So I've been dripping a Kalk slurry for about 36-48 hours now and have been keeping a close eye on my pH. I took out a probe I hadn't used in a while (stored in potassium chloride), calibrated it using 10 and 7 standards, and watched.
My daily pH range has been roughly 7.75 - 8.1. I just don't believe that. I am running my skimmer line outside, I keep my alkalinity around 11-12, and as mentioned am dripping a kalk slurry.
I ran a red sea color pH test this morning and came back at 8.2.
So, my question is, if the probe is calibrated at 7 and 10 standards why would it read 7.75 directly after calibration? Temperature differences are about 10 degrees F so some error there but this much?
Thanks
