Troubleshooting Low Bromine with the Blu Fusion Salt System 

 

Low bromine readings on the Blu Fusion Salt System are usually caused by a few common water chemistry or circulation issues. Before assuming there is a problem with the system itself, there are several simple things that can be checked and corrected quickly. 

 

Here are the most important things to check when troubleshooting low bromine levels: 

 

Check Your Sodium Bromide (Salt) Level 

Your Blu Fusion Salt System needs the proper sodium bromide level to generate bromine effectively.

 

  • Ideal range: 1600-1700 ppm. 
  • Too low: The system cannot generate bromine. 
  • Too high: The system has an overload and needs fresh water.

 

Ensure Proper Filtration Time

 

Your spa needs enough circulation time for the system to properly sanitize the water. 

 

  • Recommended circulation: at least 8 hours per day.
  • Poor circulation can lead to weak bromine production and inconsistent readings. 

 

Check the Output Setting

 

Sometimes the issue is simply the output level on the salt control.

 

  • Verify the system is running. 
  • Check the output setting is high enough for your spa usage. 
  • Heavy use may require temporarily increasing the setting. 

 

Test for Phosphates 

 

High phosphate levels can interfere with water quality and sanitizer efficiency. 

 

  • Test water for phosphates.
  • Treat with phosphate remover if levels are elevated. 

 

Phosphates are commonly introduced through rain water, lotions, detergents, and organic debris. 

 

Test for Metals in the Water

Metals such as copper or iron can create water chemistry issues and interfere with sanitizer production. 

 

  • Test for metals.
  • Use a metal remover if needed. 

 

Check Conductivity Level

 

Conductivity is extremely important for proper salt system operation. Inspect the cell regularly and clean if scale buildup is visible. 

 

If conductivity is too low: 

 

  • There may not be enough salt in the water. 
  • The salt cell may not be functioning properly. 

 

If conductivity is too high:

 

  • There may be too much salt in the water. 
  • Scaling or buildup may be present on the salt cell. 

 

Tip: Conductivity should be between 1.0 and 1.4
