Calcium buildup on pool tile — Hilversum, Noord-Holland
A white, chalky crust along the waterline tile is calcium scale — hard mineral deposits left behind as pool water evaporates. High calcium hardness, elevated pH, or excessive alkalinity accelerate the buildup, and once it bonds to tile or stone it resists normal brushing. A pool and spa technician tests the water chemistry, acid-washes or bead-blasts the affected tile, rebalances calcium hardness and pH, and may apply a sequestering agent to keep minerals in solution and prevent recurrence.
