New RO/DI PH question


New member
I just got my RO/DI system up and running. I tested the PH and found it at 7.4. My question is: Is it better to add it to the tank (top off water only) and adjust the tank or try to adjust it in my RO storage container. When I perform a water change I'll adjust it in the salt barrel before I add to the tank.

your thoughts?

that is the normal pH level for rodi water, once you add it to the tank it will stablize and when you add your salt to the water it will also bring your pH to the correct level no need to try and adjust it.

The pH in your fresh top off water or the fresh RODI water you make up your salt mix in will have no effect on the pH of the saltwater you make from it.
