How to Separate Algae From Water

Algae are simple plants that grow in bodies of water. They range in size from microscopic one-celled algae to seaweed growing 200 feet long. Algae are at the base of the food chain. They provide food and oxygen for other aquatic life that will, in turn, become food for other living creatures. Algae in aquariums and small ponds do not need to be removed unless they are out of control. Algae overgrowth indicates poor quality or stagnant water, improper lighting conditions or too large a population of fish.

Instructions

- 1
  Add algae-eating snails, such as ramshorn, to remove algae from the sides of aquariums. Some fish, such as the Chinese algae eater and the Chinese high fin shark also eat algae. Ascertain which varieties will be compatible in your aquarium or small pond.
- 2
  Wipe the sides of an aquarium or pond liner with a non-scratch scouring pad on a long handle, but not more than once a week to avoid stressing the fish. Do not use household scrub pads. Wipe the aquarium or pond liner immediately prior to changing the water. The filter can clean up any remaining algae floating in the water.
- 3
  Change 10 to 15 percent of the aquarium's water weekly. This step cuts down on free-floating algae and substances in the water that encourage algae growth.
- 4
  Add living plants to the aquarium or pond. These can "starve" the algae because they use the nutrients in the water more effectively than algae.
- 5
  Soak gravel, fake plants, rocks and other items from the aquarium or small pond for a half-hour in hot water, combined with 1/4-cup salt. Remove the items and transfer them to fresh, cool water. Use a brush or your hand to clean any remaining algae. Rinse well. Do not use this method with live plants.
- 6
  Use an algacide, if all else fails. Follow manufacturer's directions. Frequent use of algacides can kill fish.
