How to Get Rid of Farm Pond Algae Growth
Pond algae is a common problem in farm ponds. Algae detracts from the appearance of the pond and, if there is enough of it, can kill native pond plants by blocking sunlight. Too much algae also can kill your fish by interfering with healthy oxygenation of the water. While it will not be possible to remove every piece of algae, you can significantly reduce it to a manageable level. Once reduced, you must maintain the pond properly to keep algae at bay.
Remove organic, decaying matter from your pond. Rake out old leaves from the bottom of the pond and skim organic matter from the surface.
Feed fish at certain times during the day. They will grow accustomed to feeding times which prevents fish food from collecting at the bottom of the pond. Stop feeding them if they cannot eat the food within three minutes.
Pour a pond dye in your pond. Follow the manufacturer's instructions for the specific dye you use. The pond dye will reduce sunlight in your pond, which will slow algae growth.
Add beneficial bacteria to your pond at a rate of 12 lbs. per surface acre. Add 6 lbs. every two weeks thereafter for the duration of the summer.
Aerate your pond with a pond aerator. A pond aerator will introduce oxygen to the water and mix it up. This will reduce the anaerobic bacteria (bad bacteria that do not require oxygen and help algae flourish). It will also increase oxygen levels which allows your beneficial bacteria and fish to thrive.
Things You Will Need
- Pond rake
- Pond dye
- Beneficial bacteria
- Pond aerator
- Consider installing a pond net on your pond. A pond net will prevent leaves and other organic matter from falling into the water. It will also prevent predatory birds from eating your valuable fish.
