FreshWater Phosphate Test Strips (6-Pack)

FreshWater Phosphate Test Strips provide quick and reliable water test results. Phosphates are contributors to algae growth and can reduce the effectiveness of some automated chlorination systems.

This test allows you to read low-range test results by looking down into the reacted sample tube. Test instructions are on the bottle, along with a color chart. Keep phosphates below 300 ppb to avoid problems in your spa.

This unique bottle has a molded desiccant liner that protects the strips from moisture intrusion. It is important to keep moisture away from unused strips so they can provide an accurate test to help protect bathers and spa equipment.
