Pros and cons of trial-and-error and predictive chlorination practices
| Chlorination practice . | Pros . | Cons . |
|---|---|---|
| Manual, dynamic feed on experience | Less costly | For small pools only; difficult to maintain residual chlorine |
| Automatic, dynamic feed on ORP controller | Less manpower | May fail to maintain residual chlorine at all times |
| Automatic, dynamic feed on timer | Less manpower | May fail to maintain residual chlorine at all times |
| Predictive, dynamic feed on chlorine demand | For both small and large pools; easy to maintain residual chlorine | Requires projections on the daily number of bathers and use of a sound chlorine consumption per capita coefficient |
