So, I have both the High Range test provided with the Marine Care Multi-Test kit, and the Low Range via the Nitrate Pro test kit. The Nitrate Pro kit supposedly allows for High Range testing via dilution of the test sample. However, I am getting WILDLY different results between the two tests.
Steps High Range Specific Test:
5ml into vile, add 5 drops A, shake for 10 seconds, add 1 scoop B, shake 60 seconds, add one scoop C, shake 10 seconds, read 10 minutes later. Getting between 10 and 20ppm (which is where I want it really)
Steps Low Range used as High Range:
15ml RODI, 1ml sample, add 5 drops A, shake for 10 seconds, add 1 scoop B, shake 60 seconds, add one scoop C, shake 10 seconds, read 9 minutes later. Getting 4ppm (actually the color is BARELY registering, it's dang near clear with a twinge of pink to it).
Any thoughts on which one I should believe? I bought the Low Range (Pro) test kit because I suspected the Marine Care one was reading too high, but I didn't think it would be THAT far off... Really don't want to spend the money on a Hanna, but would like some feedback on the accuracy of either of these tests... Water testing is the most tedious part of this hobby, and I'm half tempted to cash in part of my 401K to get a reefbot, an IONDirector, or a Mastertronic, lol...
