Hot tub care plan

Hot tub weekly routine

Hot tubs hold a small amount of warm water shared by several people, so they need a little attention every week. This routine keeps the water clear, comfortable and safe, and helps it last until the next refill.

About 10 minutes a week

Checklist

0 of 7 done

1. Test before each useTest before each use, or at least twice a week. Photograph the strip in the app - it knows whether your hot tub uses chlorine or bromine.
2. Balance alkalinity, then pHKeep alkalinity at 80-120 ppm and pH at 7.2-7.8. Add one product at a time with the jets running and the lid open, and wait 20-30 minutes before retesting.
3. Keep sanitiser in rangeChlorine 3-5 ppm, or bromine in the range the app shows. Top up the bromine dispenser, or add chlorine granules after each use.
4. Shock once a weekShock with the jets running and the lid open for 20-30 minutes. Shock again after a busy session. Wait until sanitiser is back in range before getting in.
5. Rinse the filterTake out the cartridge and hose it down between the pleats every week or two. Deep clean it monthly with a filter cleaner and replace it about once a year.
6. Wipe the waterline and coverWipe away the greasy line at water level with a soft cloth, and clean the underside of the cover.
7. Check the water levelTop up so the water covers the skimmer opening, then retest after adding fresh water.

Tips

Shower without soap before getting in and rinse swimwear in plain water - it is the best way to prevent foam.
Keep the lid on when not in use to save heat and keep debris out.
Plan to drain and refill about every three months - see our refill plan.
Never mix chlorine and bromine products, and never add chemicals with people in the tub.

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.
