On my 55 gl tank, I was blowing through 5-6 5gl jugs of water every 2 weeks which included a water change, I would assume you are about the same? When we first started the tank, we were using untreated (gasp) tapwater for about 5 months then, switched over to ro from the store for 3, then bought my own unit. You'll get tired of hauling water, or needing some in an emergency and not having it available (happened to me). I had set up an emergency tank and then the water hauling got annoyingly painful as I was going through 6-8 in a week, that sealed the deal to get the unit.....Mine was set up under the kitchen sink, then relocated to the basement, was a pretty simple move but that's easy for me to say, I just supervised!
