Giardia is a microscopic parasite found worldwide. The parasite can cause a diarrheal disease in humans and animals. According to the Centers for Disease Control, once a person or animal is infected with giardia, the parasite lives in the intestines of its host and is passed in the feces. Once passed by the infected person or animal, giardia can live outside of the body for weeks and even months. Untreated or improperly treated water supplies can harbor the disease. Super-chlorination is the safest and most effective method to remove giardia from a water supply.
Things You'll Need
- Large measuring cup
- 5 percent liquid chlorine solution
- Safety goggles
Super-Chlorinating A Fish Pond
Remove all fish, plants and other organisms from the infected pond and destroy. This ensures the Giardia parasite will not be reintroduced after the pond water is disinfected.
Measure out 6 cups of 5 percent chlorine solution per 100 gallons of water requiring treatment
Pour chlorine solution into pond and allow to sit for at least 24 hours
Wait at least 24 to 48 hours for chlorine levels in the pond to drop to zero. After this waiting period, introduce new plants and fish into the treated pond.
Tips & Warnings
- Chlorine will irritate your skin, eyes and respiratory system. Wear gloves and safety goggles when handling the chemical. Chlorine will also burn and kill all aquatic life in your pond. Wash hands thoroughly after coming in contact with anything that could be infected with giardia.
