Emptying a fish tank is a task that every aquarium owner will have to undertake at some point. Whether you are moving, cleaning the tank, or simply replacing the water, it is important to know the proper way to do it. If not done correctly, you can harm your fish or damage your tank.
The first step is to gather your supplies. You will need a clean bucket, a siphon, a gravel vacuum, and a water conditioner. If you are moving your fish, you will also need a new tank and some water from the old tank. Once you have your supplies, you can begin the process of emptying the tank. Start by siphoning the water out of the tank. Be sure to use a siphon that is large enough to remove the water quickly and efficiently. As you siphon the water, use a gravel vacuum to clean the gravel. This will help to remove any dirt or debris that has accumulated.
Once the tank is empty, you can remove the fish. If you are moving the fish to a new tank, be sure to use a net that is large enough to accommodate them. Do not put the fish directly into the new water. Instead, float the bag in the new water for about 30 minutes. This will give the fish time to adjust to the new temperature and pH level. After 30 minutes, you can release the fish into the new tank. Finally, add water conditioner to the new water. This will help to remove chlorine and chloramines from the water, which can be harmful to fish.
Draining the Water
1. Turn Off and Disconnect Equipment
Before you begin, turn off all electrical equipment in the tank, including filters, heaters, and lighting. Unplug these appliances to prevent any risk of electrical shock.
2. Remove Water Decorations and Accessories
Carefully remove any rocks, plants, decorations, or other accessories from the tank. Place these items in a separate container filled with tank water to keep them wet while you drain the main tank.
3. Use a Gravel Vacuum or Siphon to Remove Debris
To remove dirt, debris, and waste from the gravel substrate, you can use a gravel vacuum or a siphon.
Gravel Vacuum: This device is specifically designed to clean gravel. It sucks up the substrate surface and separates the waste from the gravel. Follow the manufacturer’s instructions to assemble and use the gravel vacuum.
Siphon: A siphon is a simple tube that creates suction when one end is placed in the tank and the other end is below the water level. To use a siphon, start the flow by sucking on the lower end until water begins flowing. Then, submerge the lower end in the gravel, and it will continue to draw water and debris from the tank.
| Gravel Vacuum | Siphon |
|---|---|
| Efficiently removes dirt and debris from gravel substrate | Requires manual suction to initiate flow |
| Easy to use and clean | Can be messy if not handled carefully |
Removing the Fish and Plants
1. Catching the Fish
Gently use a fishnet to scoop up the fish. Avoid chasing them, as this can cause stress. If necessary, use a small container to temporarily hold the fish while you prepare the new tank.
2. Removing the Plants
Carefully remove the plants from the tank. Use your hands or a pair of tweezers to gently grasp the base of the plant and pull it out. Avoid damaging the roots or leaves.
3. Transferring the Fish and Plants
Place the fish and plants in the new tank filled with clean, dechlorinated water. Ensure the water temperature and pH levels are similar to the original tank.
4. Replicating the Ecosystem
Recreating the fish tank’s ecosystem is crucial for the well-being of your aquatic inhabitants. Here’s a table summarizing the key elements to consider:
| Element | Importance |
|---|---|
| Water Parameters | Maintain proper pH, temperature, and water hardness to match the natural habitat of the fish and plants. |
| Filtration | Install a filtration system to remove waste, debris, and harmful chemicals from the water. |
| Lighting | Provide appropriate lighting to simulate the natural light cycle and support plant growth. |
| Substrate | Choose a substrate that mimics the natural environment of the fish and provides a suitable surface for plants and microorganisms. |
| Live Plants | Include live plants to provide oxygen, shelter, and natural food sources for the fish. |
| Microbial Ecosystem | Establish a balanced microbial ecosystem in the filter and substrate to break down waste and maintain water quality. |
Cleaning the Substrate
1. Remove Large Debris
Remove any large debris, such as toys, plants, or hiding places, from the substrate using a net.
2. Siphon the Water
Partially siphon the water out of the tank, leaving a few inches of water above the substrate. This will help loosen the dirt and debris.
3. Stir the Substrate
Use a gravel vacuum or a clean spoon to stir the substrate gently. This will release the dirt and debris that has settled deep into the substrate.
4. Vacuum the Substrate
Connect a gravel vacuum to a siphon hose and insert the nozzle into the substrate. Slowly run the vacuum over the entire bottom of the tank, removing the loosened dirt and debris.
5. Rinse the Substrate
To further clean the substrate, remove the gravel vacuum from the siphon hose and use a clean bucket of water to rinse the substrate. Slowly pour the water over the substrate, agitating it gently to remove any remaining debris.
| Type of Substrate | Recommended Cleaning Method |
|---|---|
| Gravel | Gravel vacuum |
| Sand | Aquarium siphon with a sand-cleaning attachment |
| Soil | Clean bucket of water to rinse and agitate |
Scrubbing the Walls

Replacing the Water
Depending on the size of your aquarium, this step may require a bit of muscle. For smaller tanks, you can simply pour the water out into a bucket or sink. For larger tanks, you can use a siphon to drain the water. A siphon is a simple device that uses gravity to create a vacuum that sucks the water out of the tank. To use a siphon, simply attach one end of the hose to the discharge end of the siphon and the other end to a bucket or sink. Then, start the siphon by creating a vacuum in the hose. You can do this by sucking on the hose or using a pump. Once the siphon is started, it will continue to drain the water until the tank is empty.
Once the tank is empty, you can wash it out with clean water to remove any remaining debris. You can also use this opportunity to clean the filter and other accessories in the tank.
Now that the tank is clean, you can start refilling it with fresh water. Be sure to use water that is the right temperature for your fish. You can check the temperature of the water with a thermometer.
Once the tank is full, you can add your fish back in. Be sure to acclimate the fish to the new water before adding them to the tank. To acclimate the fish, float the bag they are in in the tank for about 15 minutes. This will allow the fish to adjust to the temperature of the new water.
After 15 minutes, you can release the fish into the tank. Keep an eye on them for a few hours to make sure they are adjusting to the new water properly.
| Water Chemistry | Recommended Levels |
|---|---|
| pH | 6.5-7.5 |
| Ammonia | 0 ppm |
| Nitrite | 0 ppm |
| Nitrate | Less than 20 ppm |
Restarting the Equipment
Once the tank is empty, it’s time to clean and restart the equipment. This includes cleaning the filter, heater, and any other accessories. It’s also a good time to replace the filter media if it’s looking worn or dirty.
To clean the filter, follow the manufacturer’s instructions. Generally speaking, you’ll remove the filter media and rinse it in cold water until the water runs clear. If the filter media is particularly dirty, you can soak it in a dechlorinating solution for a few minutes before rinsing it.
To clean the heater, simply wipe it down with a damp cloth. Do not immerse the heater in water, as this can damage it.
To clean other accessories, such as plants or decorations, rinse them thoroughly in cold water and allow them to air dry.

Monitoring Water Parameters
Monitoring water parameters is crucial for maintaining a healthy aquatic environment for your fish. Regular testing will provide insights into the water quality and alert you to potential problems before they escalate into major issues.
pH
The pH value measures the acidity or alkalinity of the water. Different fish species have specific pH requirements, so it’s important to determine the optimal range for your tank inhabitants. Use a pH test kit to monitor pH levels and make necessary adjustments using pH buffers or aeration.
Ammonia
Ammonia is a toxic substance produced by fish waste, uneaten food, and decaying organic matter. High ammonia levels can cause stress, respiratory problems, and even death for your fish. Test ammonia levels regularly and promptly perform water changes if they exceed safe limits.
Nitrite
Nitrite is another toxic byproduct of the nitrogen cycle. While nitrite is less harmful than ammonia, elevated levels can also cause health issues for your fish. Monitor nitrite levels carefully and make water changes if necessary.
Nitrate
Nitrate is the final product of the nitrogen cycle and is less toxic than ammonia and nitrite. However, excessive nitrate levels can still contribute to algal blooms and affect fish growth. Regular water changes help maintain nitrate levels within acceptable ranges.
Temperature
Water temperature is critical for fish health. Different species have specific temperature ranges they can tolerate. Use a thermometer to monitor water temperature and adjust it accordingly using heaters or chillers as needed.
Dissolved Oxygen (DO)
DO refers to the amount of oxygen dissolved in the water. Low oxygen levels can lead to fish gasping for air at the surface or even death. Ensure adequate oxygen levels by using an air pump, water agitators, or oxygenating plants.
Chlorine and Chloramine
Chlorine and chloramine are disinfectants commonly used in tap water. While necessary for human consumption, these chemicals can be harmful to fish. Always dechlorinate tap water before adding it to your tank using water conditioners or activated carbon filters.
