Product details
The LaMotte 7041-G is the Calcium Hardness 2 reagent in a 30 mL bottle. It is a refill for LaMotte calcium hardness testing, not a complete kit.
Why calcium hardness is worth testing
Calcium hardness sits alongside pH and alkalinity in the balance of pool water. Too little calcium and the water goes looking for it, etching plaster and attacking grout. Too much and it drops out of solution as scale on surfaces, heater tubes and salt cells. Getting a number you can trust is the first step in either direction.
Keep reagents fresh
Test reagents have a working life. Age and heat both change them, and a drifted reagent gives a confident looking result that happens to be wrong. Replacing bottles on a schedule is cheaper than chasing a chemistry problem that was never there.
