Keeping pool water in good condition is the key to a clean, safe swim. Five chemicals do most of the work: chlorine granules, bromine granules, calcium hardness increaser, pH balancers and stabilisers. Each has a clear job in keeping the water clean and safe.

Chlorine granules clear bacteria and microorganisms, while bromine granules give you an alternative that suits spas and indoor pools. Calcium hardness increaser holds calcium at the right level so your equipment and surfaces do not get damaged. pH balancers and total alkalinity stabilisers keep pH in the recommended range, which fends off skin irritation and equipment damage. Stabilisers shield chlorine from sunlight, algaecides stop and treat algae, and flocculants help sand filters do a better job.

Always follow the safety guidance and never mix different chemicals. Add them one at a time, in the right order, so they work as intended and you avoid any hazards.

For products, tablets like In the Swim 3-Inch Chlorine Tablets and bromine tabs are well rated for holding back algae and bacteria and keeping water clean and odour-free.

Use the right chemicals and keep up with maintenance and you will have a pleasant, safe pool to enjoy. For advice tailored to your pool, talk to a pool professional, and if you need chemicals in bulk, head over to Zagosa Spa & Pool.
