The Insta-Test Phosphate pool and spa strips provide very quick and reliable water test results. Phosphates are important contributors to algae growth and can reduce the effectiveness of some automated chlorinated systems. This unique test allows the user to read low range test results by looking down in the reacted sample tube. Test instructions are on the bottle along with a color chart.
