are these compatible with Harvey's Water softner system?

We don't have Harvey's Water softner system so can't confirm for sure that whether its compatible or not. But as I understand most of these salt blocks come in same size so it should be compatible with most water softner systems

Are these blocks or tablets - 18 'blocks' at 1x1x1cm - what are the actual dimensions of each block?

These are definitely blocks and they measure 10cm x 12.5cm x 30cm each
