Reefkeeper lite pH probe question

[PR_Reefers]

When I test my kalk's pH with my reefkeeper pH probe it clims and then reads error!!!:squigglemouth: has this happened to anyone... is this normal? I calibrated it according to instructions and it read 4.03 in the pH 4 solution and 10.04 in the pH 10 soluntion... should I be concered the unit is not functioning properly? thanks for your help

The stock pH probe may not be made to read high range pH? I would do a search in the digital aquatics forum. I'm sure you can find someone who had similar problems. Just out of curiosity, why are you trying to measure the pH of your kalk?

for nothing really... I just tried it out of curiosity... to see how high it's pH really was!!:smile:

Two things here:

1) The ph probe maxes out around 10 (i beleive)
2) Kalk pH is around 13...or 13.4...something like that.

... makes sense...:smile: I knew kalk had 12+ pH, but didn't know if the RKL had a max limit!
