Harveys block salt can be used in any block salt water softener.
Each bag contains two 4kg blocks giving a total bag weight of 8kg. Minimum order value for FREE delivery is 3 bags.
These refill bags have an easy carry handle and are made of protective material so you can store safely in an outbuilding.
As a very rough rule of thumb you’ll use around one block per person per month. Often our customers do buy in bulk or order via our salt club subscription service to ensure a steady supply.
