Truly and honestly, the only thing you need for the water here is a good carbon filter. RO water with little or no TDS has NO nutritional value, and cannot be used by the body. Water needs to have minerals and dissolved solids to be useful. Also absolute pure water doesn't exist in nature(aside from maybe clouds)
The difference between stupidity and ignorance. Ignorance is doing something wrong and not knowing better. Stupidity is knowing better, but doing it anyway. Don't be stupid!
