aqueon filter not working Common Issues and Quick Fixes

What is an Aqueon filter?

Aqueon filters are a popular choice among aquarium enthusiasts for maintaining clean and healthy water in their tanks. These filters come in various types, including hang-on-back filters, canister filters, and power filters, making them suitable for different aquarium setups. Regardless of the type, Aqueon filters all serve the same critical purpose: to circulate and filter the water in your aquarium, ensuring it remains free from harmful impurities.

Why is it important to have a working filter in your aquarium?

Maintaining a working filter in your aquarium is essential for several reasons. Firstly, it helps to remove waste, excess food, and other debris from the water, preventing it from becoming cloudy and foul-smelling. Secondly, a filter provides oxygenation by agitating the water’s surface, promoting a healthy environment for your fish. Lastly, a filter also plays a vital role in biological filtration, which is crucial for breaking down harmful substances like ammonia and nitrites, keeping your aquatic pets safe and sound.

Common problems with Aqueon filters

While Aqueon filters are generally reliable, like any mechanical device, they can encounter issues over time. Some of the common problems you may face with your Aqueon filter include:

  • Aqueon filter not working: When your filter simply refuses to turn on or run, it can disrupt the filtration process and pose a threat to your aquarium’s water quality.
  • Aqueon filter not pumping water: If your filter is running but not moving water efficiently, it can result in poor circulation and inadequate filtration.
  • Aqueon filter making noise: Unusual noises coming from your filter can be annoying and may indicate a problem with the impeller or other components.
  • Aqueon filter leaking: Water leaks from your filter can not only make a mess but also damage your aquarium equipment and surroundings.

In this guide, we will explore how to troubleshoot these common issues and get your Aqueon filter back to optimal performance.


How to determine if your Aqueon filter is not working properly

Before diving into troubleshooting, it’s essential to identify whether your Aqueon filter is indeed experiencing issues. Here’s how you can determine if your filter is not working as it should:

  1. Inspect the water flow: Observe the water flow from the filter’s output. It should be steady and not obstructed. If the flow is weak or irregular, it’s a sign that something might be wrong.
  2. Listen for unusual noises: Pay attention to any unusual sounds coming from the filter. Grinding, rattling, or clicking noises can indicate problems with the impeller or other moving parts.
  3. Check for leaks: Examine the area around the filter for any signs of water leakage. Even a small leak can be indicative of a larger issue.
  4. Monitor water quality: Keep an eye on your aquarium’s water quality. If you notice a decline in water clarity, an increase in ammonia or nitrite levels, or if your fish appear stressed, these could be symptoms of filtration problems.

Common causes of Aqueon filter problems

Understanding the root causes of Aqueon filter problems is crucial for effective troubleshooting. Here are some common issues and their potential causes:

  1. Power supply issues: If your filter is not turning on, check the power source. Ensure that the outlet is functional, and there are no tripped circuit breakers or blown fuses.
  2. Clogged filter media: Over time, filter media can become clogged with debris, reducing water flow and filtration efficiency. Regularly cleaning or replacing filter media can prevent this issue.
  3. Dirty impeller: The impeller is a critical component responsible for water circulation. If it becomes dirty or obstructed, it can lead to reduced flow or noisy operation.
  4. Airflow problems: Some filters, like hang-on-back models, require proper priming to expel air and establish water flow. Insufficient priming can result in poor filter performance.
  5. Mechanical damage: Accidental damage to filter components, such as cracks in the housing or impeller shaft, can lead to leaks or operational issues.

How to fix common Aqueon filter problems

Now that we’ve identified the potential issues, let’s explore how to address them:

1. Aqueon filter not working

  • Check the power source: Ensure the filter is plugged in correctly and that the power outlet is functional. Replace any blown fuses or reset tripped circuit breakers if necessary.
  • Inspect the power cord: Look for any visible damage or fraying on the power cord. If you find any, replace the cord immediately to avoid electrical hazards.

2. Aqueon filter not pumping water

  • Clean or replace filter media: If the water flow is weak, clean or replace the filter media. Over time, debris can accumulate and reduce the filter’s effectiveness.
  • Clean the impeller: Remove the impeller assembly (consult your filter’s manual for guidance) and clean it thoroughly. A dirty impeller can cause poor water circulation.
  • Check for obstructions: Inspect the intake and output tubes for blockages. Sometimes, debris or algae growth can hinder water flow.

3. Aqueon filter making noise

  • Inspect the impeller: Noises may be due to a dirty or damaged impeller. Remove and clean it carefully, ensuring it is reassembled correctly.
  • Tighten loose components: Check for loose or misaligned components within the filter. Tighten or realign them to eliminate noise.

4. Aqueon filter leaking

  • Inspect for visible damage: Carefully examine the filter housing and connections for cracks or damage. If you find any, consider replacing the affected parts.
  • Check seals and gaskets: Leaks can also occur due to damaged or deteriorated seals and gaskets. Replace them if necessary.


While troubleshooting and fixing Aqueon filter problems are essential skills for aquarium enthusiasts, it’s even better to prevent issues from occurring in the first place. Here are some preventive measures:

  • Regular maintenance: Clean and maintain your filter and its components regularly. This includes cleaning or replacing filter media, checking the impeller, and ensuring proper airflow.
  • Monitor water quality: Keep a close eye on your aquarium’s water parameters. Regular water testing can help you detect issues before they become severe.
  • Follow manufacturer guidelines: Always follow the manufacturer’s instructions for installation, operation, and maintenance of your Aqueon filter. This will help prolong its lifespan.
  • Avoid overloading: Don’t overload your filter with excessive fish or overfeeding. This can lead to increased waste production and strain on the filtration system.
