Swimming pool and hot tub chemicals

Portland Pool Products produce a complete range of high quality swimming pool water treatment chemicals and products.

Portland chems 1Not all swimming pool chemicals are the same! Portland Pool Products’ chemicals and water treatment products have been selected and carefully graded to ensure optimum performance and best value for money for our customers by some of the country’s most experienced pool engineers and service technicians. People with decades of experience servicing and treating pools and know exactly what makes a great value treatment product; and what doesn’t! Our products are not the cheapest on the market. However, they are the best value; and manufactured and packed right here in the UK. Our granular products are graded for even granule size and rapid dissolution, so you don’t get large undissolved chunks which can stain liners or damage tile grout, and cause a potential hazard to the feet of swimmers. They also have a low dust content, so that you’re not exposed to a harmful dust cloud when you pour it out, and to prevent a potentially expensive purchase blowing away. And if a product says it has an active ingredient concentration of 55%, then the active ingredient content is 55%. We don’t pack the product out with inert fillers so we can sell it cheaper.

Our tablets are formulated and pressed to ensure even erosion to maximise their operational lifespan and an even and consistent feed of dissolved chemical into the water. They don’t crumble away within hours of being placed in your skimmer or dispenser, giving a huge slug of chemical into your pool water for a couple of hours, and then no protection for days after. Our liquids are formulated at concentrations which make them effective, go a long way, and give you great value. They’re not watered down so that we can sell them cheaply. The Portland Pool Products range is packaged with easy to identify colour-coded labelling and include the following products.
