Calcium Indicators

Calcium indicator is a reagent used in swimming pool water testing, specifically to determine the calcium hardness level. It's a crucial component of test kits and it helps in maintaining balanced pool water chemistry. The indicator changes color during a titration process, signaling when the calcium level is within the desired range. It's used in conjunction with other reagents and a titration process to precisely measure the calcium concentration. Proper calcium levels are vital for pool health, preventing issues like scaling or corrosion.
