The aquarium is a place where the family can watch and relax. However, if your fish tank grows moss, it will lose its landscape and aesthetics. So what causes fish tanks to grow moss? If you use fish tank moss killer, will it affect the creatures in the tank? To find the correct answer, follow the article below! Duc Binh Microbial Products shares details about: Some notes when using tank moss killer fish

1. Harmful effects of moss in aquariums when overgrown

A fish tank is considered a beautiful decorative feature in every family and is also a joy to help the family relax. However, many fish farmers often encounter the extremely painful problem of green moss. Having a fish tank dominated by green moss not only simply affects the aesthetics of the tank but also causes many consequences such as:

  • Loss of aesthetics: The first and most obvious harmful effect is the loss of aesthetics of the fish tank. The fish tank is covered with a layer of moss that looks very dirty, obscuring the viewer’s view.
  • Compete with aquatic plants for nutrients: Green and black moss will absorb all the nutrients that aquatic plants need in the tank. This causes the tree to grow slowly, stunted or even die.
  • Reducing oxygen in water: Moss and algae also breathe at night, reducing oxygen in the water. If the amount of moss produced is too large, it can cause the tank to lack oxygen, causing suffocation for fish and other creatures.
  • Causing stress to fish: Moss clinging to the fish’s head causes an imbalance in the water environment, causing the fish to become stressed, susceptible to disease or even die. 
  • Changes pH: Some types of moss can cause the water in the tank to change the pH, affecting the health of corals and fish.
  • Equipment blockage: Moss can stick to pipes, filters, and heaters, significantly reducing the performance of the equipment. This requires farmers to clean more frequently.

2. What causes fish tanks to grow moss?

A fish tank with green moss is a common case in families raising ornamental fish. This problem not only destroys the beauty of the aquarium but also affects the quality of fish health development.

So what is the reason why the fish tank has green moss? Find out the reasons to ensure the fish tank is always clean and moss-free. Below are some reasons why your aquarium has green moss:

Excess light

Many homes will not know that shining light 24/7 is the main cause that causes moss to grow quickly. Shining light will make the fish tank more beautiful, gorgeous, sparkling and also make the house cozy.

Excess light is also the cause of green moss in the aquarium

Excess light is also the cause of green moss in the aquarium

However, this accidentally causes your aquarium to grow green moss because moss extremely likes light. Therefore, use lights reasonably and properly to protect the beauty and health of the creatures in the tank. Besides, if it’s not necessary, you don’t need to use lights.

Excess phosphate and nitrate

Phosphate and nitrate are two nutrients that moss and harmful algae absolutely love. Nitrate can be produced from fish feces or leftover food. One piece of advice for you to keep your tank clean is to keep fish in sufficient quantity.

Depending on the size of the tank, raise fish in appropriate quantities. Raising too many fish also makes it impossible to control the quality of water used to raise fish. Besides, it also makes green moss grow more. In addition, you should not feed the fish too much because the fish’s leftover food will produce nitrates. Feed your fish at a reasonable time, 1-2 times a day and only eat for 5 minutes! Furthermore, make sure that the fish food source is purchased from a reputable place with a clear origin to avoid causing fish diseases.

No filter system

Before buying a tank and raising fish, make sure there is a water filtration system. Prioritize filters with optimal filtering function to help push harmful substances out. At the same time, it will also improve the water environment to be cleaner.

Less cleaning and adding water to the fish tank

When raising fish, many people will think that just feeding the fish enough will make the fish grow well. But you don’t know that water quality also affects fish. If you don’t change or wash the fish tank for a long time, it will make the water cloudy and promote strong growth of algae and moss spores. So be careful to change the water at least once a week to keep the water clear. However, look for clean water sources that are low in toxic substances. If you change the water regularly but the water source is not guaranteed, it will still not improve the moss situation

If you find the previous method fast but don’t see good results, you can switch to another method. With this method, dilute the medicine in a 1:1 ratio. When finished mixing, use a syringe to spray the mixed solution on the area with moss and after 2 hours, turn the filter back on normally.

This way you will see the moss gradually turn purple and white. And repeat for the next 2 days when the moss has died and changed color, it will decompose itself in the next 3 days. While using fish tank moss killer, it is not necessary to change the tank water. If you are careful, you can repeat the cycle like the first time to ensure that harmful moss and algae will not grow.

Notes during use

For the process to proceed properly and not affect the quality of fish in the tank, please follow the following notes:

  • If the tank has not changed the water for too long, drain 30% of the water before using fish tank moss killer to increase effectiveness.
  • Turn off the CO2 system or reduce CO2 to a minimum
  • When using, leave the medicine exposed to light for better effectiveness
  • Store the medicine at room temperature and avoid direct sunlight to prevent its effectiveness from being reduced. Shelf life is about 2 years.

Just like other fish tank moss killers, the method is completely similar. You should change ⅓ of the water in the tank and then dilute the solution. Then use a syringe to spray the moss on the area and wait for the color to change and the moss will decompose on its own. You should light it every day for about 1 week – 15 days to ensure that the moss is clean and completely removed.

Algae killer with hydrogen peroxide

This is a method that is not used by many people despite its low price. Because for tanks with fish and not much moss, you should only use fish tank moss killer.

For tanks and lakes with heavy green moss, this method is needed. Because the fish’s environment needs to be balanced in terms of light, nutrients and CO2 and limit the use of chemicals. Because using chemical drugs comes with many great risks, everyone should be careful before using them.

First you have to turn off the filter, fan, CO2 and then take 1 to 1.5ml of hydrogen peroxide for every 1 liter of aquarium. Then use a syringe to pump up areas where moss has been clinging for a long time, wait 5 minutes and then turn on the filter at full capacity. Turning on full power will allow the flow to carry hydrogen peroxide to the entire tank within 15 minutes.

Once done, don’t change the water for 1-2 days and observe to see if the moss is clean or completely gone. Most people using fish tank moss killer with hydrogen peroxide in lakes and tanks will see immediate results, but you should also observe and pay attention to the behavior of fish and plants in the tank.

4. How to limit the appearance of green moss in the aquarium

Reducing green moss in an aquarium is not too difficult. But you must know how to limit and eliminate this situation. Below is a way to limit green moss:

  • Changing water properly: not having to change water frequently is good. Because fish will always have to adapt again if the water environment changes too much. Therefore, you should only change the water for fish about once a week. However, you should not remove the old water but should keep 30% of the water in the tank.
  • Clean the tank regularly: always keep the fish tank in a clean condition. A dirty fish tank will cause the formation and growth of harmful moss. This reduces the beauty of aquatic life in the tank.
  • Regularly use microbial products to treat aquarium water EMZEO or EMKOI
