Pool Chemicals

Pool chemicals are an essential aspect of any swimming pool because they keep algae and bacterial growth at bay. There’s much more to the correct makeup of pool chemicals than just Chlorine. At Poolwerx, we stock a wide range of industry-leading chemicals such as algaecides, balancers, stabilisers, cleaners, stain removers, spa chemicals and much more!

When it comes to formulating the correct pool chemicals mix for swimming pools, there is no one plan that fits all. Speak with your local Poolwerx today to create a tailored plan for treating your pool.
