If you are getting a high PH reading from your ro/di unit you need to do a TDS reading, An ro/di unit that is working properly will generally have a low ph reading because the ro process removes the buffers.
Test your ro/di water after it has set with airation for 24 hours, if the ph is high test TDS.

The pH of RO/DI water is generally low (in terms of comparing to reef tanks), as stated by Shaun. What level are you getting, and how are you testing it?
