It is not as likely carbonate hardness (CO3--) as non-carbonate hardness,
primarily Ca++. The snails draw it from the water to build their shells.
Without enough, they languish and die. Your RO unit removes it. You can add
RO Right to restore trace amounts of minerals, or any of a number of calcium
compounds, like CaCO3 or CaCl.
