Hot tub care plan
Draining and refilling your hot tub
Even well-looked-after hot tub water gets tired. Soaps, oils and dissolved minerals build up until the water foams, smells or will not balance. Draining, cleaning and refilling about every three months gives you a fresh start. It takes most of a day, mostly waiting for the tub to drain and heat up.
Allow 1 day, plus 24 hours to heat and settle

Tips
- Refill every three months or so, sooner if the tub is used daily or the water foams or will not balance.
- Hard-water areas: keep pH at the lower end (7.2-7.4) to reduce scale on the heater.
- Soft-water areas: raise hardness to about 150 ppm to reduce foaming and protect the heater.
- Set a reminder in the app for your next refill.
Safety first: add chemicals to water, never water to chemicals. Never mix products - add one at a time with the pump running, and store them apart, dry and out of reach of children.
