I have a Seneye that I initially trimmed to match my Salifert PH test. Anyhow now my Seneye is reading 8.3 whereas my Salifert is reading at 8.5. Would you trust the Seneye over the Salifert test or should I retrim the Seneye again?
I'm not sure honestly. I soaked the new slide for 24 hours as suggested and it's been in the tank for about 16 days now.
I've found the PH trend on the seneye is accurate. It's harder to match a test vial to a colour chart. Having said that, you can retrim the seneye if you think your judgement of the colour chart is solid.
I'm going to un-trim the seneye and test with the salifert. Do you have any idea as to why the seneye would read lower than the salifert test?
No, but mine always did too and once trimmed stayed true with my salifert. I use an apex now, I thought replacing the slides all the time was a bit silly. I'm not sure if it matters for PH, but did you make sure the 'reef tank' setting is checked off in the seneye software?
As for your image, would need to see the vial above the white part not the coloured part to make a comparison.
Here is an updated image of the vial. I had originally had it in the white area next to the colors.
ETA: The two tests are more than an hour difference on when I took the test.
