Frequently Asked Questions

What is the difference between Hardicol (AP254) and Calcicol (AP252)?

Hardicol (AP254) measures total hardness, which includes calcium and magnesium. Calcicol (AP252) measures calcium hardness only. For pool water management, calcium hardness is the primary parameter monitored, but total hardness testing is useful for understanding the full mineral content of the water.
