Automated dosing

Automated dosing pairs with the chemical controller to inject precise volumes of liquid chlorine (sodium hypochlorite) and muriatic or sulfuric acid as readings drift from setpoint. The pumps run for seconds at a time, multiple times per hour, holding chemistry within tight bands. Well-tuned automated dosing eliminates the chlorine-spike-then-burnout cycle of hand-dosing and reduces total chemical use 15–30%. Failure modes include empty drums, clogged injection ports, and out-of-cal probes — daily walk-through still required.
