I've been having issues with pH, I actually bought 2 probes - cheap ones, I calibrated using the 2 point method, and after a few days it would have a sudden drop and get out of range. Not sure if it is a setup issue or a probe issue.
I tried with both probes and they both did the same thing with a sudden drop. Any suggestions on how to fix it or a good pH probe?
