I'm one of those that uses pure tap water still. I had a RO unit in the past but didn't like the amount of wastage as the unit gave about 1 litre of good for every 10+ of waste. Even the garden didn't need that much. Next pay I'll grab a RO again, primarily for top ups and to reduce phosphates and to adjust TDS if necessary, but that currently sits around 150 - 170 without too many issues, bit of calcium from a Reef Builders mix goes in each couple of weeks but only a capful if that.
