I appreciate the reply. You are exactly right if I trusted one, why shouldn’t I trust it now? I over think a lot and was just seeing if anyone had other test that they preferred for this purpose.
I just tested everything again and the only thing that seems off is alk… Hanna tested 10.7, 10.8 and trident was reading 10.47… MG, CA(via salifert)seem to be right on. i’m switching to ABC reagents after this two month pack is up. I might as well start tank calibrating and not trusting the solution now.
For me the benefit of using my test kits and tank water to calibrate is that I can always expect trident results to match a manual test. So what if my manual test is not exactly accurate. I wanted a seamless transition to trident and stability is more important to me than whether my tank is truly running at 9.8 dkh instead of 9.5 dkh. My trident and my test kits both read 9.5, and I keep it stable. If I used the trident calibration solution, maybe it tells me my tank is at 9.8 dkh. Ok, then what? Do I reduce alkalinity to get back to 9.5 which would then show up as 9.2 on my manual kit? Keep it at 9.8 on the trident and try to remember that my manual test is going to read 0.3 dkh low? Or, calibrate with tank water and know that my manual test results should always match the trident results? To me the answer was obvious…I am not sure what the trust issue is. Are you expecting the Trident and manual test results to match or are you questioning the calibration solution by Neptune? What leads you to believe there is something untrustworthy and what data do you have out of curiosity?
There was a interesting thread on another platform last year and somewhere in the thread I replied that I thought the supplied calibration bottle was amazing. A fellow hobbyist rightly called me out to define my choice of wording which I thought was fair. I should have said in my opinion or in my experience and then provide why. In this case it was me running a couple tests using both Neptune's calibration solution and Fauna Marin's multi reference with the reagent bottles under 30% remaining.
This assumes of course that A Fauna Marin's reference solution is valid and B Neptunes calibration solution is valid. In both cases I am trusting them at their word and label. Results below. For a hobby grade test kit and knowing how Jim has done a few spot checks on Neptune's calibration solution, I figured it was good for me.
As far as non OEM reagents go I am of no opinion as I've not used them. Hope your day is well.
