API freshwater master test kit is about the best around. Discounted down to 23.39 on Amazon at the moment.

I've gotta agree with the previous post. The API kit is the best.

API is ok for most tests. But for testing nitrates, I use Seachem nitrate test kit. It is so much easier and quicker than the API test for nitrates.

The API nitrate tester has 2 bottles. The instructions say to shake bottle #2 before use, and to shake the tube after the drops are added before starting the timer. This shaking is important as one of the reagents in bottle #2 settles on the bottom of the bottle and the shaking is to redistribute it throughout the liquid. I understand that some other makes also require one bottle to be shaken before use.
Failure to shake gives false readings. It is generally recommended that a new bottle or one that hasn't been used for a while should be tapped on the worktop first to break up any solid lumps. And shaking the bottle should be longer than the instructions say.
