Frequently Asked Questions
Q: Why is calcium hardness important in pool water?
A: Low-calcium levels can cause water to become corrosive, damaging pool surfaces, tile grout, heaters and metal fixtures. Proper levels prevent etching and maintain equipment life.
Q: How do I know if I need to use this product?
A: Use pool test strips or a test kit to check calcium hardness. If it’s below 200 ppm, use Poolife™ Calcium Plus to raise the level into the recommended range.
Q: Will this cloud my water?
A: No. When applied as directed, Poolife™ Calcium Plus dissolves easily and won’t cloud pool water.
Q: How often should I test for calcium hardness?
A: At least once per month or after a large water refill, rainstorm or whenever balancing your pool.
Q: Can I add this product at the same time as other balancing chemicals?
A: It’s best to add Poolife™ Calcium Plus separately from other chemicals like pH adjusters or alkalinity increasers. Wait several hours between treatments to avoid chemical interaction or clouding.
Q: What happens if I add too much calcium?
A: Excess calcium hardness (above 500 ppm) can lead to scaling on pool surfaces and equipment. Always test water before dosing and use the included chart for accurate application.
Q: Is this product safe for saltwater pools?
A: Yes. Poolife™ Calcium Plus is safe for saltwater systems and is essential for protecting salt cell generators and heaters from corrosion or scale buildup.
Q: Can I swim right after using this product?
A: Yes. Once the product is fully dissolved and has circulated for at least a few hours, swimming can resume — no special waiting period is required.
