About this product
AqueousPro™ Marine is a food grade water sanitiser designed for marine and boat water tanks, helping reduce bacteria and waterborne viruses and keep your stored water clean and ready to use while out on the water.
The 5L size is ideal for larger onboard water tanks, regular boat users or those who simply want a larger supply on hand. It provides a simple and convenient solution for maintaining the quality of stored water on boats and other marine vessels.
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.
