Hagen test kits tend to be regarded as . . . um . . . shall I say unreliable. While it's difficult to screw up a pH test kit, Hagen is capable of anything they set their minds to. Irregularities in storage prior to and after purchase can have a serious affect on the accuracy of a reagent dependent test kit. Bottom line: before you go chasing numbers, make sure that you really need to in the first place.
