What are the ideal chlorine levels for a hot tub?

Keep chlorine between 3 and 5 parts per million (ppm). That range keeps the water properly sanitised and heads off the health risks that come with neglected water.

How do I test my hot tub water chemistry before adding chlorine?

Reach for a good hot tub testing kit, which usually comes with strips for pH, total alkalinity and sanitiser. Dip a strip in for three to five seconds, lift it out and match the colours against the chart supplied.

How should I prepare chlorine granules for my hot tub?

Weigh out the exact amount of granules for your tub on a digital scale. Dissolve them in a clean bucket with a little warm water, stirring until they have gone completely, so you end up with a concentrated solution you can spread evenly through the tub.

How long should I circulate the water after adding chlorine?

Once the chlorine is in, run the jets for roughly 15 to 20 minutes. That mixes it right through the water so the whole tub gets properly sanitised.
