The Salifert Phosphate (PO4) test kit is a highly professional and extremely accurate test designed to measure phosphate levels in both freshwater and marine (reef) aquariums. Phosphates are a critical parameter; elevated levels can lead to unsightly algae outbreaks and significantly inhibit the calcification and growth of hard corals.

This test kit is renowned for its high sensitivity, allowing aquarists to detect even the smallest trace amounts of phosphate before they become a problem.

• High Sensitivity: Detects very low concentrations of PO4, essential for reef aquarium success.
• Dual Application: Perfect for both saltwater and freshwater environments.
• Easy to Use: Comes with a clear and easy-to-read color comparison chart.
• Great Value: The kit is sufficient for approximately 60 individual tests.
