Fish tanks are able to create a unique atmosphere in any room, no matter if it comes to your home, office, another public building, a hotel or a high-class restaurant. However, the impression created by it will not be the same if the tank is dirty and poorly maintained, and filled with muddy water and greenish mossy walls. All of this affects not only the appearance of the fish tank; it also affects the inhabitants of the tanks’s polluted environment, because fish that live in the dirty water, usually languish, lose their beauty and die due to putrefactive processes and lack of oxygen.

Food remnants, fish waste and rotting plants are considered to be the most common tank pollutants. They are all gathered on the bottom of the tank and form a thick layer of slime, which results in getting the water dirty, no matter if this is visible to us, or it is not. That is the reason why your tank at home or in the office needs regular cleaning and maintenance, which basically means mud and slime elimination, fresh water pouring, dechlorination and treatment with some special detergents. Remember that regular fish tank cleaning will save you a lot of other long-term troubles.


What tools do you need in order to clean your fish tank?


You have all probably wondered how you are supposed to clean a dirty tank properly. Do you have to empty it, wash everything and fill it once again with some fresh water or just clean it without ruining it completely?


The answer is that by emptying your tank, you will kill all the colonies of useful bacteria that are reliable for processing the waste products in your tank. That is the reason why you don’t have to ruin it completely, unless of course, it is in an extremely poor condition.


Here are the tools that you will need in order to keep your fish tank at home or in your office clean and well-maintained:


  • scraper;
  • bleach or other special detergent;
  • siphon;
  • bucket;
  • glass cleaner;
  • filter brush;
  • old towels;
  • paper napkins


And here is the proper order of cleaning procedures that you need to perform in order to keep the fish tank clean and safe for your fish:


1. Clean the glass of the tank from the inside.


2. Cleaning all decorations, artificial and real plants.


3. Siphoning the ground of the tank.


4. Cleaning the glass surfaces from the outside


5. Washing the tank’s filters and replacing them if necessary.




Scrapers are used for cleaning the walls of the tank from moss and slime. Start with cleaning the glass from the inside. There is a great variety of scrapers in the specialized stores you can choose from, but basically, any scraper will be appropriate. If there are any stubborn spots and particularly dirty areas, you can choose a razor blade scraper, but you should be careful not to damage the glass surface.


Bleach and special detergents


Once you have cleaned the glass surface of the tank from the inside, remove all decorations and artificial plants that are dirty and wash them. Do not use any soap, because it is quite difficult to remove, and it is usually toxic to your fish. Use a rough sponge, and if there are some particularly stubborn dirty stains, use a 10-percent bleach solution. Be careful not to use too much, because bleach can also be poisonous to your fish.




Clean the ground of your fish tank by using a siphon. There are different types of siphons which you can choose from. Most of them are equipped with a tap that is used to adjust the suction. Remember to be careful when working through the entire surface of the ground in order to suck all the dirt.


Glass cleaning products


After you have cleaned your fish tank from the inside, make sure you also clean the glass from the outside, too. Be very careful with the use of any chemicals or glass detergents, because most of them contain ammonia, which is highly toxic to fish. Use detergents that contain vinegar or products that are especially made for cleaning tanks.


Regular maintenance


Once you have thoroughly cleaned your fish tank at home or in the office, do not forget to keep it that way. Clean the glass from the outside every week and clean the tank’s ground regularly.
