About this product
AqueousPro™ Rainwater Tanks is a food grade water sanitiser designed to treat rainwater and freshwater holding tanks, helping reduce bacteria and waterborne viruses and keep your stored water clean and ready to use.
The 5L size is ideal for treating larger volumes of tank water or for customers who require ongoing water treatment. AqueousPro™ can be added directly to your tank, providing a simple and convenient way to maintain the quality of your stored water.
For best results, tank water should be relatively clear of organic material. Poor quality water may require higher dosage levels depending on the condition of the water.
Use AqueousPro™ Test Strips 24 hours after treatment to check the effectiveness of the treatment and confirm the appropriate level has been achieved.
