Salt doesn't increase hardness. What you're talking about here is high KH but low GH and low TDS - and by the way doesn't the fact that the tetras like it and the mollies don't demonstrate that it's TDS which matters to fish rather more than pH?
Fortunately the African Cichlid salts which are widely available solve exactly this problem. Alternatively, Epsom salts will do it more cheaply.
