Seachem MultiTest Nitrite & Nitrate Test Kit

Nitrite is toxic and should be undetectable in any well established aquarium. During cycling, it may exceed 20 mg/L. Nitrate is relatively non-toxic, but it is advantageous to control it to under 20 mg/L.

MultiTest Nitrite/Nitrate measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 mg/L in marine or freshwater. The values reported by this kit are expressed as nitrite and nitrate rather than nitrogen (to convert to nitrogen, simply divide by 3.3 and 4.4, respectively). It performs over 75 tests and contains a reference sample for validation.


  • Measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 mg/L
  • Multi-cavity plate for simultaneous testing of up to 6 tests at the same time
  • Includes reference for test validation
  • Marine or freshwater

Eva C. ★★★★★

Finally a test kit that separates nitrite and nitrate clearly, instead of lumping them together. The color chart is easy to read even under my LED lights. My tank cycled in about three weeks with consistent readings.

Christopher ★★★★★

I've been using this during my fishless cycle and the clear color charts make it easy to distinguish between 0 and 5 ppm nitrite. It's nice having both tests in one kit.

Daniel E. ★★★★★

Finally, a test that gives me both nitrite and nitrate levels without needing separate kits. The dual-range titration is really precise, so I can track my cycling progress with confidence. My readings have been spot-on compared to my LFS’s results.
