Apex pH Probe

Did you get this sorted out? I dropped mine in today and got the same reading but my API test has consistently read 8.3? I don't have any calibration fluid ATM.

I'm waiting for pH10 calibration fluid in the mail.

I'm recording the Apex results as my pH, but I'm backing it up with my API test. My API test tends to show my pH a little higher than the Apex probe.

The probe records between 8.11 and 8.23. It took a little bit (couple of hours) for it to settle in. That first reading may have been erroneous.

I'm pretty confident in it. If it is out, it isn't out by much.

Adding water to a vial to test with a test kit will alter the pH slightly up. So it will read at least a bit high.
Testing pH will also make a person crazy, I highly recommend against it. My Apex pH probe is still in the box, right where it belongs

pH doesn't make me crazy. Ca/Alk/Mag do!

I don't test that either, not taking any chances!

I agree with Brad on this, ph probe will drive you crazy one day. I just don't bother calibrate or care about my ph probe reading any more.

Sounds like a plan.

I sleep much better when I'm not chasing numbers. I tested Ca once this year, it was good. Alk was a bit high, figured if I left it alone, it would probably level out. Corals look good, I was probably right.

Alright, will check mine again in the morning. Ty!
