Hydro Dioxide Biofilm Eliminator - 40g Tablet
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.
- Deep penetration technology designed to target hidden biofilms and resistant pathogens.
- More effective, faster acting, and safer by design than chlorine.
- No harmful by-products including THMs, HAAs or chloroform.
- Improves air quality, reduces chemical load and supports sustainable operations.
- Effective across a broad pH range and designed for proactive water management.
- Biofilms, chlorine-resistant pathogens and organic contamination.
- Legionella, Pseudomonas, E. Coli, Giardia, MRSA and Cryptosporidium.
- Viruses, parasites and fungi.
- Isolate your chlorine, redox & pH probes from the hot tub or pool water.
- Isolate any chlorine or bromine feeder prior to product application.
- For systems with a cartridge filter, remove & clean the cartridge, then return to service before treatment starts.
- CAUTION: Do not use the hot tub or pool during DiOx Ultra treatment.
- Refer to the dose rate table below for the number of tablets required for treatment.
- Wear suitable protective gloves & eye protection when handling product.
- Open the sachet(s) and carefully drop the required number of tablets around the hot tub or pool perimeter with the pump(s) running.
- After 15 - 20 minutes, backwash your filter. The hot tub or pool will be safe to use after 8 hours or immediately if draining and refilling with fresh water (assuming sanitiser & pH levels are correct).
- Add one tablet to 20ltr of water using a clean bucket and allow the tablet to fully dissolve.
- Apply the solution to biofilm covered surfaces such as floatation aids, covers, channel grates, pool sides and changing areas. Leave for 5 minutes and then wash off with clean water.

FREQUENTLY ASKED QUESTIONS
What is pool biofilm and why does it form?
Biofilm is a slimy layer of microorganisms, including bacteria and algae, that attaches to pool surfaces and hidden plumbing. It forms when free-floating bacteria find a surfaceWhat is pool biofilm and why does it form? to cling to and secrete a protective, sticky organic matrix. Warm water, poor circulation, and inadequate sanitation create the perfect breeding ground for this matrix to grow rapidly. Once established, this thick shield strongly protects the underlying bacteria from standard pool disinfectants.
How does biofilm affect chemical usage?
Because biofilm acts as an impenetrable shield, standard sanitizers like chlorine struggle to pierce it and kill the hidden bacteria. Your pool system will constantly consume more chemicals trying to break down this barrier to maintain safe, clean water. This creates a frustrating and expensive cycle of over-dosing sanitizers and algaecides without ever solving the root problem.
Can biofilm reduce water circulation?
Biofilm thrives in the dark, hidden environments inside your pool's plumbing and filtration systems. As the slimy layer thickens inside the pipes, it restricts the internal diameter and creates unnatural friction. This forces your pool pump to work much harder, significantly reducing the overall water flow and lowering the daily efficiency of your filtration system and increasing the electrical consumption at the same time.
What effect does biofilm have on surfaces?
Biofilm can severely degrade the condition of your pool's coating over time. The living microorganisms within the slime produce acidic byproducts that can permanently stain, discolor, and slowly deteriorate liners, tiles, and plaster. If left untreated, this persistent organic growth causes irreversible damage that requires expensive surface repairs or complete liner replacements.
Does biofilm cause equipment corrosion?
The localized environments created beneath the biofilm layer trap corrosive byproducts and moisture directly against metal surfaces. This aggressive process, known as microbiologically influenced corrosion (MIC), attacks metallic pool equipment like heat exchangers, ladders, and pump components. Over time, this targeted corrosion drastically shortens the lifespan of your most expensive pool hardware.
Why are water analysis probes malfunctioning?
Biofilm easily coats the delicate, submerged sensors of your water analysis probes, such as pH and redox (ORP) meters. This sticky organic layer acts as an electrical insulator, preventing the probes from accurately reading the actual water chemistry. As a result, your automated dosing systems receive false data and may dangerously over-dose or under-dose chemicals into your pool water.
How does biofilm change water appearance?
Even if your automated chemical levels seem perfectly balanced, biofilm makes your pool water look dull, cloudy, and noticeably less sparkling. The constant shedding of dead bacteria and organic matter from the biofilm layer overwhelms your filter and scatters light in the water. In advanced cases, you will notice visible slippery patches or a murky green and brown tint clinging to the pool walls.
