How to Get Rid of Mold on Elodea Plant

Updated: April 2, 2023

Elodea plants are a great addition to any aquarium or pond, providing oxygen and helping to keep the water clean. However, like any plant, they can be susceptible to mold growth. Mold not only looks unsightly but can also harm the health of your aquatic ecosystem. In this article, we will discuss how to get rid of mold on elodea plants and prevent its return.

Identify the Type of Mold

Before taking any action, it is important to identify the type of mold growing on your elodea plant. There are several types of mold that can grow on aquatic plants, including green algae, black algae, and white fungus. Each type requires a different approach to eliminate it.

  • Green Algae: This is a common type of mold that grows on elodea plants. It appears as a green film on the leaves and stem of the plant.
  • Black Algae: This type of mold is less common but can still occur on elodea plants. It appears as black spots on the leaves and stem.
  • White Fungus: This type of mold appears as a white cottony substance on the leaves and stem.

Once you have identified the type of mold growing on your elodea plant, you can take appropriate action to eliminate it.

Remove the Affected Leaves and Stems

The first step in getting rid of mold on elodea plant is to remove the affected leaves and stems. Use a pair of scissors or pruning shears to carefully cut away any parts of the plant that show signs of mold growth. Be sure to dispose of these parts properly to prevent further contamination.

Adjust Water Conditions

Mold thrives in warm, stagnant water with high levels of nutrients. To prevent its return, you need to adjust the water conditions in your aquarium or pond. Here are some steps you can take:

  • Increase water flow: Use a filter or water pump to increase water circulation in your aquarium or pond. This will help to prevent stagnant areas where mold can grow.
  • Reduce nutrient levels: Overfeeding fish or adding too much fertilizer can lead to an excess of nutrients in the water, which can promote mold growth. Be sure to follow recommended feeding and fertilizing guidelines.
  • Control temperature: Mold thrives in warm, humid environments. Try to maintain a water temperature of 68-72°F (20-22°C) to discourage mold growth.

Use Chemical Treatments

In some cases, removing the affected parts of the plant and adjusting water conditions may not be enough to eliminate mold growth. In these cases, you may need to use chemical treatments. Here are some options:

  • Hydrogen peroxide: This is a common treatment for green algae. Add 1-2 milliliters of 3% hydrogen peroxide per gallon of water. Be sure to turn off any filters or pumps before adding the hydrogen peroxide, as it can harm beneficial bacteria.
  • Algaecides: These are chemical treatments specifically designed to eliminate algae and other aquatic plant molds. Be sure to follow the instructions carefully and use only as directed.
