The LAMOTTE 3040-g-6 Insta-Test High Range Pro Phosphate Test Strips provide fast, accurate phosphate level readings for pool water management. Sold as a case of 6 bottles, these dip-and-read strips are designed to detect elevated phosphate concentrations that standard low-range strips cannot reliably measure. High phosphate levels accelerate algae growth and degrade water quality, making routine testing a critical step in any pool maintenance program. Pool service professionals and water treatment technicians use these strips as a front-line diagnostic tool before applying phosphate remover treatments.
These strips are suited for both residential and commercial pool applications where phosphate levels are expected to be elevated — commonly seen in pools fed by well water, subject to heavy bather load, or located near agricultural runoff areas. The high-range format makes them appropriate for initial shock-level testing as well as ongoing monitoring after phosphate treatment. Each bottle contains enough strips for multiple test cycles, supporting regular service routes without frequent reordering.
Designed for use in residential and commercial pool water testing applications where high-range phosphate measurement is required.
Pool water testing requires no tools and no power shutdown. Follow the strip manufacturer's dip time and color-match instructions precisely — results read too early or too late can produce inaccurate readings. Collect water samples from elbow depth away from return jets to obtain a representative reading. Dispose of used strips per local regulations and store unused strips in a sealed bottle away from heat, humidity, and direct sunlight.
