Cleaning Supplies Needed
If you’re looking to clean an old or used fish tank, here’s a list of supplies that you’ll need to start the cleaning process.
Soap/Detergent
Scrubbing the tank with soap or detergent is an effective way to deep clean your fish tank. When cleaning a second-hand or old aquarium, it’s important to use a mild soap that won’t damage the tank and any decorations inside. You’ll also want to choose a detergent free from bleach or other harsh chemicals.
Sponge/Cloth
Using a soft sponge or cloth is essential for providing a thorough clean without scratching surfaces. It is used for physically removing debris, controlling algae, avoiding glass scratches, absorbing excess water, reaching tight spots.
Bucket/Bowl
Gathering a bucket or bowl for your cleaning supplies is essential for getting the job done quickly and efficiently. Use a clean, large enough bucket that can handle hot water or even boiling water if needed. Fill it with warm tap water and add a mild detergent and/or vinegar solution, then soak all removable parts of the tank (filter, pump, decorations) in this solution.
Make sure to rinse thoroughly with fresh water to remove any trace of soap from the parts before reassembling them back into the aquarium. If using a bowl instead of a bucket, fill it with warm tap water mixed with detergent and/or vinegar solution – just enough to submerge all items you wish to clean.
Soak each item in this mixture for at least 10 minutes before rinsing off thoroughly with fresh water. This will help disinfect old equipment without damaging any delicate surfaces or materials.
Gloves/Mask
Wearing gloves and a mask while cleaning an old aquarium is important for personal protection. Gloves help prevent direct contact with potentially harmful substances, such as algae, chemicals, or bacteria that may be present in the water or on surfaces. A mask can help filter out fine particles or aerosols that may be released during cleaning, reducing the risk of inhaling any irritants or pathogens. By wearing gloves and a mask, you can ensure a safer and more hygienic cleaning experience.
Scrubber/Brush
Using a scrubber or brush while cleaning an old aquarium is beneficial for effectively removing stubborn algae or debris from various surfaces. A scrubber or brush with soft bristles can be used to gently scrub the glass, decorations, or hard-to-reach areas, helping to dislodge and remove buildup. It allows for more thorough cleaning and helps maintain the overall cleanliness and appearance of the aquarium. However, it’s important to choose a scrubber or brush specifically designed for aquarium use to prevent any potential damage to the glass or delicate surfaces.
Vinegar and Salt
Using vinegar and salt is a great way to quickly and effectively remove algae build-up from your aquarium walls. Vinegar and salt can be used as a natural cleaning solution for an old aquarium. Vinegar, particularly white vinegar, is known for its cleaning properties and can help dissolve mineral deposits and remove stubborn stains. Salt acts as an abrasive agent, aiding in scrubbing away algae or grime.
To use vinegar and salt, you can create a mixture by combining equal parts vinegar and warm water in a spray bottle or bucket. Add a small amount of salt to the mixture and stir until dissolved. Then, spray or apply the solution to the surfaces of the aquarium and let it sit for a few minutes to loosen the dirt or algae. Use a sponge or brush to scrub the surfaces gently. Rinse thoroughly with clean water afterward to remove any residue.
It’s important to note that vinegar and salt should be used with caution and sparingly in an aquarium. After cleaning, make sure to rinse the tank thoroughly to remove any residual vinegar or salt solution, as these substances can be harmful to the aquatic life if left in the water.
Pro Tip: When using vinegar and salt for cleaning an aquarium, it’s crucial to avoid using excessive amounts. Overuse of vinegar or salt can disrupt the delicate balance of your aquarium’s water chemistry. Always rinse the tank thoroughly after cleaning to remove any residual solution and monitor the water parameters to ensure a safe and healthy environment for your fish.
Step-by-Step Process To Clean an Old Fish Tank
Cleaning an old or used fish tank can be a daunting task, but with the mentioned supplies and a step-by-step process, you’ll have your aquarium looking like new in no time.
Follow this step-by-step guide and your fish will soon be ready for their new home!
Step 1: Drain Water
Start by draining the water out of your aquarium – it’s easier than you may think, and it can be done quickly!
To begin, get a bucket that’s large enough to hold all of the water from the tank.
Next, use a siphon to remove as much water as possible from the tank. Be sure to move any decorations or substrate away from the siphon so they don’t get sucked up into it.
Then, fill up your bucket with water until it reaches capacity.
Now that you’ve drained all of the existing water, let’s move on to removing decorations for a thorough cleaning.
Step 2: Remove Decorations
Gently remove any decorations from the aquarium for a deep clean. When cleaning an old or used fish tank, it’s important to take out all of the decorations and substrate before beginning the cleaning process.
To do this, wear the gloves and use your hands or net to carefully remove:
- Aquarium gravel
- Substrate materials like crushed coral, aragonite, etc.
- Filter media like sponges and activated carbon
- Decorations such as rocks, plants, driftwood, and any other accessories that may have been added over time.
Take care to avoid scraping or scratching the glass panes as you move these items around in the tank. Be sure to check for any debris that may be hidden in crevices of larger decorations too!
Once everything is removed from the tank, you’re ready to move onto rinsing and drying – which will help restore clarity and prepare your aquarium for its new inhabitants.
Step 3: Rinse and Dry the Tank
Now that you’ve removed all the decorations, it’s time to rinse and dry the tank. Start by filling the tank with clean water until it’s around two-thirds full.
Next, use a cloth or sponge to wipe down the inside walls of the tank. Make sure you also run water over any acrylic surfaces on the outside of the tank to help them remain clear and free from dirt.
Once done, empty out the water from your tank and use another clean cloth to dry off both inside and outside surfaces before refilling your aquarium with fresh, clean water. This will give your fish a safe environment in which they can thrive!
Step 4: Clean Filter
Once you’ve finished rinsing and drying the tank, it’s time to clean the filter. An old or used fish tank filter may contain traces of old food, dirt, debris, and other contaminants that can be unhealthy for your fish if not removed properly.
To clean a filter, start by unplugging any power source connected to the filter. Then, remove the parts of the filter from the tank and rinse them in lukewarm water. If necessary, use an aquarium cleaning brush or pad to scrub off any stubborn dirt particles.
After cleaning each part of the filter according to its instructions, reassemble it back into its original form and plug it back in.
When learning how to clean an old aquarium or second-hand fish tank, make sure you don’t miss out on this essential step as a dirty filter can cause problems with your water quality.
Step 5: Cleaning the Tank Interior
Cleaning the interior of an old or used fish tank is a necessary part of aquarium maintenance. Start by scrubbing the sides with an algae pad, making sure to get into all of the nooks and crannies.
Next, use a gravel vacuum to clean the bottom of debris and waste that has collected over time.
With a little elbow grease and attention to detail, you’ll have your fish tank looking as good as new in no time!
Scrubbing the Sides
Scrubbing the sides of an old or used fish tank is essential to ensure it’s properly cleaned – a little elbow grease never hurt anyone! To get the job done, use:

- Hot water and detergent to remove dirt and grime.
- A soft cloth for finishing touches.
Cleaning the bottom is next – let’s get started!
Cleaning the Bottom
Now that you’ve scrubbed the sides, it’s time to tackle the bottom of your aquarium – don’t forget to give it a good clean!
Start by removing the substrate, such as gravel or sand. To do this, use a siphon to suction out old water and any debris.
After all of the substrate has been removed, rinse out the tank bottom with warm water and mild detergent. Use a soft cloth or sponge for extra cleaning power if needed.
Allow it to air dry before replacing substrate for best results.
Once you’ve cleaned out the bottom of your tank, you’re ready to move on to replacing the substrate and bringing back life into your old aquarium!
Step 6: Replace Substrate
Replacing the substrate is an easy way to give your tank a fresh start. If you’re looking for the best way to clean an old fish tank, removing and replacing the substrate is one of the most effective methods.
To begin, use a net or vacuum to remove any residue or debris that may have built up in the bottom of your dirty fish tank. Once all of this material has been removed, it’s time to replace the substrate with a new layer.
Pour a few inches into the bottom and spread it around evenly before adding more until it reaches your desired depth. This will help make sure that no areas are left uncovered as part of your deep cleaning efforts for how to clean an old fish tank.
Replacing the substrate can be a great way to get rid of any unpleasant odors and give your aquarium a fresh appearance – perfect for starting anew!
Step 7: Disinfect Tank
To ensure a safe, healthy environment for your aquatic friends, disinfecting the tank is an important step in the cleaning process. To properly disinfect your empty fish tank or old saltwater tank, you need to use a mild bleach solution and rinse it off thoroughly.
Mix a solution of one part bleach to 10 parts water and scrub down the interior surfaces of the new tank with it. Be sure not to leave any residual bleach behind!
For live plants, you can simply rinse them with water and add them back into the aquarium.
Finally, rinse all decorations and other items that will be added back in with fresh water before placing them inside.
Step 8: Wash Decorations and Plants and Add Them Back
After rinsing off any lingering bleach, you can put the decorations and plants back in your aquarium for a colorful display. It is imporant to learn how to clean fish tank decorations for an algae free aquarium.
First, inspect the tank to check for any residual chemical residue from cleaning supplies.
Next, rinse out all ornaments with warm water before adding them back into the tank.
When adding new items, make sure they’re safe for aquatic life and don’t contain any toxins that could harm your fish. If you’re unsure, it’s best not to risk it and choose another option instead.
Also, ensure that the items are suitable for your fish’s environment and won’t cause stress or overcrowding if added in.
Once you’ve made sure everything is safe, carefully place the decorations and plants back into the tank where they will look their best.
Step 9: Refill Tank
Now that your decorations and plants are clean, it’s time to refill the tank. Begin by positioning the tank so it is level and won’t wobble. Fill the tank up with water until it reaches the desired level, usually about two inches below the top rim of the tank. Make sure you’re using purified or tap water that’s been treated with a dechlorinator, as chlorine can be deadly for fish. Now add any accessories such as a filter or heater if you have them, and then attach all air hoses and/or power cords that connect these items to the outside of the aquarium. With everything in place, plug in all cords and turn on any pumps or filters associated with your setup.nnAfter allowing time for everything to settle in, you can now move on to reintroducing fish into their new home!
Step 10: Reintroduce Fish
With your pristine aquatic paradise ready and waiting, it’s time to bring in the stars of the show – your fish! Start by acclimating them to the new water.
To do this, float the sealed bag containing their previous water in the tank for at least 15 minutes. This allows them to adjust gradually to any changes in temperature or chemistry.
When you’re ready, open up the bag and slowly pour out some of their old water while adding a cup or two of fresh tank water every few minutes. After about 20 minutes, they should be ready for release into their new home.
Pro Tip: When reintroducing fish into a newly cleaned tank, it’s important to monitor the water parameters closely. Perform regular water tests to ensure the ammonia, nitrite, and nitrate levels are within acceptable ranges. Additionally, consider adding a beneficial bacteria supplement to help establish a healthy biological filter and promote a stable aquarium environment for your fish.
Additional Tips (Advanced Things To Consider)
Apart from the above mentioned steps, there are some additional things that you may want to consider while setting up an old fish tank. Here are some of those advanced things that you should consider.
Check for Leaks in the Used Fish Tank
Examine the used fish tank and make sure it doesn’t have any leaks. Fill the tank with water to check for visible leaks, then use a flashlight and inspect around the seams, edges, and corners of the tank.
