My pH was reading 8.25. I haven’t calibrated it in a while.
I calibrated it with a Milwaukee 7 and 10 solution, and my aquarium pH reads 7.8.
I calibrated it again with another set of Milwaukee, and the pH also reads 7.8
I then purchased Pinpoint pH solutions from Amazon and calibrated it a 3rd time, and it still read 7.8.
I was pretty thorough with the calibration process:
Rinsed probe with RO/DI and shook off excess water
Placed pH probe packets in tank water to get a temp of 77F
Placed probe in 7pH buffer solution.
Rinsed in a new cup of RO/DI water.
Shook, then placed in pH 10
Then I double checked both packets to see if they matched. The 10 pH matched perfectly, but the 7 pH showed about 6.8 (I rinsed in RO/DI before placing in the 7 to double check.
I took a cup of tank water (8dKH) and aerated it with an airstone outdoors for 1 hour.
The pH rose from 7.8 to 8.0
Does this seem correct? I don’t know. I’m still skeptical about my pH being this low lol.
