Exhales Oxygen: Dwarf Hair Grass is a popular plant for aquariums because it provides several benefits for both fish and other aquatic plants. Like other aquatic plants, Dwarf Hair Grass exhales oxygen which the fish need.  

During photosynthesis, the plant cells use sunlight to convert carbon dioxide into oxygen. The oxygen is then released into the water, where it is used by the fish. In addition to providing oxygen, dwarf hair grass also helps to keep the water clean by absorbing excess nutrients.

As a result, dwarf hair grass is an important part of a healthy aquatic ecosystem.

Absorbs Carbon-dioxide: As anyone who has kept fish as pets know, they require a carefully balanced environment to thrive. One of the most important factors is the level of dissolved oxygen in the water.

Fish breathe oxygen, and if the level gets too low, they will suffocate. That’s where dwarf hair grass comes in. This plant is unique in its ability to absorb large amounts of carbon dioxide and release oxygen.

As a result, it can help to raise the dissolved oxygen levels in a body of water, making it more hospitable for fish.

Substrate: Dwarf hair grass is a popular choice for many aquariums because of its lush look and its relatively easy care. This grass grows best in a rich substrate that provides nutrients and allows the roots to spread.

How To Plant Dwarf Hair Grass? What Should You Know?

Soft Sandy Substrate: The first thing you need to know about planting dwarf hair grass is that you need a soft, sandy substrate. This is because the roots of the plant are delicate and can easily be damaged.

In addition, a firm substrate will help the plant to anchor itself in place. 

Depth: The substrate must have a depth of a minimum of one inch. This helps the roots flex without breaking, which is important for the health of the plant.

Without sufficient root space, the plant will quickly die or have stunted growth.

Soil: Although soil is not strictly necessary for this plant, adding a layer of nutrient-rich soil will render a great benefit. 

It will aid the growth and provide fertility. If you are interested in adding a layer of soil to your aquarium, be sure to choose a type that is safe for use in aquaria.

Placement: Planting dwarf hair grass in an aquarium can create a stunning carpet of green, but it does require some careful planning.

Split the grass bunch into small clumps and plant them two inches apart. Over time, the gaps will get covered.

Some recommend box-shape planting which will ensure even growth. Box shape planting involves inserting the grass in four corners like a square with one in the center. But this is dependent on your layout.

Rooting: When planting dwarf hair grass, it’s important to ensure that the roots go below the substrate and the grass stays above. This can be a bit tricky, but it’s essential for ensuring that the grass grows properly.

Once the grass is in place, you can simply sit back and enjoy the natural beauty of your aquarium.

Aesthetics: When it comes to planting, from an aesthetic perspective, it’s generally a good idea to plant the taller grasses at the back of the tank and the shorter ones in the front.

This ensures that all of the plants are visible and creates a more pleasing overall appearance. 

Trimming: After a few days of planting, trimming is necessary. This has to be done carefully, as you don’t want to damage the roots.

  • Trimming the grass promotes horizontal growth of the grass, which is when the carpet begins to form.
  • Once the trimming is over, scoop off the grass with a net to protect your filters. With a little patience and care, you’ll be rewarded with a beautiful set-up that looks like something straight out of a magazine!
  • If you trim it before planting, the grass will grow slowly. Strangely, when trimmed after planting they grow horizontally and quickly.
  • If you want thick growth in a particular place, just plant them together without separating them.

Answers To Some Common Problems

ezgif.com gif maker 2022 06 28T121428.294
  • Melting leaves: Pluck off the bad parts and you will soon find new bits growing. It could also be due to the water conditions and it would be wise to check your water parameters.
  • The grass is not carpeting the floor: this means that there is a lack of light either in terms of the time of exposure or in terms of the strength of the light. Increase light exposure. The other thing you should check is the nutrition. Try adding a liquid fertilizer and trim the grass a bit.
  • Getting uprooted: this problem is usually due to the strong filter or currents in the water. Ensure that this is solved and you will soon see good growth and the roots binding themselves to the substrate.
  • Holes On The Leaves / Broken Leaves: This could happen if you have the wrong types of fish or snails in the aquarium who are capable of damaging the grass. Take time to identify them and separate them.
  • Growing Too Slow: There are two reasons for the grass to grow slow. Either they are planted too closely and crowded and the nutrition is insufficient. In the case of crowding trimming and removal of some grass would help. And in the case of lack of nutrition adding a liquid fertilizer would help.
  • Blades Turning Yellow: This shows a lack of light, nitrogen, phosphorus, and potassium. Increasing light exposure and adding specific nutrients should solve the problem.
  • Blades Are Breaking: This is purely a problem where the light is insufficient and the only solution is to increase the light.
  • Not Rooting: If the substrate is too thick and does not permit the grass to go through the substrate. Under the circumstances adding a layer of sandy substrate on top could help. However, this has to be done very slowly and carefully.

Wrapping Up:

Dwarf hair grass is a great choice for an easy-to-care aquatic plant. By following this guide, you will have a lush green carpet and a healthy ecosystem in your tank. Not only will your plants be happy, but your fish will love the extra bit of cover too!

It will help purify the water in your tank and add beauty to your tank. With a little light, nutrition, and substrate, they will do fairly well on their own and can even self-propagate.
