Hi! I’m wondering what others think about this…
I’ve been working on lowering nitrates for the past few months. Initially I was using the API test, which has been reading strikingly high: never under 30 ppm, often 40 or 50+
So I bought a Salifert kit and that tends to show somewhere in the 25 - 30 range consistently.
I also test w/the new Hanna HR Nitrate checker and that one is consistently telling me my nitrates are between 10 and 20 ppm. Usually somewhere around 12.
So I guess my Q is: What are opinions on which test to trust? I’m carbon dosing to lower nitrates, and back to doing weekly water changes, but I don’t want to be overly aggressive if, say, the Hanna one is most likely correct.
