To share. My ATO only 10 g. If I have to pump to fill anyways, I might as well pump direct from RODI. I considered second container for RODI water only in garage (completely separate), but then what the point, still needs to be pumped back to saltwater bucket.
@mike550 that is exactly what I am going for. 1 bucket (in closet) to mix RODI water and salt, then pump back to display tank as needed during water changes.
I got 50 ft RODI line rolled up, I just take to where it needs to go (ATO or mixing container) as needed. Thanks everyone. Glad this helped more people!
