About this item

The Tetra Whisper 10-30i Power Filter is a reliable and convenient filter alternative for many types of aquariums. This Aquarium Power Filter mounts to the inside of the aquarium, allowing the tank to remain flush against the wall for saving space. The underwater motor also allows this Fish Tank Power Filter to run in soothing silence. The Tetra Whisper Power Filter offers comparable performance to an external aquarium power filter, but is able to be adjusted to high or low water levels with mounting suction cups and/or brackets. In addition, this power filter adds extra versatility because it can function in as little as 2 inches of water or in tanks as large as 30 gallons. This Fish Tank Power Filter comes with one pre-assembled Whisper filter cartridge.

These are cool filters, the water outlet design makes for truly quiet operation. Most filters make a splashing sound when the water comes out. With this filter the water slips into the tank without disturbing the suface tension. This is a big plus for planted tanks! The pump is completely submeged too so no noise there either. Operates in as little as 2" of water, like a turtle tank would have. The filter pad is genius, it's built so you can open it and replace carbon. Rinse it off and it's like new, you hardly ever have to buy new filter pads. Very affordable in the long run and a decent price to begin with. Oh and the pump itself can be removed and used independently as a fountian pump. I like these :)

I currently use this filter on a 30 gallon tank with two turtles in it. It's nice because it does not need to hang off the side of the tank, you can use the suction cups to place it in almost any water level as long as the vents are under water. The water was getting cloudy at the time i put it in and within a few days it was back to being crystal clear. The replacement filters are easy to change, i also found out that they are the same filters as petsmart brand topfin filters. This makes shopping easier and if you cannot get to a walmart the topfin is cheaper than tetra filters at a specialty store.

I was having a major algae problem in my tank, I didn't want to use the drops cause they can kill the shrimp & a few other bottom feeders! I bought this thing, it works like a charm! No need for any pump! And, the best part, it is super quiet & doesn't suck up your smaller breeds of fish! Even works well, if your female Guppy is having babies! Only thing the little babies need to worry about now, is the parent fish!
