The All Pond Solutions EF Filter Range vs the Classic EF Series

Reliable Filtration, Refined for Today’s Aquariums

At All Pond Solutions, we’re proud to offer two exceptional lines of external aquarium filters the classic EF series and the EF filter range, an enhanced evolution designed for modern fish keepers. Both deliver powerful multi-stage filtration, but the EF range introduces subtle improvements that make maintenance simpler, performance stronger, and durability longer lasting.

Built on Proven Performance

Both filter ranges share the same dependable multi-stage filtration system, combining mechanical, biological, and chemical filtration through layered media baskets. Each unit comes supplied with ceramic rings, bio-balls, coarse foam, and fine floss pads to effectively trap waste and purify water.

Water is drawn into the filter via an inlet tube, passes through the filter media, and returns through an outlet spray bar to oxygenate and circulate your aquarium water. As external filters, both ranges save valuable tank space while offering generous media capacity, making them ideal for medium to large aquariums.

The Key Differences Between the EF and Classic EF Models

The EF range takes everything customers love about the original EF filters and refines it with practical upgrades that make daily aquarium care even easier.

Notable Improvements

• Simplified Priming System – Easier, smoother, and more consistent, reducing setup time and simplifying restarts after cleaning.
• Reinforced Filter Body – Stronger and more durable for long-term use, ensuring resistance against pressure and wear.
• Improved Marine Compatibility – Upgraded fittings for better longevity in saltwater environments.
• Refined UV Steriliser Design (on ‘+’ Models) – A new magnetic safety system replaces mechanical parts, improving reliability and extending component life. An enhanced on/off indicator light makes operation clearer.
• Extended Two-Year Warranty – All EF range filters now include a full two-year warranty, offering added peace of mind.

What Does the “+” Mean?

Any model featuring a ‘+’ symbol, such as EF2+ or 1400EF+, includes a built-in UV steriliser.
This UV unit helps to control algae growth and eliminate harmful bacteria, keeping your aquarium water cleaner and healthier.
Filters without the “+” perform the same mechanical, biological, and chemical filtration but without the added UV sterilisation — ideal if your setup doesn’t require it.
