I’ve always used pure RO (then added minerals) for water changes on my Cherry shrimp tank but I now want to avoid the hassle of buying the stuff (and the expense/waste of making my own).
However, my tap water comes out at 40ppm nitrates so that’s a concern. I have one of those Pozanni nitrate filters so if I zap the tap water what am I left with? Would it need mineralisation or treatment of any sort? How long could I keep it in 25l containers as stock?
