Funny I was just testing my Calcium a few minutes ago with a Hanna checker. It read 551. Fail haha! Last reading was 490 and I haven't done any water changes or added calcium.

IMO the power packet is dumb and a mess. Also adding droplets is way easier and very accurate compared to syringes. They did get the reader right however they have a long way to go on everything else.
