Your going to need a source of RO water, RO/DI would be much preferable. It could be the lfs, supermarket, water store, or a unit. In the long run, and I'm only talking a year or so here for your 10 gallon, you'll probaly find a unit for your house most economical. Plus your family gets a source of drinking water instead of buying bottled water.
