The Eheim Professionel 4+ 350 (2273) is ideal for aquariums from 45 to 95 gallons.
The Eheim Professionel 4 series are the leading high-end canister filters on the market. The new pre-filter design, with easy access just under the pump head, traps dirt at the top of the filter, making regular maintenance easier. It also significantly extends intervals between biological media cleaning. Simply rinse the pre-filter and change the fine filter pad, and leave the biomedia in the bottom baskets undisturbed, thereby extending the life of the filter.
Features:
- Energy efficient
- Pre-filter for easy intermediate cleaning
- Integrated self-priming button
- Exceptionally quiet
- Multiple media baskets
- Includes all media
- 3-year warranty
- Made in Germany
- For both fresh and saltwater aquariums
Description of the Filtration Process
Aquarium water enters the filter through the intake tube and flows downwards to the pre-filter tray. Reversing direction, water then flows up through the first-stage pre-filter foam, trapping the majority of the large debris at the top.
The water is then pulled down an internal tube to the bottom of the canister where it is dispersed and suctioned up through the second-stage multi-purpose media baskets, at which point it passes through the biological layer of Eheim Substrat Pro. This media contains thousands of square feet of nitrifying bacteria which biologically break down aquarium toxins.
In the third stage, water is pulled through the fine white filter pad, performing the final water polishing by trapping the finest dirt particles. The clean, filtered water then flows back out into the aquarium.
