Can you put chlorine tablets in a well?

Never pool tablets: trichlor tablets carry cyanuric acid, which does not belong in drinking water. Calcium hypochlorite pellets made for wells are a different product; they sink and dose the bottom of the water column as part of a treatment, and they carry every limit chlorine has. Dropping tablets in as ongoing maintenance is not a strategy: it corrodes the pump and casing and never reaches the biofilm.

Any chlorine product for a well should be plain calcium hypochlorite or sodium hypochlorite labeled for potable water, dosed by your well's gallons rather than by the handful, held for the contact time, and flushed until a residual test reads zero.

If the goal is a better treatment, the chemistry matters more than the form factor: chlorine dioxide holds its strength at real well pH and strips biofilm per its manufacturer's published data, which is the treatment our kit ships, sized to your well record.
