Key Questions to Ask When Ordering Stabilised Chlorine Dioxide

As part of the EPA registration process, disinfectant products are put through rigorous testing to prove their efficacy and measure toxicity. The EPA registers three types of disinfectants: Limited, General, and Hospital. All three disinfectants destroy or irreversibly inactivate certain microorganisms on hard, inanimate surfaces and objects. You can determine a “limited,” “general,” or “hospital” disinfectant by the microorganisms listed on the label.

Limited must be supported by efficacy testing against either Salmonella cholerasuis or Staphylococcus aureus. Limited disinfectants are found mostly in household use.

General must be supported by efficacy testing against both Salmonella cholerasuis and Staphylococcus aureus. General disinfectants are used in commercial areas.

Hospital must be supported by AOAC Use Dilution or AOAC Germicidal Spray efficacy testing against Staphylococcus aureus, Salmonella cholerasuis and Pseudomonas aeruginosa. The bacteria Pseudomonas aeruginosa hides behind biofilm and is difficult to eliminate. Killing this bacterium is required for “Hospital Disinfectant”.

It Is absolutely safe to add ClO2 into your potable water tank as long as you follow our directions for use.

NZ regulations for potable water recommend that you not exceed 0.8ppm of Chlorine Dioxide in your potable water.
We recommend 50-550ml of DX50 Water Treatment to Ltr of water depends on the quality of the water. Usually 50ml will just be enough to kill all of the bad bugs.

We encourage our clients to have their water tested to better understand the quality and bacterial loading.

Yes, it is safe for use in animal troughs. However, as DX50 breaks down in sunlight, dose the troughs when it gets dark. For more effective results, remove as much organic material in the trough as possible before dosing. Once a measured dose is applied according to instructions, DX50 will effectively sanitise the trough water without harming your animals.

Yes, DX50 Chlorine Dioxide can be used in fishponds for disinfecting water and controlling algae and bacteria. However, it's crucial to use it carefully because it can be harmful to fish and other aquatic life if not dosed correctly. The typical recommended dosage of chlorine dioxide in fishponds is between 0.05 (33ml of DX50 per 100Ltr of water) to 0.1 (66ml of DX50 per 100Ltr of water) parts per million (ppm). It’s advised to dose it regularly without exceeding the ppm limits mentioned above.

This is a common question we receive. Typically, for the average household, we recommend treating your tank water with DX50 once a month during warmer months and every two months during cooler periods.

However, there are many variables when it comes to treating water supplies, so please refer to our article "How Often Should I Treat My Water Tank?" to understand some of the challenges you may encounter.

The amount required depends on the size of the tank and the level of contamination. The recommended dosage is 0.05ml per litre of water (or 50ml per litres of water). So, for example, if you have a 30,000L tank you’ll need to apply ml of DX50 (30,000L x 0.05ml = ml). If your tank is half full, adjust the dose accordingly (15,000L x 0.05ml = 750ml).

To better understand the quality and bacterial loading make sure you have your water tested before and after dosing. If tests confirm that your water is heavily contaminated, know that you can safely dose your tank with up to x10 the recommended dose and still meet NZ potable water guidelines. (550ml of DX50 Water Treatment per L of water.

After adding 50 mL of DX50 per litres of water, the ClO2 concentration in your treated water will be approximately 0.075 ppm. This concentration is well below both New Zealand’s and the EPA’s maximum limit of 0.8 mg/L (or ppm) for chlorine dioxide in drinking water, ensuring both effective treatment and compliance with regulatory safety standards. Note that milligrams per litre (mg/L) is equivalent to parts per million (ppm).

Yes, DX50 Chlorine Dioxide Sanitiser is also highly effective at killing a wide range of mould and fungus species. It works by disrupting the cellular processes of these microorganisms, which typically results in their death. However, the effectiveness can vary depending on factors such as the concentration of DX50 used, contact time, and the type of surface being treated. If you are using DX50 for this purpose, we recommend that you clean all visible mould before applying a dilution of DX50 to enhance penetration and effectiveness. For severe infestations you may require multiple treatments. You can safely tackle your mould or fungal problem with a ratio of 40:1. Addressing moisture and ventilation is key to preventing mould recurrence post-treatment.

DX50 has a strong odour in its concentrate form and care should be taken not to inhale when decanting. It is recommended to use it in a well-ventilated area. If you inhale enough to feel unwell, find and breathe fresh air. If you don’t feel better after a short while, seek medical advice.
