I'm blessed with very soft water, so I don't know much about RO & DI.

I used my Magnum 220 as a diatom filter for a while.  Diatom filtration
has its advantages - the biggest being  that the file-leaved plants
like Limnophila (Ambulia) don't get their leaves smothered in detritus.

I used to run the diatom filter continuously.  Cleaning and replacing the 
micron cartridges eventually became a nuisance, so I went back to regular
filtration.  If you run the filter for just a couple of hours every day,
you may not have a problem.
