Chloramine - check your water source!

Ya, not a bad deal these strips. As you can see the one I have also does pH & alk. Don't recall if I tried one of these strips in my tank water. Might should do that some time & compare to the liquid test kit readings. According to their site, the strips may end up being more accurate due to less prone to errors as when counting drops of reagent with the liquid kits.
