I try not to store mixed saltwater for long, it gets slimy and smells musty after several days. I keep five 5G drinking water type jugs and the 23 gallon Rubbermaid ATO container of RO/DI at all times and can mix up my 30G Rubbermaid on wheels with new saltwater in a few minutes when needed.
One advantage of having the RO/DIunder the sink is you could add a $59 drinking waterkit and use the RO only for drinking and icemaker too so it serves double duty. We have used RO of drinking and ice for about 20 years now and love it. It was much easier to justify the purchase to the wife at the time. We fill drinking water bottles half way, stick them in the freezer, pull it out and top it off with RO and have cld water for hours. Saves a fortune on buying bottles of drinking water plus all the landfill space or recycling costs too.
