Spa water care checklist
Spa sanitizer, salt, mineral, and bromine feeder checklist
Spa water changes fast. Before blaming a feeder, cell, or cartridge, capture manual test results, water age, bather load, cartridge dates, and whether ozone/UV/AOP is actually operating.
Capture first
1. manual sanitizer test2. pH and TA3. cartridge date4. feeder flow path5. water age6. drain/purge history7. ozone status8. bather load
Field-safe checks
- Do not use pool-size dose habits in spa-size water volume.
- Verify manual readings before trusting feeder or app claims.
- Replace depleted cartridges and clean restricted paths before hardware assumptions.
- Drain/refill may be safer than chasing unrecoverable old water.
