Hi George,
You only need to calibrate at the 7.0 position because aquariums operate in the netural zone of the pH scale. You should calibrate your probe at least once a month. You can purchase on line from the US distributors but they only sell units with 110v plugs so if you are outside the US then get a unit that matches the power supply for your area.
Best regards
