Has anyone used this. Nice and simple to use, however seems to give very different results to my drop tests ( which are many years old and been unused for years-do they go out of date?).
My aquarium has only been running a few weeks and my drop tests show Nitrite somewhere a tad darker than 0.3, whereas the JBL proscan dip test show zero- which is slightly concerning?
Consecutive test showed wildly differing GH levels.
