What It Means
Spa Salt / Mineral / Bromine Feeder Not Maintaining Residual
Likely Causes
- Cartridge depleted or expired
- Flow path blocked
- Water age/TDS high
- Salt or bromine level outside range
- Cell or feeder scaled
- High bather load
Next Checks
- Verify sanitizer with a manual test before trusting the feeder
- Capture feeder model, cartridge date, salt/bromine reading, and water age
- Clean only per manufacturer directions
- Reset water with drain/refill when age or TDS is the root issue
- Do not mix incompatible sanitizer systems without a full conversion process
