When slamming the pool, how often should I add the amount of bleach that the pool math says to?

Test and adjust chlorine levels as frequently as practical, but not more than once per hour, and not less than twice a day. Chlorine additions should be frequent, especially at the beginning. Algae and other organic debris will consume chlorine very rapidly at first. As things progress, you will lose less chlorine each cycle and can add chlorine less frequently.

Agree and really, it's hard to say. If you're losing 5ppm FC an hour after SLAM'ing then you need to add more. If you're losing 2ppm FC in 6 hours, then redose accordingly. Each pool is individual. Not any 2 pools are the same so do for it as it needs by using the test kit.
