Such as the sharing of chemicals in a work pool?

I've read that online balance the pH, you need to distribute chemicals, and you need chemicals to bundle adjustment of the alkalinity. How can we approach the effect of pH alkalinity? I understand how to add chemicals. I want to know why the combination of chemicals affects the alkalinity more than pH, and the distribution of the chemical in a distributed Villa has more influence on the pH balance.

I am a pool owner, but do not know what .. To me, everything goes into the skimmer and never a problem.I that my chemical products distributed in a more concentrated area ….. So I'm looking forward to someone else noticed
