Ph Calibrating with the P3 upgrade

[marinfreak]

I am just about to upgrade my PII Ex to the PIII ex however as I know I will need to recalibrate the sensors, the question is for the PH for my reactor I only have PH 5 and Ph 7 solutions at the moment. Normally on the PII you need to use Ph 4 and Ph 7. My question is with the new software can I use PH 7 and PH5 solutions or do I need to wait until I can get some PH 4 solution.

Hi
Hope this helps you as i did a P2 plus to P3 upgrade shortwhile ago. I use ver 5.07 and fimrware 5.00k.
I virtually lookeed at most of the settings and recall seeing calibration options from PH4 to PH 10.
When i did the upgrade default was PH 4 and PH 7
I used PH7 and PH10 for my reef tank. ( i used PH 10 as ididn't have the ph 9 fluid)You can change the calibration setting within that range.
