API or Nutrafin GH/KH test kit??
I'd like to get a reliable GH/KH test kit, I was looking at the Nutrafin or API (both at LFS). The API had good & bad reviews, the Nutrafin I couldn't really find any reviews on.
Some people say the API is fine, others complain about the testing method (there is no color chart, water goes off scale, etc.). I have the API master kit and love it, but not sure about the GH/KH after reading some reviews.
Anyone have experience with either kit?
