I am interested in everyone's general experiences with this water
conditioner. I also have questions about how I would use this as a purified
source of drinking and cooking water in addition to use with my aquariums.
I am having a terrible time with mineral build up in my aquariums plugging
filters and leaving a hard mineral scale on everything so, this is where my
search started.

For myself, I have considered going to bottled water for drinking use but,
it seems like I should be able to "wire" this under my kitchen sink and hook
up some sort of dedicated faucet. Is this a reasonable thing to do? Is it
cost effective? Would I be better off getting a ~$150 5 gallon bottle
dispenser and lugging the bottles around for my own use? The reverse
osmosis seems to offer what I am looking for getting rid of the Arsenic and
other minerals that concern me (we are within EPA limits from our municipal
water source but, we are above the tighter standards that were recently
rejected for political reasons).

Thanks for you assistance!
