Hydrochloric (muriatic) acid is added when the controller has deemed the pH to be too high.  A electrically actuated peristaltic dosing pump transfers acid from a reservoir into the pool water return.  The relatively small amount acid flow relative to the flow of the return ensures significant dilution.

Calcium hypochlorite (chlorine) is added when the controller has deemed the ORP to be too low.  A PowerBase Model 3150 chlorinator is responsible for adding chlorine by dissolving "Accu-Tab" solid tablets in water.

It has been observed that the chlorinator has a tendancy to over-shoot.  Therefore, the ORP setpoint on the controller is set lower than otherwise might be expected to minimize this over-shoot.  The net result is a proper amount of chlorination in the pool.
