Q: What chemical levels do I need to test for regularly?

A: The four main tests to perform with a test kit are, pH, chlorine (or other sanitizer residual), total alkalinity and calcium hardness. Cyanuric Acid Levels, Mineral Content, Total Dissolved Solids, and Acid or Base Demand tests may also be performed as needed.


Q: How often do I need to test the water?

A: Ideally everyday but that is a bit much for most people. Commercial pools are required to check chlorine levels every hour and record their findings in a log, however the backyard lifeguards should check their chlorine and pH levels 2-3 times a week. Chlorine should be fed continuously through a feeder device to maintain a consistent level. Total Alkalinity and Calcium Hardness levels tend to fluctuate less, so weekly testing should be OK.

Q: What are the recommended chemical levels?



7.2 - 7.8


1.0-2.0 ppm

Total Alkalinity

80-120 PPM

Calcium Hardness

180-220 PPM, though some say 200-400

Cyanuric Acid

25-50 PPM

Total Dissolved Solids

500-5000 PPM
