I’ve have been trying to lower my salinity for a little over 2 months. For the first year of my tank, I used pre mixed salt water from my LFS. The salinity was way to high so I bought an Rodi machine to try and fix the salinity levels. I have only been putting RODI water in the tank which temporary helps the levels down to a normal level right after my water change. But after a week, the levels go up back to way over the top. How is this possible since i’m not using salt water? Could it be my bucket since I use it to remove water from the tank too?
