Aquarium fish tanks are rising in popularity. With many different types of fish in one aquarium, most hobbyists make a point to introduce variety in aquarium care, including aquarium plants.

Seagrass and macroalgae are often overlooked because they are more difficult to spot than most aquatic plants. But if you want your fish to thrive, you should consider adding some of either.

Read on to learn the effects of including these plants in your fish tank care.

Improves Water Quality

Seagrass filters out particulates and chemicals from water. Macroalgae consume nitrates and other nutrients.

It helps to remove carbon dioxide and other pollutants from the water. These plant species help to create a more balanced and healthy ecosystem for fish and other aquatic creatures.

Habitat and Food for Marine Animals

Most marine animals cannot live in captivity without some type of natural habitat. Seagrass is a type of marine plant that grows in shallow water. It is an important food source for grazing animals such as turtles and fish.

Macroalgae are large algae that grow in both fresh and salt water. They are an important food source for filter-feeding animals such as clams and sponges.

Oxygenate the Water

Through photosynthesis, seagrass and macroalgae help to oxygenate the water. The water in an aquarium with these plants is typically cleaner and healthier than in an aquarium without them.

Add Beauty and Interest to an Aquarium

Seagrasses and macroalgae are two of the most beautiful additions to your aquarium. They come in a wide variety of colors and sizes. Their long, flowing leaves add a peaceful, calming effect to any aquarium.

They can grow to be very large, making them a focal point in the aquarium.  Macroalgae are often brightly colored and can add a vivid, vibrant pop of color to your aquarium.

Negative Effects

While they can have many benefits, they also have negative effects if left unchecked. They can quickly take over an aquarium, crowding out other plants and animals.

To control them, you need to start by keeping your aquarium clean. Regularly vacuum the gravel and remove any debris that has accumulated. This will help to reduce the amount of nutrients in the water that the algae can use to grow.

You need to control the amount of light that your aquarium receives. Algae need light to grow, so by reducing the amount of light, you can help to control its growth.

The Benefits of Seagrass and Macroalgae

If you’re looking to add some extra flair to your aquarium, consider adding seagrass and macroalgae. They add color and texture to your aquarium.

They can also provide some important benefits to the health of your aquatic ecosystem. Be sure to research the proper care requirements to ensure a long and healthy life for your new additions.
