Biox Aqua Water Treatment Tablets are based on the powerful Chlorine Dioxide water treatment biocide - more effective than chlorine or iodine tablets, and it doesn't leave a bad taste or colour the water. Biox is particularly effective against tough contaminants such as Cryptosporidium and Giardia.
To use - add one Biox Aqua Water Treatment Tablet to 1 litre of water and leave to stand for at least 10 minutes. Each packet contains 30 tablets - sufficient for treating about 30 litres of water in total.
Contains: Sodium Chlorite (Active Chlorine Dioxide Precursor), Sodium Dichloro Isocyanurate, Sodium Bi Sulphate, Calcium Chloride
