I really need to find the holy grail of pH info, I know it's suppose to be a measurement of hydrogen ions/ acidity or basicity, But in my mind, the pH shift there is nothing but less CO2/more O2, so I don't understand most of the cases where pH swings are said to be dangerous, or why some people go to great lengths to monkey with their pH for a certain fish species just because some profile said they require a certain range, how can they know the CO2/O2 relationship of that fish's natural environment and how it relates to an aquarium? If there's some other relevant change happening there that constitutes danger to the fish then I missed it, maybe I just don't understand pH well enough. Seems like they should be able to handle gas off. This is a big reason why I rarely use my pH reagents anymore, like when acclimating I just ignore it and make sure temp, KH and GH are in check, and SG for SW inverts. Like when I reconstitute RO, I can add the same amount of KG/GH as the tank but the pH is 7.2 where my tank is 6.6, from the bucket being sloshed around and no CO2 injection as the tank has. If that pH shift can hurt my fish, someone please enlighten me.
