Spa care

Spa water care basics (and what to check before you call)

A spa is a small body of water kept hot and used hard, which is why spa water needs a lighter touch and a closer eye than a pool.

A simple routine

Check sanitiser and pH with strips before each soak or at least weekly, rinse the filter cartridge regularly, and bring a sample of spa water into the shop for a full test when you want a second opinion.

Do not overdose

Spa volumes are small, so a pool-sized scoop of anything is a big dose. Measure to the label, run the jets to circulate, then retest.

If the spa stops heating

Note any error code on the control panel and check the water temperature with a thermometer if you can. Those two details tell us a great deal before we arrive, and sometimes point to something as simple as a dirty filter restricting flow.

Filters and cartridges

A clogged cartridge is behind a surprising number of spa faults — poor jet pressure, heating cut-outs and cloudy water. We stock cartridges and parts for common spa brands in store.
