Hydrogen peroxide is a strong disinfectant and cleaning agent in bleach products. It will kill any pathogenic organisms living in your water, making it ideal for hydroponics. Although it evaporates within 24 hours, maintenance use will help control pests in the water.
Use for sterilisation of tools and equipment to ensure they are germ-free.
Use at 2ml per litre of water. Can be added up to four times a week.
