Maybe I’m wrong, but long term it seems as though an RO or RO/DI unit will be more economical than a DI unit alone (such as the Kati/Ani unit (unless you try to reconstitute the filter media, which sounds like a major pain in the rear), a Tap Water Purifier (I’ve used this on my 20 gallon since the tank requires modest water changes and top-off). I think I read in the FAQs by Steve Pro or someone that the small Kati/Ani unit that sells for about $139 can knock out about 200 gallons of purified water (high cost per gallon), and my little Tap Water Purifier can knock out about 30-35 gallons at somewhere around $13 to $15 dollars a filter. Under those scenarios, and absent trying to renew the media, the little old Tap Water Purifier is more economical than the Kati/Ani unit. Anyway, I digress.
