How to Stop Algae Growth

Stop Feeding Algae.

• 1

  Follow the instructions that come with your fish food. Feeding your fish too much, will result in phosphates and nitrogen compounds in the water. This helps algae grow.

• 2

  Take out as much of the feed water as you can, before adding more food.

• 3

  Rinse your hands thoroughly before coming into contact with the water of the aquarium, as soaps also have phosphates.

Lessen Light in the Aquarium

• 4

  Move your tank away from windows. Too much natural sunlight boosts algae growth.

• 5

  Create more shade for the tank. Closing your curtains for longer periods, is one way to achieve this.

• 6

  Leave the aquarium lights on for 6 to 8 hours each day, if your tank only consists of fish.

Pond Solutions

• 7

  Add floating pond plants, such as Anarchris, if your algae problem is in your pond. These absorb nutrients from the water, which stops the growth of algae.

• 8

  Cover 50 percent of your pond's surface with floating pond plants. These will not only absorb a lot of nutrients, but block sunlight from entering the water.

• 9

  Plant some evergreen underwater plants. These naturally clean the water and add oxygen, stunting algae growth.

• 10

  Use gravel as a base for your pond plants. Using soil will provide algae with the conditions they need to grow.

• 11

  Introduce snails and tadpoles to your pond. They will eat algae.

Manually Clean Pond

• 12

  Clean your pond in the autumn.

• 13

  Remove dead foliage from the base of the pond. By the time summer arrives, this rotten vegetation will become nutrition for the algae.

• 14

  Use a pond net or a pond vacuum to make sure you have cleaned the pond thoroughly.
