About Pool Chemicals

Keeping pool water crystal clear comes down to three things: sanitiser, pH balance and regular shocking. We stock the full range of chlorine, bromine, pH+ / pH–, algaecides, clarifiers and test kits used by UK pool owners and trade installers.

Buying a complete starter kit costs less than buying chemicals one at a time, and our team can recommend the exact dosage for your pool volume — just tell us the litres or pool model.

Frequently Asked Questions

Chlorine is more cost-effective and the standard choice for outdoor swimming pools. Bromine is gentler on skin and more stable at higher temperatures, which makes it the better choice for hot tubs and indoor pools.
