Non-chlorine shock or chlorine shock?

Two shock products with different jobs: MPS for routine weekly oxidising, calcium hypochlorite for bringing neglected water back.

What matters	Non-chlorine shock (MPS)	Chlorine shock (calcium hypochlorite)
Typical use	Routine weekly oxidising after ordinary bathing loads	Resetting water that has turned cloudy or green
Mode of action	Oxidises organic bather waste, leaving the sanitiser free to disinfect	Lifts free chlorine to a high level that destroys bacteria and algae directly
Effect on the sanitiser residual	Chlorine-free; in bromine systems it regenerates bromide back into active bromine	Adds a heavy chlorine dose above the normal maintained level
Wait before bathing	Brief: circulate, retest, then bathe	Until free chlorine has dropped below 5 ppm
Frequency	Every week, plus after parties or heavy use	Only when the water needs recovering
Cost per treatment	Small regular dose, low cost	Larger dose, but needed far less often
