Okay im kinda confused about the procedd a little since im new so bear with me. I want to remove some water and replace with rodi. And im kinda confused about the process its my first sump. So do i mark where the water is right now in my sump? Where i like it to be? And then do the water change? And then when i fill the tank i keep my filling till i get to that line?
