Product Information
Full details
The Eden Micro Aquarium Filter 304 is designed for hobbyists managing small aquatic environments, including goldfish bowls, micro tanks, and turtle enclosures up to 25 litres. It provides essential mechanical and chemical filtration in a footprint-conscious design that maximizes swimming space for your aquatic pets. While it is highly efficient for its size, potential users should note that its capacity is strictly limited to 25 litres, making it unsuitable for larger community tanks or heavy-stocking scenarios.

FAQs
Can this filter be used in saltwater tanks?
While primarily designed for freshwater, the materials are robust; however, saltwater environments are often more demanding and may require more frequent maintenance.
How often should I change the filter media?
The sponge can be reused for several months if washed carefully. The activated carbon cartridge should be replaced every 4-6 weeks.
Is this filter safe for shrimp?
Yes, but ensure the intake is not drawing in baby shrimp, which can happen with high-flow pumps.
What is the warranty period?
The product comes with a 3-year guarantee from the manufacturer.
Can I adjust the flow rate?
The Eden 304 is designed for a consistent flow of 240 lph; there is no manual dial to restrict flow, so ensure it is suitable for your specific species.
Does this filter aerate the water?
By positioning the outlet near the water surface, you can create surface agitation, which helps with oxygen exchange.
Troubleshooting
Reduced water flow output
Clean the mechanical foam sponge and check the intake for blockages caused by plants or debris.
Increased noise levels
Check that the impeller is seated correctly and clear of grit; ensure the filter is not vibrating against the glass.
Water appears cloudy
The activated carbon may be exhausted. Replace the carbon cartridge and ensure you are not overfeeding your animals.

Setup, Compatibility & Care
To set up the unit, ensure the filter is securely attached to the interior glass using the provided suction cups. Before initial startup, rinse the sponge and carbon cartridge in de-chlorinated water to remove manufacturing dust. For maintenance, rinse the sponge in a bucket of tank water (never tap water, as chlorine kills beneficial bacteria) every 2-4 weeks depending on the bio-load. The activated carbon cartridge should be replaced every 4-6 weeks to maintain chemical absorption capabilities. Ensure the water level stays above the intake at all times to prevent the motor from running dry.
