Tetra Whisper Power Filter 30

Whisper Power Filters are appropriate for every size aquarium, they provide the three types of filtration that your aquarium needs:

• Mechanical Filtration -- To remove particles such as uneaten food, bits of plants, fish waste, etc., from the water
• Biological Filtration -- To provide for the growth of a colony of beneficial bacteria that will eliminate harmful toxins in the water
• Chemical Filtration -- Activated carbon removes compounds that cause odors and discoloration of the water

Designed for ease of use, Whisper Power Filters use Bio-Bag filter cartridges for mechanical and chemical filtration. The disposable Bio-Bags remove waste particles, discoloration and odors from aquarium water. Bio-Bags are easy to change, making it easy to maintain clear aquarium water.
