I wouldn't bother playing with it. Ph7.5 is just fine. Mine are in aPh 8.2 right now. Stability is better IMO

pure water is notoriously hard to get an accurate ph reading on

Hi rex82
I dont keep freshwater fish , i keep marines but when i buy my RO water i try and get it below TDS reading of 8ppm or less as my tap water has a TDS reading 27ppm. See if you can get it lower than 10ppm
As for the P.H i am unsure, i would have thought it would be 7.0
Cheers Tommo

7.5 - 8.2 is a perfect range dont modify it.
