Steve, Using the Aquarium Pharmaceuticals Tap Water Purifier surely is
the high priced spread. The less expensive way to go is tha Kati/Ani
system the initial out lay is about what you would pay for a RO system
but the resins can be recharges for ever. If you already have an AP TWP
that can be changed from a mixed bed system to a separated system and
similarly recharged. My water after paying for 3 TWP units was $0.006
per gallon. YMMV
