Salifert Nitrate ProfiTest kit

The Salifert Nitrate ProfiTest Kit is a professional-grade water test for marine and reef aquariums where accurate nitrate monitoring is critical. Many commercial nitrate test kits suffer from amine interference — a reaction that causes measured nitrate to read significantly lower than actual levels, providing a false sense of water quality. The Salifert Nitrate ProfiTest is formulated to eliminate amine interference entirely, delivering results that accurately reflect true nitrate concentration.

Nitrate accumulates when denitrification is incomplete or when biological loading exceeds the system's capacity through overstocking, overfeeding, or insufficient anaerobic zones. Elevated nitrate drives unwanted algae proliferation and inhibits coral growth. In reef aquariums, nitrate concentration should ideally remain below 1 mg/L; fish-only systems typically tolerate higher levels.

Key Features

• No amine interference: Returns accurate results where standard test kits commonly under-read.

• Fast results: Full test completed in under 3 minutes.

• Wide measurement range: 0.2–100 mg/L total nitrate — covers reef-low and fish-only-high scenarios.

• 50 tests per kit.

• Suitable for: Reef aquariums, marine fish-only systems, and aquariums housing sensitive invertebrates.
