Ro water

[courtstig]

My ro water in my topoff chamber in my sump drops in ph is this normal?

 

[X-37B]

Ph of my ro/di is around 7.

I would think that as it absorbs co2 from the room air that would cause a drop in pH

Normal. It has no buffering ability so it’s pH changes very easily.

It’ll go up when added to the tank as it will be aerated.
