Before balancing your swimming pool water, you will have to test it first. You should also test it frequently. Many factors contribute to the alteration of your pool water, such as weather and any chemical additions. Testing your pool water regularly will let you know exactly where you stand with your water...and help prevent possible future problems.
What chemical levels do I need to test for regularly?
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.
How often do I need to test the water?
Every day is optimal, but that might be a bit much for most people. Backyard pools should be checked for pH and chlorine levels at least 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 ten to fluctuate less, so weekly testing should be sufficient.
What are the recommended levels?
- pH: 7.2 - 7.8
- Chlorine: 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
