FAQs - Water Softener Salt Blocks

What’s the difference between granular, tablet, and block salt for water softeners?

All three forms are used for regenerating water softeners, but the choice depends on your system.

  • Granular salt – This is free-flowing and often used in older or industrial softeners.
  • Tablet salt –  most common choice for domestic units, offering convenience and consistent dissolution.
  • Block salt – designed for modern cabinet softeners, making handling and loading easier.
Is SPECTRUM softener salt certified for quality and safety?

Yes. All SPECTRUM softener salt is produced to EN973 Type A certification, ensuring the highest standard of purity and safety for water softening applications.

How does softener salt help protect my water softener and system?

Softener salt regenerates the resin inside the water softener, allowing it to continue removing calcium and magnesium from hard water. This prevents scale buildup, protects your system, and ensures consistent soft water performance.

Which type of softener salt is right for my system?

The best option depends on your water softener. Tablet and block salt are ideal for most domestic cabinet softeners, while granular salt may be recommended for certain industrial or older systems. Always check your softener manufacturer’s guidance to choose the most suitable type.
