It’s also important to have a plan before cleaning the fish tank, so you can be prepared and not miss anything that needs cleaning.

How you should Clean out your Aquarium

Clean your aquarium in the following order:

  1. Take care of the Cleaning
  2. Turn Off Your Filter and Unplug Your Heater
  3. Cleaning Decorations and Rocks
  4. Scrubbing the Inside Glass
  5. Clean Aquarium Gravel using a Siphon
  6. Clean the Tank Filter
  7. Fill the tank with fresh water
  8. Outside Glass and Equipment
  9. Monitor the Tank

1. Take care of the Cleaning

Put on a large T-shirt and organize all your materials in a convenient location. Next, thoroughly clean your hands and lower arms. This process, known as “scrubbing in” among doctors, helps prevent the introduction of harmful substances into your aquarium water. Remember to completely remove any soap residue.

2. Turn Off your Filter and Unplug Your Heater

It is recommended to turn off your aquarium filter while cleaning as debris can easily be removed from the bottom of the tank rather than getting sucked into the filter.

Additionally, when performing water changes or cleaning the heater, it is important to unplug the heater to avoid burning out the machine. This is because exposing the heater to air while it is still hot can cause damage. Allow the heater to cool before continuing with the cleaning process.

3. Cleaning Decorations and Rocks

After ensuring that the aquarium glass is spotless, remove any rocks, artificial plants, and decorations with a significant amount of algae growth. It is difficult to remove residue with soap or detergents completely, and even the slightest amount can cause harm to the fish. You can remove algae and dirt from rocks and plants by using an algae scraper and warm water.

If your cleaning issue is particularly stubborn, you can soak the items in a 10% bleach solution for 15 minutes. Rinse thoroughly with running water and allow to air dry to eliminate residual bleach. Wait until the aquarium is free of chlorine odor before placing back. Alternatively, you can rinse them in water that has been treated with a de-chlorinator such as sodium thiosulfate to remove any chlorine.

A 5 percent bleach solution can be used to remove algae from live plants. However, it is important to note that stem plants are not suitable for bleaching. The process involves soaking the plants for a duration of 2-3 minutes before rinsing them thoroughly. When cleaning the tank, it is recommended to remove all rocks, decorations, and plants to prevent debris from settling on them while vacuuming the gravel.

Additionally, it is important to use a new bucket specifically designated for aquarium use to avoid introducing any unwanted chemicals from soap or detergent.

4. Cleaning the Inside Glass

Cleaning the inside walls of your tank is another crucial step in maintaining a healthy aquarium. As time goes by, algae and other debris can accumulate on the walls, which can affect the overall appearance and water quality of your tank.

To clean the walls, use a scraper or a sponge specifically designed for aquariums. Gently scrub the walls, being careful not to damage the decorations or plants in the tank. You can also use a solution of water and vinegar to remove stubborn algae buildup.

It’s important to note that while cleaning the walls, you should also pay attention to the corners and edges of the tank, as these areas tend to accumulate more debris.

Once finished, rinse the scraper or sponge thoroughly before using it again to avoid introducing any harmful chemicals into your tank. Additionally, make sure to rinse the walls of the tank with clean water to remove any remaining cleaning solution.

5. Clean Aquarium Gravel using a Siphon

Cleaning the gravel, and the small rocks that sit at the bottom of your tank is an important step in maintaining a healthy aquarium. As tanks age, they tend to accumulate detritus, or the decomposed remnants of leftover food, fish waste, and decaying particulate matter. This detritus can settle between the small rocks and build up, causing health issues for your fish.

To effectively clean the gravel, a gravel vacuum is a must-have tool. This device, consisting of a plastic siphon attached to a length of tubing, removes large amounts of dirty aquarium dust. To use it, simply submerge the siphon in the water to create a suction that pulls water from the tank through the tube into a bucket. The amount of vacuuming required will depend on the level of dirtiness in your tank. When the water pulled through the siphon is no longer cloudy and gray/brown, your gravel is clean.

Once finished, don’t discard the water in the bucket just yet as it will be used in the next step.

6. Clean the Tank Filter

Cleaning the tank filter is an important step in maintaining a healthy aquarium. The filter is responsible for removing debris, waste, and toxins from the water, so keeping it in good working condition is essential.

To clean the filter, first, turn off the power to the filter and remove it from the tank. Then, disassemble the filter according to the manufacturer’s instructions. This will typically involve removing the filter media, such as activated carbon or ceramic noodles, and cleaning or replacing them as needed.

Next, use a brush or a sponge to clean the filter housing, paying close attention to the impeller and other moving parts. Make sure to remove any debris or buildup that may be present. You can also use a solution of water and vinegar to remove stubborn grime.

Once finished, reassemble the filter and place it back in the tank. Turn the power back on and check for any leaks or other issues.

It’s essential to clean the tank filter regularly, as a dirty filter can lead to poor water quality and can also be harmful to your fish and other aquatic inhabitants. Cleaning the filter every two to four weeks is usually sufficient, but it’s essential to monitor the water quality and adjust the cleaning schedule as needed.

7. Fill the Tank with Fresh Water

It is crucial to ensure that the new water added to the tank after siphoning out the dirty water is properly prepared. This includes making sure the temperature is similar to the existing water and treating the water with a conditioner to remove any harmful chlorine and chloramines present in tap water. To do this, fill a bucket with tap water and use a thermometer to adjust the temperature as necessary.

Follow the instructions on the water conditioner and add the appropriate amount for the number of gallons being introduced to the tank. Slowly pour the treated water into the tank, taking care not to shock the fish. Once all the water has been replaced, the heater and filter can be turned back on.

8. Outside Glass and Equipment

After completing the cleaning of the interior of the aquarium, it is important to also clean the exterior glass, as well as the hood, light, and tank top. It is crucial to avoid using regular glass cleaners as they contain ammonia which can harm the fish. Additionally, using standard lime cleaners is even more toxic.

how to clean your fish tank

Using either vinegar or a cleaner specifically labeled as safe for aquariums is recommended and thoroughly rinse the surfaces with a clean, damp cloth.

9. Monitor the Tank

Monitor the tank for a few minutes to make sure everything is working properly and the fish are not stressed.

By following these steps regularly, you can ensure that your aquarium is clean and safe for your fish to thrive in. Remember to always test the water quality before cleaning and to use appropriate tools and techniques for cleaning different parts of the tank.

Here are Some Tips to Keep an eye out for

Several factors affect how often you should clean out your fish tank, including its size, the types and the number of fish, and its filtration system. A daily cleaning routine is not necessary unless you notice any unusual behavior from your fish, such as gasping for air or lethargy. In such cases, a partial water change is recommended.

  • For average-sized or large fish tanks, it is beneficial to perform weekly partial water changes to maintain the cleanliness of the tank and the health of the fish.
  • Furthermore, monitoring the pH, nitrate, and ammonia levels in the tank can help identify potential problems and maintain consistency.
  • Watch your fish’s behavior and the appearance of the water as a general rule.
  • If the fish appear distressed or the water is cloudy, it may be necessary to perform a partial water change.
  • Keep in mind that the well-being of your fish is in your hands, so take the time to observe them and understand their routine.
  • Keep track of water evaporation in the tank and examine all equipment twice a year to ensure proper operation.
