here's some pics of the stand.
That is my waterline coming out of the wall. My RODI will be in the stand. It will be a manual operation, I am not plumbing it directly into the sump. I have 2 x16G Tall aquariums, one for mixing saltwater and the other for ATO. The ATO tank will double as the quarantine tank when needed and be replaced with a 5 Gallon bucket for those times. The idea is to have everything from making and mixing water and waterchanges to happen in the stand. I even have a drain line in the wall that goes under then out the side of the house into the bush.
