Kusuri PRO-100 500ml

Probably the most powerful bacterial aid ever produced for fish keepers.
A number of dangerous pathogenic strains of bacteria like Aeromonas, Pseudomonas, E. coli, can cause catastrophic fish losses in ponds. This has created a strong demand for an effective preventive treatment that does not involve antibiotics, disinfectants, or any other sort of chemical product.
Kusuri Pro-100 is a preventive treatment that does not kill pathogens directly; it helps prevent and restrict their growth. Fish will turn off their immune system if poor quality persists, this encourages the pathogenic bacteria to proliferate and overwhelm the fish and pond. In simple terms Kusuri Pro-100 out competes pathogenic bacteria by consuming its food source.
