All Seas Marine Salifert Nitrate (NO3) Test Kit is a liquid saltwater aquarium test for measuring nitrate, with 50 tests and detection down to 0.2 ppm.

• 50 tests per kit — measure nitrate across multiple aquarium checks.
• Detects nitrate levels as low as 0.2 ppm — supports monitoring at low readings.
• Dual-range testing — made for reef and fish-only aquariums.
• No amine interference — helps provide quick, reliable nitrate-nitrogen measurements.
• Saltwater aquarium use only — suited to marine aquarium water.

Whether you maintain a sensitive reef aquarium or a fish-only saltwater setup, nitrate testing gives you a specific reading to use when monitoring aquarium water. This liquid test kit is intended for both experienced reef aquarists and people new to the saltwater hobby, with a dual-range format for two common marine aquarium types.

What nitrate levels can this test detect?

The Salifert kit detects aquarium nitrate levels down to 0.2 ppm. Its dual-range design serves reef aquariums as well as fish-only aquariums, so it can be used across these two saltwater setups. The test measures nitrate-nitrogen, and the absence of amine interference supports quick, reliable readings.

• Measurement focus: nitrate-nitrogen.
• Lowest stated detection level: 0.2 ppm.
• Test format: liquid.

Is this kit suitable for reef and fish-only aquariums?

Yes, the Salifert Nitrate (NO3) Test Kit is a dual-range test for reef and fish-only saltwater aquariums. Reef keepers can use it for nitrate monitoring in sensitive reef aquariums, while fish-only aquarium owners can use the same kit for their marine setup. It is for saltwater aquarium use only, so its stated scope does not include freshwater aquariums.

• Suitable aquarium types: reef and fish-only.
• Intended water type: saltwater.

How many tests are included, and who can use the kit?

Each Salifert kit provides 50 nitrate tests and is designed for adult aquarium hobbyists, from beginners to experienced reef keepers. Its liquid format is presented as easy to use, making it a practical option for routine nitrate checks in a saltwater aquarium. The supplied information identifies the test count and format but does not give a step-by-step procedure, so use the kit's own instructions when carrying out a test.

• Quantity: 50 tests.
• Age range: adult.

This kit suits adult saltwater aquarists who want to monitor nitrate in a reef or fish-only aquarium, including reef keepers looking for readings at low levels. It combines a 0.2 ppm detection level with 50 liquid tests for marine aquarium use.
