sera Nitrate-Test (No3) 15 Ml, 0.5 fl.oz Aquarium Test Kits

Accurate test kit, but it has quite a few steps to complete.

Can detect at high ranges but only at very wide intervals. Any results below 10 ppm NO3 all look the same to my eye (sample measuring 5 ppm on a different test comes back zero on this, based on my subjective interpretation of the color charts). For high range, OK; for low range unusable.

Ease of use: no ideaQuality: no ideaAccuracy: no ideaPerformance: no ideaWho knows if it works or not. Instructions say to use spoon (red) to measure some of the elements.There is no spoon.It doesn’t even say how much said spoon would hold.Without accurate measurements it’s useless.Returning for refund.Disappointed.

What I did not like:1 - more bottles are needed to compared to API's nitrate test.2 - unscrewing the caps each time is unnecessarily difficult. .3 - I'm hating the microscopic spoon. More opportunity for waste and inexact measurement4 - only 1 vial in the kit. I'm running nitrate tests for 4 different tanks. It quadruples the time needed if I have only 1 vial.

Tests about 50% lower than api and Salifert do not buy unless you want to think your tank is clean when it isnt

Couldnt use this test. It arrived without the "measure spoon" needed in the instructions and there is no indication of how much reagent to use other than "measure spoon"....and this garbage kit cost me 17$????......horrible.

A pesar de tener que usar 4 reactivos la prueba se hace rápido porque no hay que mezclar eternamente como con otros test. La lectura es fácil de hacer porque los colores de la escala son muy diferentes, pero esto también es un problema porque la diferencia de valores entre cada color es muy grande (0, 10, 25, 50 y 100 ppm).Para mediciones durante el ciclado funciona muy bien porque aquí se producen valores muy altos de nitrato, pero en el uso cotidiano no es práctico porque no quieres mantener valores por encima de 10 ppm, hay otros test que permiten medir valores menores.
