|---|---|
| Upkeep | Water chemistry is the whole job: hold pH between 7.0 and 7.8, sanitise with chlorine granules or bromine, and drain and refill every 30 to 50 uses no matter how clear it looks. By frequency that is roughly every 4 to 12 weeks on one or two plunges a week, 1 to 4 weeks at three or four, and every 1 to 7 days for daily or multi-person use. |
| What you rebuy | Water test strips, Chlorine granules or bromine tablets, pH up / pH down, Stain and scale remover |
