Phosphate Test Strips 25 Strips | FreshWater

Check phosphate levels in your hot tub or spa with FreshWater Phosphate Test Strips. This pack contains 25 strips with a low-range scale of 0–2,500 ppb, giving you a dedicated test for phosphates as part of your water-care routine.

The bottle’s colour reference chart lets you compare your test result with the marked phosphate levels. Use these strips alongside your other water tests, including sanitizer, pH and salt testing where applicable. A phosphate reading does not replace those separate checks.
