As you research, I have two of the 17g Lifegard and 1 IM Nuvo 10 gallon and use a small table unit which also looks cool. Easy to use and place on countertop, Rkin.com. I just make up bottles in advance so they can air out ph. Plus you can drink if you want; I use the Zero Installation Purifier with the alcapure so I don't have to remineralize as much. Have had it for two years and not yet needed to replace the filter. BTW, I found my IM Nuvo 10 gallon cube very difficult to plant and stock, maybe go a bit larger?
Fish+Plants thanks you!!
