KH director and power outage

wmb0003 · May 20, 2022

I had a short power outage last night, shortly after midnight. I have my KHD perform a test at midnight so it was mid test when the power went out. It tested again at 4am and it showed a very low dKH(~4dKH). So when I woke up, I pressed the empty measurement cell button. Was going to wait and see what the 8am test showed, and now it shows 11.9 dKH. Normally my tank runs at ~8dKH +/- 0.5.

Does anyone have experience with this situation? Is there anything else I should try before I recalibrate all dosing heads and recalibrate pH probe?

Good Morning,

Before doing the calibration I would run another manual test to see if it comes down, before recalibrating everything.

So I realized I pressed the wrong button this morning, I should have pressed flush measurement cell instead of empty. I flushed it and ran 2 more tests and both readings are in the correct range.
