Green plaque on the walls of a home aquarium, how to get rid of it: mechanical and biological methods

One of the most frequent issues that many aquarium owners deal with is green plaque on the walls of their homes. In addition to detracting from the tank’s aesthetic appeal, it may harm the aquatic ecosystem as a whole. Algal growth, which is favored by circumstances such as an abundance of light, low water quality, or nutrient accumulation, is typically the source of the greenish film.

Thankfully, there are practical solutions available to address this issue and maintain the bright, tidy appearance of your aquarium. You can employ a variety of techniques, from straightforward mechanical ones like scraping off the algae to organic biological ones like enlisting specific species of fish or snails. Every approach has advantages, and you can select the one that best suits your aquarium’s requirements.

You can prevent green plaque from developing in your aquarium and provide your fish with a healthy and visually pleasing home by learning about the causes and looking into both mechanical and biological solutions. Now let’s explore the most effective ways to get rid of algae and keep the water clear.

Why algae grow in an aquarium

In an aquarium, algae can grow for a variety of reasons. Let’s examine the causes of this and possible solutions to prevent harm to the algae:

• If several types of different plants are already settled in your aquarium, the algae will simply exist, but there can be no talk of growth in this case.
• It is extremely important to check that the water has sufficient aeration. Due to the high oxygen content in the water, you can restrain excessive algae growth.
• In addition to the aerator, it would also be useful to have a filter for aquarium water. In addition to the fact that the filter purifies the water, it also changes it. Due to this, the level of nitrates is significantly reduced, and organic residues are removed.
• The aquarium should be illuminated with devices for no more than 12 hours, and the light should be powerful enough.
• It is also important to observe the number of fish in the aquarium. Otherwise, the creatures will secrete nitrates in such quantities that the algae simply will not cope.
• It is possible to add fish whose favorite food is algae. We are talking, for example, about molly and loricaria.
• Do not forget about regular cleaning, as well as changing the water.
• Feeding should also be in moderation.

A home aquarium’s walls can be effectively cleaned of green plaque by combining mechanical and biological techniques, such as routine glass cleaning, the use of specialized tools, and the introduction of fish or snails that eat algae to help naturally control the buildup.

Reasons for the appearance of green plaque on the walls of the aquarium

Inadequate wall maintenance is the main cause of plaque development, though some types of algae may also contribute to the formation of green plaque. But there are also a lot of other causes for this kind of issue. For instance, this could be the result of feeding the fish too generously or with an improperly adjusted temperature or lighting schedule. There are numerous other explanations as well, which are detailed in the table.

Recall! There isn’t just one reason why algae reproduce. This is most likely a result of multiple factors working together.

Reason	Explanation
Fast-growing plants	In this case, there may be several reasons for the problem: too many plants of this type, or even their complete absence. Also, such plants can generally follow the very same "brake" for growth. In such cases, there is an oversaturation of nutrients, which provoke growth.
There is too little phosphorus, and a lot of nitrogen	With such a ratio of substances in the aquarium, protococcus appears, which is the reason for the greening of the walls in this case.
Location	A common mistake of novice aquarists is to place the aquarium in a place where sunlight falls. It is a mistake to believe that such a vet can be useful for fish, it simply provokes the growth of algae and spoils the water.
Incorrect temperature regime	It is important to consider that each type of fish requires its own temperature regime during maintenance, so you should not buy pets that can exist in different temperatures. Violation of this point can not only provoke the growth of algae, but also lead to poor health in fish.
Irregular care	Few people know that even if you have all the necessary gadgets for caring for an aquarium, you should manually clean it on a regular basis, since uneaten food settles to the bottom, which simply rots later, and waste products also settle in this mass.
High salt content	If you change the water infrequently, as well as if you do not let the water settle before pouring it into the aquarium, the salt content may be too high. In addition, do not forget to change the water after a salt treatment course.

Thermal regime

Making sure the lightbulb aimed towards the aquarium doesn’t heat the water is crucial. Weed growth is triggered by the rising temperature of the water. For aquarists, the warm season presents a different challenge because it is much harder to control the water’s temperature during this time.

Take note! In addition to being much worse at allowing oxygen to pass through, warm water is a great place for nitrates to form, which are the building blocks that plaque-forming algae love.

Lighting mode

The aquarium should be positioned to avoid direct sunlight as this will cause the process of greening the walls to begin much more quickly. The aquarium should receive no more than 12 hours of light in the summer and no more than 7 hours in the winter.

A large amount of food

It’s a myth that fish require a lot of food to survive. Overfeeding pets never produces positive results. Furthermore, the fish won’t be able to consume all of the food if you add too much to the aquarium, and the leftovers will sink to the bottom. After the fish have finished eating, you should remove any leftover food from the bottom if you overindulged.

Waste products

A food remnant and waste product mixture that is caustic creates an ideal environment for the production of ammonia and nitrates. Such contaminants contaminate the water, causing a green film to develop on the glass walls.

What is needed to clean the soil and stains on the glass

You should be aware that thoroughly cleaning the aquarium without the use of specialized equipment is very challenging. In addition, slightly different instruments will be required to remove the dirt and stains from the glass. For instance, you can generally use a regular siphon instead of an aquarium vacuum cleaner to clean the soil and wash the stones. Choosing the cleaner itself should be based on how frequently you intend to clean the aquarium. The most important thing is to keep the water and stone from blooming and developing a green layer.

You also need to bring a scraper to clean the glass. Any pet store will sell a magnetic version that you can buy for convenience. They enable you to prevent scuffs on the walls. Although these are by no means all the equipment needed to properly clean an aquarium, each person’s needs are unique, and for some, a scraper and a siphon are more than sufficient.

How to quickly remove green coating in an aquarium

We have previously determined the cause of the green coating that develops on the aquarium walls, so it is now important to know how to remove it. Green dots on the aquarium walls can actually be removed using multiple techniques at once. Now let’s examine which ones aquarists most frequently recommend.

Mechanical method

This approach is comparable to the biological approach, which is covered in more detail below. There are certain variations in this case, though. Here are some pointers on what not to do at all and the best way to clean the walls:

• You can only reuse the same scraper if it is well disinfected. Otherwise, you can simply bring the same bacteria into the aquarium, which will provoke even more green plaque.
• When cleaning the aquarium, you should protect your hands with gloves.
• If plaque is difficult to wash off, you can use a special blade as an aid.
• Aquarium decorations also often suffer from the appearance of green plaque. In this situation, you should prepare a special solution that will help solve this problem. It consists of the volume of water required to immerse the decoration and a small amount of regular bleach. The element should be placed in the resulting mixture for literally 15 minutes, and then doused with boiling water. This should help to remove plaque much faster.

Biological method

It is safe to say that this approach is the simplest. Given that exercising some patience in this circumstance is the hardest thing to do.

It’s a little-known fact that algae can go extinct entirely in 21 days. New cells won’t grow during this time, and the old ones will progressively start to disappear. In this case, it will be sufficient to just close the aquarium for the duration of that time, and then clean it afterwards.

It is important to realize that the biological method’s mechanics of action will vary slightly between aquariums that are more and less modern. In the event that carbon dioxide is not added to the aquarium, the following actions should be taken:

• Thoroughly clean the aquarium.
• Change the water, but not completely, and renew it only by 30% of the total amount.
• Nothing else should be added. Just leave the aquarium for 21 days.

The water in a high-tech aquarium remains the same, but adding different fertilizers to the water is one of the main distinctions from maintaining a conventional aquarium. It is preferable to lower it by 25% in this instance; you do not need to add the same amount. Cleaning the aquarium should wait until after three weeks. The following are the instructions for execution:

• Move the fish and other inhabitants of the aquarium to some other suitable container.
• Next, take the hardest sponge and clean even the heaviest plaque from the walls of the aquarium and completely drain the water.
• Rinse each element of the decoration thoroughly, and do not forget to loosen the soil. The most important thing is not to forget to go through a special vacuum cleaner, which will remove excess particles.
• Rinse the aquarium from the outside as well, and only after that put back all the remaining decor and soil, and then fill it with water.
• Connect all the equipment and only after you make sure that all the indicators are normal, you should launch the fish.

Special preparations

If you want to quickly restore the aquarium to its original appearance, this method might be ideal. Most of the time, streptomycin is appropriate for these uses. The product requires a small amount of powder added to boiling water in order to function. It’s plenty, about three grams per liter. Instead of immediately pouring the solution into the aquarium, it first passes through a filter. A product like this can produce noticeable results in as little as three days, and in certain situations, even quicker.

Kindly take note! Without fish, streptomycin is completely safe, so there’s no need to move the aquarium’s occupants while it’s being cleaned.

This is by no means your only option, and experts in specialty shops can quickly recommend the best item for your needs.

Furthermore, the products should not be mixed with activated carbon. Moreover, don’t forget to regularly remove dead tissue from your aquarium as this can encourage the growth of new algae and restart the process of greening it.

Creating optimal conditions

Alternately, you could do the exact opposite and put algae in circumstances so unsuitable that they will just start to wither. The aquarium should be taken out of the direct sunlight-exposed area right away. Observe the daylight hours; they ought to be no more than ten hours.

You should only bring cold light lamps to light the aquarium. A pH increase and an approximate temperature of 25 degrees are required for the water.

It is important that you adhere to the directions on the preparations used in order to preserve equilibrium and prevent the phosphorus level from rising above the recommended level. You must move some of the aquarium’s inhabitants to another tank if there are too many of them.

Observe how much food the fish are receiving. Pour out enough so they can finish eating in no more than ten minutes. Along with increasing the aeration, the aquarium filtration must also be strengthened.

Water change

This approach combines multiple approaches at once. First, you must use a scraper to clean the aquarium’s glass, and a siphon to clean the dirt. It is crucial to follow this procedure; if you begin at the bottom, the scraped particles will fall back and clog the aquarium’s bottom.

You ought to replace the water once a week to perform preventative measures. Additionally, only one-third of the aquarium’s total volume should be used for this. You should know the approximate amount of water that needs to be replaced based on whether it is a 3-liter or 4-liter. One third if this is the first choice, and one fourth if it is the second.

A hose should be used to remove the liquid. In this instance, you should either use filtered water or let the water settle before adding it to the aquarium.

This kind of procedure is required to lower the concentrations of nitrogenous materials, salts, phosphates, and regular organics. Moreover, cleaning in conjunction with water changes lowers the concentration of pharmaceuticals in the water.

What to do if the water in the aquarium turns green

Aquarium water that has turned green is a fairly common issue. This is usually the result of careless handling, but occasionally it may indicate the presence of bacteria in the water. Additionally, you can break the process down into three main stages to stop it:

1. Resettlement of underwater inhabitants.
2. Aquarium treatment.
3. Prevention of the problem.

It’s important to keep in mind that if you skip even one cleaning step, it will be very difficult to get the desired outcome, so you must complete every step.

Resettlement of underwater inhabitants

Prior to beginning the process of cleaning the brown or green plaque and protecting your little underwater ecosystem from pollution, you should triple the relocation of all the inhabitants to a different tank. Here’s how to accomplish it:

• Transfer all the fish to another aquarium, where all the conditions for life will also be met.
• Next, you can remove all the plants and place them in a prepared solution consisting of water and methylene blue.
• Thoroughly wash all the soil, but it is better to carefully examine its condition and if it is no longer suitable, you should replace the soil with a new one.
• After the entire aquarium has become transparent again, you can return all the inhabitants to their native aquarium, but first you should wait a day.

Tank treatment

We have already talked about a number of methods for clearing the tank of plaque earlier. However, the following is how to clean the tank using green water:

• Drain the water from the aquarium.
• Clean all the decorative elements in the aquarium, using brushes with a brush attachment and sponges for this.
• The container itself should be cleaned with a scraper.

Lifesaver! Aside from regular fish, you can also introduce creatures like snails, catfish, or even pecilias, which are excellent at controlling the growth of algae that cause the water to turn green.

The following actions should be taken in order to manually clean the aquarium:

• Adjust the lighting power.
• Make sure that the water is at the optimal temperature.
• Eventually, give up dry food and switch to natural frozen food.

It wouldn’t be unnecessary to purchase extra equipment in addition to the previously mentioned crucial points. The topic of discussion is a water sterilizer. It will support keeping the aquarium’s water level at the necessary level in the future.

Use specific tablets or liquids for chemical cleaning of the tank. They prevent bacteria from proliferating. Certain substances ought to be a part of the composition.

Activated carbon can also be used in place of such compositions. You must powder a few tablets and then pour the mixture into the filter in order to accomplish this.

Preventive actions

Preventive measures should, of course, be implemented without fail in order to either completely eliminate the possibility of such an issue in the future or to minimize its likelihood. The following actions will assist in resolving this issue:

• Place the aquarium so that the sun"s rays do not fall at all.
• When you place the soil on the bottom of the aquarium, do it at a slight angle towards yourself.
• Even the backlight power matters. It will be optimal to set 0.5 W per liter.
• Do not forget to simply turn off the lighting from time to time so as not to provoke the growth of algae.
• Use a special lid for the aquarium to keep dust and insects out.
• Periodically check that everything works.
• On a regular basis, you should clean the decorative parts and change the water.

These suggestions do not grant you permission to stop changing the water, but they do allow you to lessen the amount of greenness in the water by effectively delaying the growth of bacteria inside the tank.

Method	Description
Mechanical	Use an algae scraper or brush to manually remove the green plaque from the aquarium walls. Regularly clean the glass and decor to prevent build-up.
Biological	Introduce algae-eating fish or snails that naturally consume the green plaque. Maintain a balance in water quality by adjusting lighting and nutrient levels to inhibit algae growth.

Green plaque can be avoided in a home aquarium by using a combination of easy mechanical techniques and organic biological solutions. Algae buildup can be avoided by routinely cleaning the tank and using the right tools to scrub the decorations and glass. Keeping up a routine is crucial to maintaining a clean and healthy aquarium environment.

Biological techniques, such as introducing fish or snails that consume algae, can naturally reduce green plaque in addition to mechanical cleaning. Controlling the amount of light exposure and the amount of nutrients in the water are also essential for preventing the growth of algae.

You can have a clear, healthy aquarium by combining mechanical and biological methods. Green plaque can be prevented from building up on the tank’s walls with regular maintenance, letting you enjoy the beauty of your aquatic setting.
