The numbers that keep water clear.
Test first, balance next, sanitize last. Plain-English ranges and fixes — not a store aisle.
A simple order that prevents chemical ping-pong
Fix one layer at a time. Retest before the next move.

Chemistry is the numbers. If you need a different job, go there directly.
- Water looks wrong (green, cloudy, smell) Symptom-first fixes — not more numbers first.
- I need a weekly rhythm, not a formula First-year map and care programs.
- How much chemical should I add? Dose calculator — estimate, then retest.
- Which test strips or shock should I buy? How to choose gear — not a fake top-ten list.
