Even if you installed a water softener, you would still need to fill it with salt every now & then (and wouldn't really want to be drinking softened water either, which is why you would always have an un-softened mains tap).
Citric acid can be used to clean your dunny too (which will have scale build-up). And your waskhing machine. And your coffee machine. And your [anything that uses water]. And it's magnitudes cheaper than any branded crap, which just contains citric acid and colouring.
