As my tank is maturing so are my methods -- and I wanted to share the first of my side by side.
Like many out there, I started with the reasonably priced and easily available API Test Kits and have relied on them for the first months of my tanks existence with good results to date - fish alive, corals alive.
As I have added more corals I have noted a decline in measured Ca - as expected as some is now being consumed. I am using IO Reef Crystals and no additional Ca supplementation at this time. Historical Ca results have from 440 ppm on initial set-up to a more consistent 380-360 ppm over the past 60 days.
Tonight, Side by Side testing was conducted:
My tank says its 'ok' but its young and I have added a number of LPS and a few SPS over the past few weeks.
So, what say you R2R? User error with new RS test? Poor API - don't trust it? Keep an eye on it?
I will follow this up tomorrow with the KH and Mg results side by side to see what else I can.

- API Ca = 380 ppm
- RS, 1 = 460
- Rs, 2 = 440
