Healthy fish stocks need healthy water. PeriDox improves the level of hygiene in fish ponds and fish farms simply and safely by preventing the proliferation and spreading of parasites and algae. This is achieved by a natural oxidation process that destroys the cell structure of floating parasites or their blooming stages. Depending on the temperature of the water, parasites that would otherwise have survived for 48 hours in the water are killed in 3 hours. PeriDox should be used 3 to 4 times to remove the adult parasites that may still be active. Since this treatment also causes oxygen to be released, PeriDox can be used if the water contains an insufficient amount of oxygen.
