Why Choose an External Filter?

External filters are a popular choice for aquarists who need powerful and versatile filtration. Positioned outside the tank, these filters maximise space inside the aquarium while offering greater filter media capacity for mechanical, biological, and chemical filtration. External filters provide superior water flow, making them ideal for larger tanks or aquariums with high bio-loads.

Key Benefits of External Aquarium Filters

• Increased Media Capacity: Accommodates multiple layers of filtration media for better water quality and flexibility.
• Efficient Water Flow: Delivers strong and consistent circulation to maintain a healthy and balanced ecosystem.
• Space-Saving Design: Positioned outside the aquarium, external filters free up valuable space inside the tank for decor and aquatic life.
• Easy Maintenance: Many external filters, like the Oase Biomaster range, feature pre-filters for quick and hassle-free cleaning.

Features of External Filters

External filters are designed to offer advanced functionality and user convenience. Key features include:

• Multi-Stage Filtration: Combining mechanical, biological, and chemical filtration to ensure crystal-clear water.
• Quiet Operation: Designed for noise-free performance, ensuring a peaceful environment.
• Customisable Media: Allows you to use various types of media to suit your aquarium’s specific needs.

Choosing the Right External Filter

When selecting an external filter, consider the size of your tank, the bio-load, and the specific requirements of your fish and plants. Larger tanks or those with more inhabitants may require a filter with higher capacity and water flow. Our team is here to provide expert advice to help you choose the perfect filter for your setup.

Maintain Your External Filter for Optimal Performance

Regular maintenance is key to keeping your external filter running efficiently. Clean or replace filter media as needed and check water flow to ensure proper operation. Filters with pre-filter systems, like those from Oase, make maintenance even easier by allowing quick access to debris without disrupting the entire system.
