I just got the Reefbot today. The first thing that I will do is watch the youtube video on how to set it up and calibrate it. After that, where should I get the best reagents to do the test? I have heard that the API test kits are not too expensive but from reading the reviews, they are quite inaccurate. For those who just got this "expensive" device, where do you buy your reagents and which one do you use? This is like buying a printer, it is the ink/toner (and in the case of reef keeping they are the reagents) that is most costly.
