Pinpoint Calcium Monitor

[Macropora]

Anyone use the Pinpoint Calcium Monitor? How accurate is it compared to a test kit (eg. Salifert, Elos, etc...) and how often do you need to recalibrate it? Any feedback would be appreciated. :tongue1:

Accurate but you need to calibrate very often.

Accurate but you need to calibrate very often.

Would you say once a week, every 2 weeks, once a month?

I would recalibrate it every week
