term pool or spa investment by preserving finishes and mechanical components
- Granular form allows easy and controlled dosing
- Compatible with all pool types (concrete, vinyl, fiberglass) and sanitizing systems
- Why Balance Calcium Hardness?
- Low calcium hardness leads to corrosive water, which can dissolve pool finishes and corrode equipment
- High calcium hardness can cause scaling, cloudy water, and reduced equipment efficiency
- Maintaining the right range ensures clear, balanced water and minimizes costly repairs
Dosage and Use
- Standard formula: 1.1 to 1.25 lbs per 10,000 gallons of water increases calcium hardness by 10 ppm
- For a 25lb container, that's enough to significantly adjust hardness in most home pools
- Test calcium hardness before application; ideal range is 200–400 ppm (consult manufacturer instructions for your specific pool finish/type)
- Broadcast product evenly over the water surface with the pump running for thorough distribution
- Allow water to circulate; retest after a few hours and repeat as needed until target range is reached
- Avoid adding large amounts at once to prevent overcorrection
Additional Details
- Calcium hardness increaser is safe for regular adjustment and is a standard part of pool opening or refill routines
- Product is not hazardous and ships easily; store sealed and dry
- Excessive calcium cannot be lowered chemically—only through dilution with fresh water
Lifeline #5 Calcium Hardness Increase 25lbs provides an effective, industry-standard solution for keeping your pool water balanced and surfaces protected.
