[hypoxia]

I looked at some of the deionization systems on the market, a neighbor gave me a water softener which started me on this path.  I ended up getting a Pentair Big Blue 3/4" Housing along with a refillable insert for that cartridge and 1 cubic foot of DI Anion/Cation resin.  One cubic foot of resin should be good for about 8 cartridge fills.  It's a very simple system, I haven't tried it yet.  I would like to get a dedicated hose and have looked at the expandable hoses, they have bad ratings though.  Has anyone else gone down this path?
