The Right Way to Clean a Fish Tank
If you have a fish tank, then you know that regular cleaning is essential to keeping your fish healthy and your tank looking its best. But what is the best way to clean a fish tank?
Unplug Filter and Lights Before Cleaning
Always unplug filters, lights, and any external devices before cleaning. For sump systems, close valves to prevent overflow. This protects equipment and prevents accidents while you tidy your tank.
Why Algae Isn’t Necessarily Bad for Your Fish Tank
When you spot algae in your fish tank, your first instinct might be to scrub it away immediately. However, it’s important to understand that algae can actually be a positive indicator of your tank’s health. Here’s why:
Signs of a Balanced Ecosystem
Algae play a crucial role in maintaining a balanced ecosystem within your aquarium. They are natural and often signal that your tank is supporting life effectively. This green growth is a part of the natural cycle, contributing to the tank’s environment by converting waste into oxygen and providing a food source for certain fish and invertebrates.
Minimal Impact on Fish
While algae might be unsightly, they generally don’t harm your fish. In fact, fish can swim comfortably even with additional algae. Unless your tank looks like a thick green soup or your fish are visibly struggling to move, there’s no need for drastic measures. Algae are a natural element that many aquarium residents are accustomed to.
You Can’t—and Don’t Need to—Eliminate Every Bit
It’s easy to become frustrated when algae keep returning no matter how much you clean. Good news: you’re not supposed to get rid of every last bit! Algae bother people far more than they bother the fish. Trying to win the battle against every molecule of algae is a losing game—and an unnecessary one. Unless your tank is so overrun that it’s difficult to see your fish or for them to swim, what you’re seeing is a normal part of a healthy tank.
Reducing Stress for Tank Owners
Attempting to eliminate every bit of algae can be an endless and stressful task. In reality, most hobbyists accept a certain amount of algae as part of regular tank maintenance. It only becomes problematic when it grows uncontrollably, which can typically be managed through balanced feeding, appropriate lighting, and regular cleaning.
How to Maintain a Healthy Balance
- Control Lighting: Too much light can lead to excessive algae growth. Ensure your tank receives an appropriate amount of light each day.
- Monitor Nutrients: Overfeeding can increase nutrient levels, promoting algae proliferation. Keep feeding times and quantities in check.
- Regular Cleaning: Routine maintenance without over-sanitizing ensures both fish and algae are kept in proper balance.
In summary, not all algae is bad. When present in moderation, it indicates a thriving fish tank ecosystem. Understanding how to manage and tolerate it can help maintain a stress-free and healthy aquarium for both you and your fish.
Here is a step-by-step guide to cleaning your fish tank the right way:
1. Empty the tank: Remove all of the water from the tank using a siphon or bucket. Be sure to remove all decorations, gravel, and anything else that could be disturbed during the cleaning process.
2. Clean the tank: Use a mild soap and warm water to clean the inside of the tank. Be sure to rinse everything thoroughly before moving on to the next step.
3. Clean the decorations: Soak all of the decor in a mixture of warm water and vinegar. This will help to remove any built-up algae or other debris. Rinse everything off before putting it back in the clean fish tank.
To tackle stubborn algae, take the décor to the sink and scrub it with a designated toothbrush. For particularly tough spots, you can let the pieces soak in hot—not boiling—water for a few minutes to loosen the grime.
Remember, do NOT use any detergent, as it can be harmful to your fish. Always ensure that all items are thoroughly rinsed to remove any vinegar residues or loosened debris before returning them to the tank.

4. Add fresh water: Fill the fish tank with fresh, clean water. You may want to use a water conditioner to make sure that the new water is safe for your fish.
Before starting, test your tap water for pH and KH levels. This ensures the water is suitable for your fish’s needs. If necessary, adjust by adding buffers or consider an alternative water source.
Not all tap water is created equal—some may lack essential minerals or the right buffers, while bottled water can be missing key elements your fish require. Testing beforehand takes out the guesswork and helps you avoid surprises.
Tip: If you’ve never checked your tap water before, now’s a great time. Test kits are inexpensive and widely available at pet stores.
Temperature is crucial—ensure the new water matches the tank’s current temperature. An infrared thermometer can quickly compare temperatures without cross-contamination. You might already have one in your kitchen or grilling kit.
When treating the water, add a dechlorinator that addresses both chlorine and chloramine. Carefully read product labels to confirm this. For large tanks, consider dividing the total dechlorinator dose into smaller portions. Add the first dose before adding water, and the rest in increments as you fill the tank. This step ensures your fish are not exposed to harmful chemicals during the refill process.
5. Put everything back: Add gravel, plants, and other decorations back into the fish tank. Slowly add your fish back into the tank, being careful not to overcrowd them.
When pouring the treated water back into the tank, make sure to do so slowly to prevent creating a strong current that could stress or harm your fish. Consider using a smaller vessel to transfer the water from the bucket to the tank, allowing for more control and minimizing disturbance.
After the water is added, you may need to adjust the décor to ensure everything is in its proper place and to maintain a pleasing and safe environment for your aquatic friends.
Why Fish Breathe Heavily After Cleaning
Heavy breathing usually signals a sudden change in water quality—temperature, pH, or hardness.
Tips to Reduce Stress:
Test tank and tap water; match pH and temperature closely.
Add new water slowly.
Use dechlorinators for chlorine and chloramine.
Consult an aquatic specialist if drastic changes occur.
These steps help keep your fish healthy and stress-free.
Wash Up After Cleaning
Always wash hands and arms thoroughly after handling aquarium water, decorations, or equipment. This removes bacteria and cleaning residues and ensures safety before touching electrical equipment.
How to Prime Filtration Systems After Cleaning a Fish Tank
Once you’ve completed cleaning your fish tank, it’s essential to ensure your filtration system is primed for optimal performance. Here’s a straightforward guide to getting your filters ready:
- Hang-on-Back Filters: Start by pouring some aquarium water back into the filter’s larger reservoir. Grab a cup and gently fill it with tank water. Slowly pour this into the base of your hang-on-back filter. This ensures that the pump can function smoothly when plugged in.
- Canister Filters: These systems often come with a specific priming mechanism. Follow the manufacturer’s instructions to activate it. If no priming mechanism exists, you’ll need to fill the intake tube manually with water to assist the filter in starting its process.
- Sump and Other Filtration Systems: If your system uses a sump or similar setup, ensure that any valves you closed during the cleaning process are reopened. Pour tank water as needed to restart the flow within these systems.
After you’ve primed your filters, plug them in and adjust the flow settings to suit your tank’s requirements. Monitoring the filtration system for a few minutes ensures everything is running smoothly. Take this time to also watch your tank closely. Observe your fish to make sure everyone is behaving normally after the water change—look for signs of stress or unusual activity. Listen for any odd sounds from your filtration system as it starts back up; a steady hum usually means things are working as they should. This brief check-in helps catch potential issues early, so your aquatic environment stays safe and healthy.
Common Fish Tank Issues After Cleaning
Noisy Filter: Usually trapped air—let it run or tilt gently to release bubbles.
Stressed Fish: Rapid breathing may indicate water chemistry changes. Match new water to tank’s temperature and pH; test water and seek expert help if needed.
Algae Growth: Some algae is normal. Focus on excessive areas, reduce overfeeding, and limit sunlight if it becomes a problem.
Following these tips keeps your aquarium healthy and stress-free.
How Often Should You Clean a Fish Tank?
It is important to clean a fish tank regularly to maintain water quality and prevent the spread of disease. Fish excrete ammonia, which is toxic to them, so it is important to remove this waste product from the tank.
The frequency of cleaning will depend on the size of the tank, the number and type of fish, and how often you feed them. A good rule of thumb is to clean the tank about once a week.
Replacing Filter Media
Replace only ¼–⅓ of filter media at a time, when it’s breaking down, to preserve beneficial bacteria. Rinse media in tank water, not tap water. Reusable sponges can last months, and used filter water makes great plant fertilizer.
Tips for Keeping Your Fish Tank Clean
A fish tank can be a beautiful addition to any home, but it’s important to keep it clean. A dirty fish tank can lead to a number of problems, including sick fish and bad water quality.
Here are some tips for keeping your fish tank clean:
1. Do a partial water change every week. This means removing about 20% of the water from the tank and replacing it with fresh, clean water.
2. Vacuum the gravel to remove any debris and waste. You can do this with a gravel vacuum or by carefully siphoning the water into a bucket and then back into the tank.
To get the best results, press the end of the siphon into the substrate, allowing the gravel or sand to move about 1/4 to 1/3 of the way up the tube. Then, gently pull the siphon up to break the siphon. This technique ensures the substrate falls back down while the loose debris gets efficiently sucked up through the hose.
Important Tips:
- Water Management: Avoid removing more than 50% of the tank water at a time. This helps prevent sudden changes in temperature and pH levels, keeping your fish healthy.
- Watch the Bucket: Keep an eye on the bucket collecting waste water. When the water level reaches within 3 inches of the top, it’s time to pull the siphon out to avoid spills.
- Fish Safety: Your fish can remain in the tank during this process. Just monitor them closely to ensure they aren’t accidentally caught in the siphon.
By following these steps, you’ll significantly improve your tank’s water quality, ensuring a clean and healthy environment for your aquatic friends.

3. Clean the filter according to the manufacturer’s instructions. This will help remove any build-up of waste and keep the water flowing properly.
4. Wipe down the glass of the tank with an algae pad or sponge to remove any algae growth. Be sure to do this on both the inside and outside of the glass.
When selecting your cleaning tool, it’s important to choose one that matches your tank material to avoid damage:
- Acrylic Tanks: Use a scrubber specifically designed for acrylic to prevent scratches and a hazy appearance. Acrylic is more delicate and can be easily marred by abrasive tools.
- Glass Tanks: While glass is more resilient, it’s still wise to use a suitable scrubber that’s gentle yet effective for removing debris without leaving marks.
If you’re unsure about the material of your tank, it’s safer to opt for a scrubber that is acrylic-safe to ensure the longevity and clarity of your aquarium.
5. Perform a thorough cleaning of the entire tank every few months. This includes removing all of the water, cleaning all surfaces, and vacuuming the gravel again.
