But that is negated by proper, regular testing and by adjusting your chlorination method appropriately.

Seriously, the only WRONG way to chlorinate is without testing or compensating when the test results tell you to.

(....OK, ok, and mixing chlorine types in the same container, like the skimmer or automatic chlorinator--but that's just plain dangerous and stupid... )
