Hot Tub Starter Kits

Sanitiser, pH increaser and reducer, an alkalinity increaser and a way to test. Balance alkalinity first, then pH, then sanitiser. A starter kit covers all of it in one order rather than four.

Balance alkalinity and pH before adding sanitiser, because chlorine works poorly outside the correct pH range. Then dose to 3 to 5 ppm, run the pump for 20 minutes and wait a further 20 before getting in.

The 500g Collection suits a first fill on a smaller tub. The Kilo Collection lasts longer and costs less per dose. If you also need a filter, the two filter bundles pair the chemicals with the right cartridge.

Yes. Water care is identical whatever the tub is made from. Any spa holding heated water needs sanitising and pH balancing to stay safe and to protect the heater and filter.

Alkalinity first, because it buffers everything else. Then pH, then sanitiser. Add one at a time with the pump running, wait 15 minutes between different products, and never mix chemicals together.
