how to clean a fish tank

Many times it falls into the consideration that the world of fish needs much less care than that of any other animal, and this is great confusion. There are many cares for the pet to have the best possible well-being, among them is its lighting, cleaning of the aquarium or the routine of changing the water. This time we are going to focus on the latter since cleaning is a fundamental part of the fish health i.e. how to clean a fish tank.

Many people consider that by having a filter in the fish tank they no longer have to continually change the water of their pet, and this is another big mistake since the filter is helping to preserve the cleanliness of the water in the aquarium, but it does not clean it completely.

So it is recommended that the aquarium water be changed once or twice a week. Given this, there will be many people who wonder how to do it since this action requires certain care and delicacy, especially with the fish that you will have to remove from their usual environment.

The filter of an aquarium does not help to clean completely. For all this, and based on the advice we are going to give you below, the changing of fish water will become a few simple steps in which you will ensure the well-being of your animals at all times. You might consider it as the natural way to clean a freshwater fish tank.

Find a surface to house the fish

The first step you will have to do is find a place similar to the aquarium where you will house the fish while you are changing the water. When you have chosen a container, you will have to make sure that it does not have soap residues, as this can be harmful to animals.

This will have to be done the night before so that the water on the surface where you will later place your pets settles and has a temperature similar to that of the fish tank and that the chlorine levels drop. It is advisable not to project sunlight or other artificial light directly onto the tank as this can cause the temperature to vary .

The first thing you should do is move the fish around If you do not have time to do all these things and want to change the water in a hurry, you can also use a dechlorinator , with which you can obtain the same result and in a much faster way.

Move the fish

Once you have verified that the water in the new container is at the same temperature as that of the fish tank and we have removed the chlorine, we can proceed to transfer the fish.

This should also be done with special care so that the pet suffers as little as possible. What some people do is catch the fish with a fishing net and place the new container near the fish tank so that the time the animals are out of the water is as short as possible and they do not suffer. 

Another more advisable alternative and with which there will be no risk of the pets suffering is inserting a small round object inside the aquariumthat does not contain soap residues.

Once it is submerged in the water, you will have to wait for the fish to enter its interior and when this has been achieved you will only have to remove it from the fish tank.

Changing the dirty water from fish tank

When we have evacuated the fish, it will be the turn to change the water in the tank. To do this, and be careful not to throw the objects that are inside such as plants or rocks for the fish to play, you must remove the dirty water.

Once this is done, the best thing to do so that all its contents are clean is to remove the objects that were inside, place them in another container and wash them with hot water and salt.

You should also clean the decorative objects that are inside the fish tank

Clean fish tank objects

When this has been achieved, all the objects that were in the tank that have also been cleaned will be reintroduced and the aquarium will be filled with water.

In the latter case, the same steps that have been carried out previously will have to be followed to prepare the container in which the fish were to be found during the aquarium cleaning.

So you will have to clean the water and make sure that it does not have chlorine and is at the same temperature as the other container where the animals are.

Transfer the fish to the clean water

And in the same way that the animals have previously been moved from one place to another, this time it will be carried out to the aquarium after having changed the water and having it ready again for their enjoyment and health .

If this is the first time that you are going to change the water in the aquarium, it is recommended that you be accompanied by another person to help you carry out all these steps in the most appropriate way and with the greatest care.

It would also be good if one person is in charge of changing the water, another is watching the fish at all times. Since these in many occasions can jump, reason why it would be necessary to put a lid on top of the container so that they do not leave it.

How often to clean a fish tank

The frequency of changing water should be part of proper aquarium maintenance. Still, the frequency may vary slightly depending on the aquarium volume and the quantity of fish. Smaller and more stocked tanks require water to be changed more often than larger aquarium tanks.

It would quite better rule is to change 10% to 15% of your water every week. If the tank is large, increase it by up to 20% weekly. A small aquarium can take 2 to 4 weeks, but this should be the maximum time for the water to change.

Final thoughts

Partial water changes are the main aspect to keep your fish happy and healthy. This will not remove or damage the bacterial colonies that are essential for your aquarium.
