Tetra 19540 First Impressions
Two packages were inside.
This is essential for an accurate reading. No one brand is going to guarantee against this. A brand new aquarium will experience what is called a cycle. Strips were always stored in a sealed dry place. I have a 55 gallon tank with a few large goldfish. Some of the readings develop better than others. I have not found that to be true for myself.

Tetra 19540 Final Thoughts
Very easy to use.
If your lighting isn't right the colors will be very off. So this thing worked very well and gave a reading that made perfect sense. My water was good to go and soon after I for fish that are doing well! The test strips work as advertised. I set up a bunch of 20 gallon tanks for fry and stuff.
