Frequently Asked Questions
Q: What does Sirona™ Calcium Booster do?
A: It raises calcium hardness levels in spa water to help prevent foaming, scaling and equipment corrosion.
Q: When should I use Calcium Booster?
A: Use when your spa’s calcium hardness is below 200 ppm, as low hardness can cause foaming and damage to equipment.
Q: How do I test for calcium hardness?
A: Use spa test strips or a liquid test kit that measures hardness levels in ppm.
Q: How much will Calcium Booster raise hardness?
A: ¾ oz. per 500 gallons raises calcium hardness by about 10 ppm.
Q: Can I add Calcium Booster directly to the spa?
A: Yes, simply add it directly with the circulation system running — no pre-dissolving required.
Q: Is this product compatible with all sanitizers?
A: Yes, it can be used with chlorine, bromine and mineral-based systems.
Q: Will high-calcium hardness harm my spa?
A: Excessive hardness (above 400 ppm) can cause scaling, so it’s best to keep levels between 200–400 ppm.
Q: How often do I need to add Calcium Booster?
A: Frequency depends on your source water. Check hardness levels regularly and adjust as needed.
