I've used a regular pH meter and then bought a fancy/better one -- the Apera
I used the controls and I keep the Apera in the recommended storage solution.
When I initially place the probe in the water, the pH comes out at around 7.35
However, if I let it stay in there, it keeps rising, starting from 7.35 and going all the way up to 7.8 over a period of about 5-7 minutes
This probe is brand new and only been used like 5 or 6 times and I already did the recommended prep/control procedures.
What's going on with the pH fluctuating constantly?
