Test kits

[kaileykari]

I am using Nutafin test kit. It was the only test kit at my LFS. I have a bit of trouble reading the results, hard to tell which color it is. Is there a recommended test kit that is easier to read? I have a 20 gallon, and I want to be accurate. Thanks!

I meant Nutrafin!

I recommend either Salifert or Elos. They cost considerably more than a Nutrafin or AP test kit, but they are way more accurate and easy to read.
