Maintaining the health of your fish and plants in an aquarium requires regular water changes. Maintaining a balanced environment for your aquatic life is made easier when you understand the process, whether you’re doing a full or partial water change.
To keep your fish in a healthy and safe environment, partial water changes are an easy chore that can be performed on a regular basis to get rid of waste and toxins. On the other hand, in some situations a full water change may be required; however, extra caution is needed to prevent shocking your fish.
Understanding when and how to do these water changes can significantly improve the health of your aquarium. You can maintain a healthy aquatic environment and happy fish with the appropriate strategy.
Type of Water Change | Steps |
Complete Water Change | 1. Move fish to a temporary tank. 2. Empty the aquarium completely. 3. Clean the tank and decorations. 4. Refill with treated water. 5. Allow water to reach the right temperature. 6. Return fish to the tank. |
Partial Water Change | 1. Turn off equipment. 2. Remove 20-30% of the water. 3. Vacuum the gravel to remove debris. 4. Refill with treated water. 5. Turn equipment back on. |

Why do you need a change?
Learn about all the procedures that take place in aquariums before determining when the water needs to be changed.
- Over time, aquarium water gradually becomes polluted. Dead plants, food remains and other waste products of fish accumulate.
- The level of nitrates in the water increases against the background of the process of decay of waste products. Nitrates are considered very harmful for aquarium inhabitants.
- Number nitrites in water gradually increases and plants can no longer cope with them.
- Some aquarium fish can live in water poisoned with nitrates, but this has a strong impact on their health – the immune system weakens.
- Nitrogen compounds in water also have a negative impact on aquarium vegetation, which creates optimal conditions for the development of bacteria and fungi.
- Now the likelihood of developing an invasive, fungal or bacterial epidemic increases significantly. And fish whose immunity is weakened due to the presence of poison in the water will no longer be able to survive this outbreak.
Kindly take note! The only way to lower the nitrate content of an aquarium is to replace some of the water. This issue cannot be resolved by using either special preparations or contemporary filters.
Replacing aquarium water can also be done to bring the pH level back to normal. Acids are progressively produced in all kinds of aquariums, and they are broken down by the mineral elements in the water. Consequently, minerals bring the aquarium’s alkalinity level back to normal. However, the water’s mineral content will decrease over time if you don’t regularly change it, making it insufficient to break down acids.
The water’s gradual increase in acidity will be detrimental to the health of the aquarium’s occupants. All of the fish will perish if the acidity level reaches a certain point. Regular water changes are the only way to ensure that the aquarium’s inhabitants don’t suffer a terrible end.
How often to do this
In order to ascertain how often the aquarium needs to be replaced, you must first ascertain its age. Three categories apply to them: new, young, and mature aquariums. Let’s examine each group in isolation.
New aquarium
New tanks are those that have been filled in less than eight weeks. In these situations, changing the water is not necessary too frequently because the aquarium’s ecosystem is still quite fragile and hasn’t had time to settle. As a result, replacement should only be considered after three to four months. It is best to decline changing the water altogether at the beginning if the fish in the aquarium are comfortable and feel fine, the water is clear, and there isn’t any bad odor.
Young aquarium
If an aquarium was launched less than six months ago, it is deemed young. Now that the ecosystem is stabilized, you can begin replacing the water. Experts advise periodically draining and replacing 10% to 15% of the aquarium’s water. Don’t empty the aquarium of more than 25% of its water to prevent upsetting the natural equilibrium. If not, an infection might develop.
Mature aquarium
If the fish have been in the aquarium for longer than six months, then the aquarium is deemed mature. The frequency of water changes in the aquarium can vary depending on the inhabitants. For instance, it is advised to empty 25% of the water from round or rectangular tanks once a week and replace it with fresh water. However, you need to change the water in the aquarium less frequently the larger it is.
Performing routine water changes is essential to keeping the environment in an aquarium healthy. You can maintain the health and growth of your fish and plants by knowing when and how to do partial and complete water changes.
In order to maintain stable water conditions without upsetting the aquarium’s equilibrium, partial water changes assist in the removal of waste and toxins. On the other hand, in certain circumstances, like a major contamination or a serious problem with the quality of the water, complete water changes are required.
To prevent stressing your fish, remember to adjust the new water’s parameters and temperature to the ones already present in your aquarium. Your aquarium can remain a stunning and lively habitat for your aquatic creatures as long as it is properly maintained.
To keep fish and plants in an aquarium in a healthy environment, the water must be changed frequently. It’s crucial to follow the correct procedures when performing a full or partial water change to prevent stressing out your aquatic animals. While complete changes might be required in some circumstances but should be done carefully, partial changes help remove toxins and keep the water clean without upsetting the tank’s balance. It is important to know when and how to make each kind of change so that your aquarium maintains a healthy, balanced ecosystem.
