The Red Sea Phosphate Pro Test Kit is a highly accurate colorimetric test designed for measuring ultra-low concentrations of phosphate in reef and marine aquariums. Phosphate levels directly impact coral growth, coloration, and algae development, making regular monitoring essential. With an accuracy of 0.02 ppm, this test kit is ideal for reef keepers who want precise control over nutrient levels to achieve a healthy, thriving reef ecosystem.
Ultra-Accurate Readings: Measures phosphate with a resolution of 0.02 ppm, suitable for low-nutrient reef systems.
Supports Coral Health & Coloration: Maintaining low phosphate promotes strong coral skeleton development and vibrant colors.
Reliable Color Comparison: Includes a clear comparator for easy and consistent results.
Long-Lasting Supply: Provides up to 100 tests per kit, ensuring extended use.
Part of Red Sea Reef Care Program: Integrates with other Red Sea test kits to maintain balanced nutrient and element levels.
Designed for marine and reef aquariums where phosphate control is critical.
Follow the step-by-step instructions for accurate colorimetric testing.
Recommended testing frequency: weekly or more often in systems prone to phosphate fluctuations.
Reagents for up to 100 phosphate tests.
Glass vials, color comparator, and accessories for accurate measurement.
For Reef Aquariums: Especially valuable in SPS-dominated tanks where corals are sensitive to phosphate.
Target Range: Maintain phosphate levels between 0.02 – 0.05 ppm for optimal coral growth and reduced nuisance algae.
Use with NO3 Pro Test: Pair with Red Sea’s Nitrate Pro Test Kit for complete nutrient management.
