Hi
I've been using an Alkatronic to monitor my tank's alkalinity for 2 months now.
Generally, it worked really well.
For example, it showed significant changes in alkalinity over a 24 hour period, which I was able to correct by dosing at specific times.
And while it's readings did not match my Salifert tests, which is very reliable, they were within 0.3 DKH of each other, which I considered acceptable.
However, I had not done a Salifert test for over a week and when I did i discovered the DKH readings from the Alkatronic was reading over 2 DKH higher than the Salifert.
I have no explanation for the sudden divergence. Any ideas?
I tried using the "baseline calibration" feature in the Alkatronic, which I assumed, perhaps incorrectly, was a way of adjusting the Alkatronic reading to a third part result.
So I divided my Salifert result by the Alkatronic result and a decimal figure shows up in the app, which presumably is the correction factor that the Alkatronic uses to modify its result to correspond to my Salifert result.
The first time I tried it, it seemed to work but shortly thereafter the Alkatronic reverted to the high readings.
I also noticed that when I tried to redo the calibration it doesn't work.
The decimal adjustment number shows up (I save it in the app) but when I exit the screen and then go back, I no longer see the decimal. Furthermore, the baseline calibration field is grayed out and says NA- presumably not available. I've tried redoing the calculation numerous times but it fails every time.
I have sent a similar message to Focustronic and am awaiting their reply, but I was wondering if anyone else can shed some light on this.
Thanks
