Belmont B500 DUWL Intro Kit


  • 2 periodic shock tests
  • 2 Periodic shock treatments
  • 20 daily maintenance sachets

Our recommendation: This convenient kit gives you all you need to discover the benefits of B700 and B900 for DUWL maintenance, testing and treatment. Start with the shock test – if this detects the presence of biofilm then use the shock treatment to remove it. You can then start ongoing maintenance using the sachets.
