I have read past posts, but couldn't find what I was looking for.

Does anyone know for sure if it is harmful or not to put chlorine pucks in the skimmer?

Some say the acid build up can hurt the pool equipment when the pump is turned on after being idle for a period of time, but just how much harm can be done for the few seconds the pH levels are very low? Doesn't the water in the pool equipment very quickly (seconds) return to the pool's pH level?

Thanks, David
