Bather load
The number of swimmers using a pool at a given time, one of the biggest short-term drivers of chlorine demand and water cloudiness.
Bather load refers to how many people are swimming, and for how long, which directly affects how hard a pool's sanitizer has to work. Each swimmer brings in sweat, sunscreen, body oils, and other organic material that consumes free chlorine and can push combined chlorine up quickly. A pool that holds steady chemistry all week can look and test very differently the morning after a pool party; a higher bather load calls for extra testing and, often, an extra dose of chlorine rather than assuming yesterday's numbers still hold.
