API Nitrate Test Kit NO3

Looking at colour chart for reading. Looks like it will be a bit of a guess, colours of widely different readings very close.

the kit is easily to use and you get a decent amount of tests for the price.

Great service, great product, and fast delivery.

The API Nitrate Test is similar to others on the market. It is reliable, if the somewhat complex directions are followed. It is VERY difficult to distinguish colour variation between 10 and 20 pmm.

I have purchased a few times from the Tech Den. Excellent, speedy service each time. Staff extremely knowledgeable regarding their products as I have also called on a few occasions seeking advice. Cant comment re the mentos; my son gets them before me :) thanks for everything !

Great price, always a must with fish keeping This test kit can indicate how much water to change and if you are about to have problems

A well-priced, easy to use API test kit. Delivered quickly and long expiry date- the latter useful for a kit which will be used periodically on a cycled tank.

Easy, fast and convenient test kit.
