Java moss turning brown indicates a serious problem in the environment of your aquarium. Java moss is a highly resistant plant and doesn’t allow minor environmental changes to affect it. It can tolerate extreme heat and cold conditions so, if you see your java moss turning brown, you must find out the reason. To make it easier for you, here we have listed all the possible reasons that can make your java moss brown.
Why Is My Java Moss Turning Brown?
The most common reasons for the browning of java moss are mentioned below:
Excess of Algae
Algae are the non-flowering and aquatic organisms that resemble plants in many ways. The favorite habitat of algae is water, especially uncleaned with unhygienic conditions and excessive sunlight. In some cases, algae are considered beneficial, but mostly they are harmful to the aquarium environment.
When a lot of sunlight is available, algae start growing on the surface of java moss. As algae expand in water, it consumes most of the essential minerals from it. With time, the mineral levels are decreased to the extent where no minerals are left for the growth of java moss. When this happens, your java moss, being deprived of nutrients, starts turning brown.
Insufficient Nutrient Absorption
The health problems in java moss and the excess of algae can decrease your java moss’s ability to absorb nutrients. When the algae occupy java moss, the latter becomes incapable of producing food using light energy. Due to the decrease in nutrient levels in java moss, it starts becoming brown as it absorbs and produces insufficient nutrients.
Lower Carbon Levels
Like all plants, carbon dioxide is an essential gas for the survival of java moss. It uses carbon dioxide for photosynthesis like other green plants to produce food in the form of carbohydrates.
Due to some conditions, the levels of carbon dioxide may drop in your aquarium. As a result, the rate of photosynthesis and consequently the amount of carbohydrates also decreases. Carbohydrates are important for healthy java moss.
The situation becomes even more complicated with the growth of algae. It competes with java moss for the nutrients available in the aquarium. The absence of photosynthesis and the presence of algae leads to the starvation of java moss. This starvation may cause the death of java moss.
As we saw, a java moss dying may first become brown.
Java moss doesn’t only look good in your aquarium but also has excellent cleaning properties. It can pick the debris by accumulating it over its surface and inside. Hence, it’s a great addition to your aquarium if you want to keep it clean.
It can help you get rid of both the debris as well as the fish leftover food. Hence, when your java moss consumes these food particles and the debris, that makes it brown at various spots.
Low light levels can stop or decrease photosynthesis for your java moss. When photosynthesis decreases, the essential nutrients required by the plants are also decreased. In the absence of these nutrients, java moss starts becoming brown. The absence of food affects the health of the plant, and it starts decaying.
Poor Fish Tank Maintenance
You should be surprised if you see your java moss turning brown when your aquarium isn’t clean. The dirty water promotes algal growth, which can affect the growth of java moss. Moreover, dirty water also harbors many harmful bacteria that can affect the health of java moss. So, it’s crucial to keep your fish tank clean to avoid this situation.
Sometimes the reason for your java moss turning brown is the plant itself. Excessive growth blocks the sunlight and nutrients from reaching the middle of the plant. Due to the decrease in absorption of both light and nutrients, photosynthesis decreases too.
As a result, your java moss turns brown with time. To avoid this scenario, it’s essential to prune your java moss as required.
Can a Brown Java Moss Turn Green Again?
The duration for healing of the java moss varies depending upon the extent of browning. The more it has turned brown, the more time it will need to become green again under suitable nutrients and lighting conditions.
How To Treat a Brown Java Moss Plant
Here are some things that you can do to treat a brown or dead java moss:
Check Algal Growth
Removing algae from your fish tank is the primary step to bringing your java moss ball turning brown back to life. When there is no more competition for nutrients, your java moss can flourish again.
In the absence of algae, your java moss will be able to get more light for photosynthesis. When the rate of photosynthesis increases, the brown portions of java moss start disappearing. To remove the algae, you can use pressure water wash or specialized cleaning equipment.
Limit the Use of Fertilizer
Like all plants, java moss needs plant fertilizer for growth. However, you must remember that excess of anything does more harm than good. If your java moss gets too much fertilizer, it can lead to the growth of thick leaves.
These thick leaves will not absorb sufficient nutrients. Hence, your java moss will turn brown if you feed it too much fertilizer.
Supply Required Carbon Dioxide
Your fishes in the tank naturally release carbon dioxide while breathing. However, sometimes the carbon dioxide levels can drop significantly in your aquarium. In such cases, you must supply carbon dioxide from outside to avoid the browning of your java moss.
A good source of carbon dioxide for java moss in the aquarium is excel. It’s available in liquid form and can be easily added to the fish tank. But you must use it as per the manufacturer’s instructions because too much carbon is also harmful.
Frequently Check Aquarium’s Water Quality
It’s crucial to check your aquarium’s water quality frequently to keep your java moss green. If the water isn’t clean, algae can grow and block the supply of nutrients to your java moss. It’s often recommended to change almost 25 percent of your fish tank water every 15 days. It helps to remove the contaminants from the water and provides sufficient oxygen and nutrients in there too.
Use a Filter To Keep Your Fish Tank Clean
It’s both a preventive measure as well as a treatment for brown java moss. Use a filter to get rid of the bacteria and waste products that can build up on the surface of java moss. The filter absorbs these bacteria and waste substances before they make space over the leaves of java moss.
To ensure that your filter is working properly, clean it every 15 days, as some substances might be in there and it’s important to remove them from the filter.
Is Brown Java Moss Dying?
Yes, brown java moss is a sign that it’s dying. Java moss becomes brown when it doesn’t get sufficient nutrients, light, or clean water. All these things are necessary for its survival. In the absence of these, your java moss will first turn brown and eventually die if not treated on time.
Can a Brown Java Moss Lead To Aquarium Plants Browning?
Yes, brown java moss can lead to aquarium plants browning. The browning of java moss doesn’t have a direct effect on the growth of other plants. However, as your java moss dies, the decayed plant is mixed with water. As a result, the water of the tank becomes impure.
Other plants’ growth becomes limited in the presence of waste products. Their photosynthesis stops, due to which they start dying. The dying plants first turn brown.
Is Dead Java Moss Harmful to the Fish?
Yes, dead java moss is harmful to the fish. When the java moss dies, it releases waste products into the water. These waste products are consumed by the fishes and reach their organs.
As a result, the health of your fish is compromised, and they can even die. Hence, to keep your fish safe, removing the dead java moss from the aquarium is better.
Is Dead Java Moss Harmful To Other Plants?
Yes, dead java moss is harmful to other plants. In addition to aquarium plants turning brown, dead java moss can create many other health problems too. It starts a chemical reaction in the water tank, which is harmful to plants’ health in the aquarium.
As you have learned everything about java moss turning brown, let’s quickly revise all the important points:
- A java moss turning brown indicates it’s dying due to the deficiency of nutrients and absence of photosynthesis
- The primary reason for brown java moss is the excess of algae in the fish tank
- Other things that can cause the browning of java moss include low light and carbon levels, insufficient nutrients, dirty tank water, and inadequate pruning
- Dead java moss is harmful to other plants and fish
- To make your brown java moss green again, you should first remove algae from the tank. Then, ensure sufficient nutrients, light, carbon, and cleaning of water
With these simple measures, you can bring your dead java moss back to life. It’s important to continue the treatment until your java moss has fully recovered and has become green again!
