Can I use tablet salt in the HarveyArc model?
The Mini Curve salt block is made specifically for the HarveyArc. The Mini Curve salt is lighter (2.15 kg), smaller and easier to handle and much more convenient to store than large tablet bags. The Mini Curve salt blocks can be stacked for a higher salt capacity – so you can refill less often. Made from high Grade A / food quality salt, the Mini Curve salt block doesn’t contain any anti-caking agents or unwanted minerals so it won’t damage your water softener.
