Hydro Dioxide quickly removes and prevents the formation of biofilms. Almost 3 times stronger than chlorine and 100 times more effective at removing Biofilms (2kg 50 x 40g tablets) Hydro Dioxide supports sustainable water management by reducing biocide demand, minimising water changes, and preventing system fouling - improving water and air qualitywith fewer chemicals. Manufactured in the UK, aligned with Net Zero 2025 targets and a lower carbon footprint. Fully compliant with GB BPR, ISO & OHSAS accredited, and recognised inHSG282 for Legionella control. Hydro Dioxide conforms to EN1276 (log rate 99.999%) UNDERSTANDING BIOFILMSBiofilms are resilient, living communities of microorganisms including legionella andpseudomonas aeruginosa which produce a protective slimy layer called a biofilm. The biofilm will quickly attach itself to many swimming pool, spa and hot tub surfaces and is resistant to chlorine even at high levels. Are Biofilms harmful? Potentially very, pathogens such as pseudomonas aerginosa, legionella, Giardia are locked and protected inside the Biofilm. But when water chemistry, temperature, pressure, or flow changes, these very dangerous pathogens can break loose. Where does it grow?Swimming pools, Spas and Hot tubs offer the perfect warm high nutrient environment forbiofilms to grow. Biofilms attach themselves to internal pipework and skimmers, fittingsincluding lights, safety covers, floor wall and step surfaces, scum troughs and gulleys, balance tanks, cartridge filters, filter media, showers and even tile grout. The oil, skin, sweat and other pollution from bathers along with an increased water temperature provides an ideal recipe for Biofilms to thrive Maintenance Dosing Rates (Dosing monthly) Pool Volume M3 Residential: Monthly Up to 25 M3 3 Up to 50 M3 4 Up to 100 M3 6 Up to 200 M3 12 For heavy contamination double the above dosage Other applications Dosage Application Pool balance tanks 4 tablets For heavy contamination General cleaning 1 tablet per 20lts water For floatation aids, covers, grating, mats, drains
