Yes.
No. It starts clearly enough for someone who has just bought a house with a pool, while giving established pool owners a repeatable testing, source-water and seasonal system.
The method focuses on the water chemistry every pool owner needs to understand. It is not an equipment manual for a particular chlorinator, pump, filter or automation system.
It replaces guesswork and routine dependence on pool-store advice. It does not replace a professional inspection of damaged, unsafe or incorrectly installed equipment.
No. Keep Your Pool Clean. The Four Numbers That Decide Whether Your Water Works, and the Order to Fix Them In is a digital book (a PDF).
