Swimming Pool Chemicals, Spa Water Chemicals & Water Testing Kits

We are a long established independent manufacturer and supplier of chemicals to industry and can trace our origins back to the late 1790's when our company was founded in Glasgow, Scotland. Today our distribution section in the UK operates 7 strategically located chemical stores & in addition to our industrial sales, via this website we offer a broad range of swimming pool & hot tub chemicals and water testing instruments which can be purchased on-line securely. Everything we offer is held in stock normally at our pool chemicals warehouse in Kent thereby minimizing back-order delays. Please note that this website does not ask for, record or store any credit/debit card details - When payment is made you will be re-directed away from this site to secure payment facilities operated either by Worldpay or PayPal.

Water as supplied via the UK mains is rarely properly balanced for pool use and presents many challenges for the pool operator to overcome in order to provide clean, healthy pool water and prevent bather ill-health and/or damage to expensive equipment. Calcium Hardness in the UK ranges from too hard in the south and east of the country through to too soft in the west and north, and the high level of phosphates, which acts as a food bank for algae and bacteria, is a huge problem nationwide. We supply solutions to these challenges and many more helping to deliver the enjoyment and wellbeing that bathers expect.

Take control of your pool - it's your health, your wellbeing, your enjoyment, your money... your choice!

If you can't wait for us to deliver (normally within 3 working days) you can choose the option to collect your order from our warehouse at Northfleet in Kent. Our warehouse is open from 9 am until 4pm (Mon-Fri) but closed at weekends and bank holidays - See our Shipping and Returns section for more information.

  • TIRED OF FIGHTING THE GREEN MONSTER? Phosphate Removers - Dosing a harmless phosphate remover will stop algae bloom and inhibit the growth of bacteria. In the UK most water companies dose ortho-phosphoric acid to the mains supply so as to control lead from leeching into water from lead pipework in our homes. Together with phosphates arising from other sources (including garden fertilizers, washing detergents and other pool chemicals etc) this breaks down into organo-phosphate which is a primary nutrient for algae and bacteria. In the UK it's not uncommon to find phosphate levels up to and around 2500ppb in pools whilst the recommended maximum is ZERO ppb. Removing phosphate will deprive algae of its food stopping bloom, and at the same time support the pool sanitizer by inhibiting bacterial infection. Better for bather health, better for the environment and overall better than using chlorine shocks or algaecides. Phosphate removers work by precipitating phosphate out of the water to the filter from where it is washed away by filter cleaning. Whilst the use of a phosphate remover will benefit all pools (public or private) we strongly recommend, in particular, that a phosphate remover is used for any pool which is not equipped with an automatic sanitizer dosing system. Your reward for removing phosphates is that less sanitizer will be consumed thereby on balance saving time and money. 
  • Chlorine-free Oxidizers - Using chlorine as a "shock" to oxidize unfilterable organic matter is difficult to apply properly even for the experts, and results in significant pool downtime while the chlorine level retreats to safe bathing levels. Using a non-chlorine shock is just as effective (if not more so), is kinder to our environment, better for bather health and the pool down time is brief (normally between 15 - 30 minutes).
  • Coagulants - Dosing a coagulant is considered to be essential in maintaining healthy water. No filter by itself will remove all "undesirables" and dosing a coagulant will help the filter to trap very small particulate matter including Giardia & Cryptosporidium oocysts which (unless your pool is equipped with an AOP sanitising system) are not killed normally by the pool sanitizer.

Please note that we do not provide pool maintenance services. However we are happy to provide advice on the application and use of pool chemicals and offer recommendations covering any pool water problem in good faith based on our knowledge which has been developed over many years of experience. Our team includes qualified members of The Institute of Swimming Pool Engineers.
