Water Balance Checklist
A water balance checklist is a sequential list of tests and adjustments that ensures all pool chemistry parameters are brought into range in the correct order.
Definition
A water balance checklist is a sequential list of tests and adjustments that ensures all pool chemistry parameters are brought into range in the correct order.
Typical Values: TA → pH → CH → FC/CYA (this order)
In Plain Language
A water balance checklist typically covers: 1) Test all parameters. 2) Adjust total alkalinity to 80–120 ppm. 3) Test again and adjust pH to 7.2–7.6. 4) Adjust calcium hardness to range. 5) Adjust chlorine and CYA to target. 6) Calculate and check LSI. 7) Document all tests and additions. Following the checklist prevents the common mistake of adding multiple chemicals simultaneously or in the wrong order.
Why It Matters
A written checklist ensures nothing is missed and that adjustments are made in the correct sequence.
Typical Values
