API NITRITE TEST KIT 180-Test Freshwater and Saltwater Aquarium Test Kit

Makes having a tank a little easier

This arrived with nothing but the liquid, the vile and color chart were missing.

Excellent way and only good nitrate kit for the money....the should make a digital kit that, mesures everything. ?.wouldmt that be nice

Very easy to use, has easy to read directions and gives accurate readings

Works great. Lets you know an important monitor for your aquarium

Received quickly, but although the box appeared new, there was neither a test tube nor a color chart included. I can use other tubes, ok, but how to read the result with no color chart for comparison? Had to find a picture of it online. Clearly used, returned, and sent back out again, minus those key components.

very good product

I performed accurate calibration using distilled water and nitrite-ion calibration solution. Every time testing results were 2-4 times lower than expected. 0 and 0,1 values are not distinguishable at all. It is hard to match sulution and scale colors because scale has much more of red.

use it for my AP system

Great product
