The ORP graph shows the ORP measurement over time. The graph shown contains two days worth of history. Certain events, marked by numbers, can be identified: | |||
# A valley indicates a ORP trend direction change. This typically occurs when chlorine is added to the pool. | |||
# Overshoot and leveling-off is common overnight, as a lack of UV (and to some extent, pool occupants) prevents the rapid breakdown of chlorine in the pool water. | |||
# Two events are identified in this marker. First, the gradual drop in ORP as the sun hits the pool (starting at about 7:30 am). Then, like in #1, a rise in ORP as chlorine is added to the pool. Overshoot is much lower in this instance, as the pool is occupied and mid-day sunshine contributes to rapid chlorine breakdown. | |||
