PH and RO/DI
Does RD/DI water can be at 7.5 of PH? is this an indication of bad water Quality?

DI water does not contain enough ions to give an accurate pH reading.

i dont get your answer AZ....lets say my freshwater tank is at 7.0 ph. I want to make sure I dont ph shock the fish when I change the water. how do I know the ph of the rodi water if it cant be accurately measured?

So if my RO/DI is reading 7.5 of PH this indicates bad water quality?
Sorry I just want to be sure. Thanks.

Pure RO/DI in a vacuum is hypothetically at a pH of 7 . Because it has so few ions, as AZDesertRat pointed out, any minor contamination will affect the pH test and make it meaningless.
A better test would be for Total Dissolved Solids (TDS). Water from an RO/DI should have a TDS of close to zero ppm.
