Tetra Whisper 4 Gallon Internal Submersible Water Filter

The submersible filter includes a 3-stage filtration system with a dual-sided Bio-Bag mesh, which catches debris and fish waste while the activated carbon absorbs odors and discoloration. The bio-scrubber features an anti-clog design for convenient and easy maintenance. The bio-scrubber also has a solid back, which pushes the water making it flow evenly over the bacteria-rich bristles for supreme performance. This filter is compatible with Tetra Bio-Bags for easy and reliable maintenance.

Why We Love It:

• Features a submersible filter with a quiet, convenient, 3-stage filtration system—chemical, biological and mechanical.
• Dual-sided Bio-Bag mesh that catches debris and fish waste with an activated carbon that absorbs odors and discoloration.
• The bio-scrubber’s solid back allows the water to flow evenly over the bacteria-rich bristles for best performance.
