Unstabilized chlorine is chlorine that does not contain a stabilizer. It avoids any possible over-stabilization, disappears completely after a few days and does not saturate the pool water. It can be supplemented with stabilizer separately in order to dose it precisely.

It is possible to find it in two forms: solid calcium hypochlorite or liquid for dosing pump (sodium hypochlorite)
