APEX PH calibration question

[snowmansnow]

ok, i understand the process, but i'm all out of 7. solution... any chance I can use 4 and 10 ? or will i have to wait on 7 to ship ?

Your really need the 7. solution to calibrate the Apex and should wait till it comes in. If you were close I could have given you some.

Use the 4 and 7 to do the probe being used in a Ca Reactor and use the 7 and 10 for your tank probe.
