EHEIM professionel 3

Large aquariums demand powerful, reliable, and long-lasting filtration that can maintain crystal-clear water even under heavy bioload conditions. Whether you keep monster fish, goldfish, cichlids, planted aquariums, or high-volume community tanks, you need a filtration system that works efficiently, quietly, and with minimal maintenance. This is where the EHEIM professionel 3 series stands above the rest. Representing the highest level of German engineering, this filter is widely recognized as one of the most advanced canister filters ever created.

🌟 The Jewel of Filtration Technology

The professionel 3 series embodies EHEIM’s decades of innovation:

• Exceptional power efficiency

• Industry-leading silent operation

• Massive filter volume

• Integrated safety mechanisms

• Ultra-long service life

• Strong and stable construction

For fishkeepers who demand absolute reliability, this filter is built to perform continuously for years with minimal intervention.

🔄 Revolutionary Triple Hose Adapter

The professionel 3 is the first filtration system to feature a three-hose adapter:

• 2 × suction inlets

• 1 × pressure outlet

This intelligent design ensures stronger water circulation, improved debris removal, and more stable biological filtration—even in tanks up to 1200 litres.

🧰 Designed for Ultimate Convenience

Every detail is engineered to make aquarium maintenance easier and safer:

Self-Priming Suction Aid

Forget manual siphoning! Simply activate the suction mechanism, and the canister fills instantly, letting the filter start without any effort.

Safety Hose Adapter

The hose adapter locks securely and can only be released when all valves are closed—preventing spills and protecting your equipment.

Transport Wheels & Prefilter Tray

Large models include wheels for easy movement.
The removable prefilter tray ensures drip-free transport during cleaning sessions.

🧪 Advanced Filtration Performance

The square canister design provides:

• Higher filter volume

• Better stability

• More space for media

The large prefilter catches coarse waste before it reaches the biological baskets, significantly extending maintenance intervals. Beneath the prefilter tray lie three modifiable filter baskets that can be filled individually based on biological, mechanical, and chemical needs.

🔕 Silent Operation with Ceramic Technology

Using EHEIM High Performance Ceramics, the impeller axle and bearings run with exceptional smoothness, ensuring:

• Whisper-quiet performance

• Higher durability

• Long-term stability under heavy use

For aquariums placed in bedrooms, living rooms, offices, or display areas, this level of quietness makes a major difference.

🔥 Optional Thermo Version (1200XLT)

The Professionel 3 series also offers a thermo model with an integrated heater. This keeps water temperature stable and eliminates the need for a separate in-tank heater—ideal for large aquariums and sensitive species.
