Frequently Asked Questions
Q: Why should I test for phosphates?
A: Phosphates do not directly make pool water unsafe, but elevated levels can encourage algae growth when other water conditions allow it. Regular testing helps you identify buildup early and determine whether a phosphate remover is needed.
Q: Where do phosphates come from?
A: Phosphates can enter pool water through rain, soil, garden runoff, leaves, fertilisers, and some cleaning products. Testing is particularly useful after heavy rain or when algae repeatedly returns after treatment.
Q: How often should I test for phosphates?
A: Test as part of your routine water care, or any time algae is persistent, the pool has received heavy rain or garden runoff, or you are preparing to use a phosphate remover.
Q: Do these test anything other than phosphates?
A: These strips test phosphate only and do not replace regular testing of chlorine, pH, total alkalinity, or other essential water-balance parameters. Pair with our 5-in-1 Test Strips for a full water chemistry check.
Q: How do I store the strips?
A: Keep the container tightly closed in a cool, dry place away from direct sunlight and moisture. Do not use wet fingers to remove strips.
