Sera Mg Test Kits ???

[neelix]

Figured I would post here for visibility.

I ordered a Sera Mag test kit, but received the refill instead. Does anyone here use this kit? I don't have instructions so was hoping this is just a color shift test kit?? If so how many ml of water do you start with and how much does each drop stand for? Any help will be rewarded with good karma:)

Thanks

Rob
