I wonder if anyone has tired Hanna's Marine Ammonia checker and if they have confirmed it works properly.
I have had good experience with most of their egg shaped "checkers", yes even the Calcium Checker, but the last one (HI783 - Marine Magnesium Checker) was a disaster.
They were supposed to send new reagents if you registered to their website but so far the only response I saw was a notification of price increases :S
Anyway, I'm considering getting their Marine Ammonia checker to do some experiments with copepod culturing but I wonder if it provides reasonably precise measurements.
Any feedback will be greatly appreciated.
