Standard tablets release free chlorine to maintain water safety, but they are quickly consumed when fighting hidden biofilm. By using Hydro Dioxide (ClO₂) to completely eradicate the biofilm matrix, your chlorine is no longer wasted on the plumbing walls. This means you will use significantly fewer tablets throughout the season while maintaining perfectly safe, crystal-clear water.

Liquid chlorine and salt electrolysis systems both provide excellent continuous sanitation, but they struggle against established slime. When you eliminate this organic burden with Hydro Dioxide, your automated dosing probes (ORP/Redox) will register clean water much faster. Consequently, your liquid chlorine pump will inject far less chemical, and your salt chlorinator cell can run at a much lower power setting, greatly extending its lifespan.

UV systems are highly effective at neutralizing free-floating pathogens as they pass through the light chamber. However, UV light provides no residual protection in the water and cannot reach the biofilm growing inside dark pipes or filter media. Adding Hydro Dioxide perfectly complements UV by deeply cleaning the entire plumbing network that the light simply cannot reach.

Hydrogen peroxide and potassium monopersulfate (KMPS) are fantastic for burning off organic waste and keeping water sparkling, but they cannot penetrate biofilm. By letting Hydro Dioxide handle the tough job of destroying the biofilm shield, these alternative oxidizers can focus entirely on clarifying the water. This combination ensures a gentle, odorless swimming environment with absolute microbiological safety.

Biofilm acts as a massive sponge that constantly consumes your standard sanitizers. Eradicating it drastically lowers your daily chemical consumption and saves you money. Furthermore, clean pipes have a wider internal diameter and lack sticky friction, allowing your filtration pump to push water more easily. This improved hydraulic efficiency leads to noticeably lower electricity bills over the swimming season.

Microorganisms living inside biofilm produce localized acidic waste that slowly eats away at pool liners, tiles, and plaster. They also trigger microbiologically influenced corrosion on expensive metal components like heat exchangers, sensors, and ladders. By proactively removing the biofilm with Hydro Dioxide, you stop this hidden degradation, preserving your pool's aesthetic appearance and delaying costly equipment replacements.

Our subscription model is designed for preventative maintenance and we recommend a 40g tablet every 4 weeks.

Unlike traditional sanitizers, Hydro Dioxide (ClO₂) generates in situ a dissolved gas (ClO₂) that does not react with harmless organic matter in the water. This unique chemical selectivity allows it to easily penetrate the thick, sticky shield of the biofilm without losing its strength. Once inside, it actively destroys the cellular walls of hidden pathogens, including dangerous Legionella pneumophila and common water bacteria like E. coli or Pseudomonas.

Chlorine tablets rely on free active chlorine, which struggles to pierce the biofilm matrix and ends up just bleaching the surface layer. Additionally, tablets add cyanuric acid (stabilizer) to your water, which can quickly build up and block the chlorine's sanitizing power. Hydro Dioxide completely eliminates the biofilm from the roots and operates entirely without adding any cyanuric acid to your pool.

Saltwater electrolysis is a very convenient way to generate free active chlorine, but it produces the exact same chemical as traditional liquid chlorine. Therefore, it faces the same limitations: it cannot deeply penetrate established biofilm to kill the bacteria hiding inside. Hydro Dioxide works entirely differently as an oxidizing gas, actively stripping away the biofilm layer that salt-generated chlorine leaves behind.

Liquid bleach is a very convenient way to inject free active chlorine quickly with high concentration (0.15g/ml), but its active chlorine concentration within the barrel drops very fast (6 month lifetime). Therefore, it faces the same limitations as chlorine tablets: it cannot deeply penetrate established biofilm to kill the bacteria hiding inside. Hydro Dioxide works entirely differently as an oxidizing gas, actively stripping away the biofilm layer that salt-generated chlorine leaves behind — with a very long lifetime in its sachet.

Active chlorine highly depends on your pool's pH level to be effective and reacts with sweat and oils to form chloramines, which cause red eyes and strong chemical smells. Hydro Dioxide is completely effective across a very wide pH range (from 4 to 10) and does not form any irritating chloramines. It cleans your pipes and surfaces while keeping the water perfectly comfortable for swimmers.

Bromine is often used in warm water like spas because it remains more stable than chlorine at high temperatures. However, bromine is still a halogen sanitizer that lacks the specific chemical action needed to dismantle the tough, protective matrix of a mature biofilm. Hydro Dioxide provides superior stability in warm water while actively eradicating the biofilm structure that bromine cannot break down.

Hydrogen peroxide is an oxygen-based treatment that is gentle on the skin, but it is a relatively weak sanitizer at standard pool concentrations. It breaks down very quickly in the water and is completely ineffective at penetrating and destroying a biofilm colony. Hydro Dioxide offers the same gentle swimming experience but packs the necessary oxidizing power to eliminate severe bacterial contamination and Legionella.

Potassium monopersulfate (KMPS) is an excellent non-chlorine shock used to burn off organic waste and clear cloudy water. However, KMPS is solely an oxidizer, not a standalone EPA-registered sanitiser, meaning it cannot kill bacteria or Legionella on its own. Hydro Dioxide acts as both a powerful oxidizer and a lethal sanitizer, making it a complete solution for deep cleaning hidden plumbing lines.
