Superchlorination,
the addition of large amounts of chlorine, has some
drawbacks. Because it requires large amounts of chlorine,
it can damage liners and swimsuits and upset water
balance. Additionally, it is difficult to determine
proper dosage amounts and it requires swimmers to
wait until the level of chlorine drops, often a day
or more, until they can swim.
Non-chlorine
shock, on the other hand, does not require excessive
chlorine use and allows swimming almost immediately
after application, does not harm liners, has easily
determined dosage rates and does not upset water balance.
