Hi, I have a trick question here.
If we use DOS to do automatic water changes, and simultaneously we add NEW water and take out OLD water with the return pump on it did not mix the waters ?
I don't know if I was clear enough. But like, even if I take water close to my overflow and add new water in the return pump, the waters will mix. Right?
