Product Details

Hydro Dioxide

Advanced Chlorine Dioxide Technology

Warm hot tub and swimming pool water can provide the ideal breeding ground for bacterial growth. As bacteria starts to form on surfaces and in hot tub pipework, biofilm can begin to form. Biofilm is extremely resistant to chlorine. AquaSPArkle DiOx Ultra will effectively clean hot tub and swimming pool pipework and surfaces.

Hydro Dioxide is a fast dissolving 40g Chlorine Dioxide tablet designed to quickly remove and prevent the formation of biofilms within hot tubs, spas and swimming pool systems. According to GreenTech International, Hydro Dioxide is almost 3 times stronger than chlorine and up to 100 times more effective at removing biofilms.

Questions & Answers

Judith5/21/2026

Is this product also suitable for whirlpool baths? Thanks

Rosie answered:
No, The Hydro Dioxide tablet is 40g so the solution would be too strong for a whirlpool bath. It could also cause some issues if used indoors especially if the area was poorly ventilated. It's much better suited to an outdoor hot tub or pool. I would try Pure-Spa Whirlpool Bath Cleaner and Degreaser and the Pure-Spa Sanitiser Tablets. These work very well for whirlpools.

What is Biofilm?

Rosie answered:
Biofilms are slimy layers of microorganisms that form inside water systems like pipes, and filters, making them very resistant to cleaning and harmful to bathing water quality. Biofilms harbour harmful bacteria that can contaminate Spa water and cause infections. Normal Chlorine just washeses over them. But Hydro Dioxide will destroy Biofilm
