Hi
I'd like to ask if its an golden rule to first calibrate at 4.01ph and then 7.01?
My profilux ask for 4ph water first when i calibrate my electrode. But i read somewhere that if calibrating with 4+7water always do 7 then 4. If calibrating with 7+10 water do 7 then 10.
Reason I ask, my tank operate at 6.70ph and calibrating with 7.01 first will give a more acurate pH value?
Thanks
Regards Rasmus
