Wow, really?! ANOTHER FLOOD! GRRR!!! Sooooo angry!

[zeroinverse]

zeroinverse... btw what does that mean? inverse of zero would be 1/0 so infinity?
Either way, I've seen lots of stacked setups like that which works great for small footprints (basically as wide as a can is) I'm guessing one is saltwater the other is fresh? Or are they both salt? The bottom can has to be salt at least otherwise I couldn't imagine putting salt into the top one.

Yes, I used to own an Infiniti G35. So "infinity"

Top container is where RODI water goes in and then drains down to bottom whenever I need to make saltwater. It has a float valve on top so my RODI container is always full (for emergency saltwater making, for topoff purposes, and as emergency water supply).

I can't imagine climbing up a ladder all the time to put salt into the top container.
