I have bought several tests, replacement tests, and obviously the TFP test kit...all through TFP. I now have 5 test tubes with ml measurements on the side. Of the 5, 3 are equal measurements when I fill it with 25ml. The 25ml poured into the other 2 tubes are closer to 30ml.
1. Am I crazy?
2. What tubes do I use??? How screwed up have my tests been for the last 2 years?
3. Shouldn't all the test tubes be labeled accurately?
3. Kinda feeling crazy!
