Feature Overview

To further help you get to know the Whisper 10i better, we’ve rounded up the key features that should help you make your mind about it:

80 GPH, 10-Gallon Capacity

As mentioned above and as its name suggests, the Tetra Whisper 10i is a filter made for a 10-gallon tank. With its 80 gph rating, however, it exceeds the recommended 4 times of water turn over per hour. With this, you can be guaranteed that it’s powerful enough for your small tank, and maintains the water levels. 

However, as not all tanks require fast water flow, you should also take into consideration the creatures you’ll be using this filter with. It might not be the best pick for those with very small fishes or live plants. 

3-Stage Filtration

Despite its simplicity, the Tetra Whisper Internal Power Filter is already equipped with a 3-stage filtration system, so you’re guaranteed that it can thoroughly clean the water inside your tank. Despite its small size, it has two media filters available: a Bio-Scrubber cartridge and a dual-sided Bio-Bag cartridge.

The Bio-Scrubber works as a housing for the beneficial bacteria that should be present in your tank to keep the water healthy. The Bio-Bag, provides mechanical and biological filtration as it strains and removes debris as well as neutralizes odors and discoloration. Both the Whisper Bio-Bag and Bio-Scrubber are essential for the filter’s optimal performance, and operates as a very efficient filtration system.

Waterfall-style Outflow

There are no nozzles that need adjusting and positioning with the Whisper 10i. This makes it easier to work with as you don’t have to worry about its configuration all the time. Its open-top design also aerates the water with great ease, helping create a healthy environment for your aquatic pets.
