Four Stages!!! Wow! Anyone else do this? used to run one and I am now running two...

I saw a quad unit that was being sold either by AWI or Bulk Reef Supply and I have an old RODI that I had put together after a school one broke (lots of mismatched parts). I decided to simply do it myself. Not sure that it works the same way as the quad I saw advertised as mine goes through one stage at a time, but I figured I have the stuff, the DI will discharge at the same pace it would normally anyway, and I'm going to regenerate it so I might as well get some clean DI water that will last a long time. One thing I saw advertised was that they suggest you swap the cartridges from one to the next, but I'm not sure I'd ever do that as the older ones will release stuff after they are fully used up, so I figure when they get used up I can catch what comes out with the next stages. I'm more or less using one of those car washing sized ones when it boils down to it, or the equivalent of an industrial one.
