Description

The Tetra Whisper IQ Power Filter with Stay Clean technology keeps aquarium water clean and clear. This quiet filter contains a soft barrier between the motor and the filter that serves as a sound shield to minimize noise. The bio- scrubber cultivates aerobic bacteria to remove toxic ammonia and nitrite, and the smart path spillway oxygenates the water and agitates the surface. With a self-priming, submerged motor and adjustable intake to fit your aquarium’s needs, the Tetra Whisper IQ Power Filter is perfect for use with both freshwater and marine fish. Works with easy-to-change Tetra Whisper Bio-Bag Filter Cartridges with Stay Clean technology – helps reduce buildup on aquarium glass, bind small dirt particles to make them easier to filter and stabilize pH levels to prevent crashes, meaning easier aquarium maintenance for you. Tetra Whisper IQ Power Filters are available in a range of sizes to fit your aquarium. This Tetra Whisper IQ 20 Power Filter treats aquariums up to 20 gallons (130 GPH). Convenient color coding makes it simple to choose the correct size replacement cartridge – use with size large Tetra Whisper Bio-Bag Filter Cartridges (blue packaging).

    • Good little unit.
Size: 10-Gallon
I liked that this filter was adjustable - The part that goes into the water that suctions the water up can either be shorter or taller. For our 10 gallon tank, we used the shorter one. The filter power is adjustable as well. We just have a beta in there so we keep it on low, seems too powerful in the higher settings. I'd say for being on the cheaper side, it was a good value for our money. Its as quiet as a filter can be i guess lol ... show more

    • Great product easy set up
Size: 45-Gallon
It took me less than five minutes to set up about the easiest filter I ever set up. It was ridiculous. If you think about buying it, I’d buy it if I were you it’s a good product. It’s working on my tank just fine. I got a 50 gallon tank and man. Is it doing a good job and did I say it was easier to set up? it was easier than you think. ... show more

    • BEST FILTER FOR BETTAS
Size: 10-Gallon
Review Image by Catsofmany
Review Image by Catsofmany
I bought two of these filters despite a couple negative comments. I've had aquariums for 40 years with many different filters. I currently have a 5, 10, 20, 30, 55 and a 120 for tanks. The 10 gallon tank houses 2 Betta fish with a tank divider. One Betta lives with 2 cherry shrimp but the other is too aggressive to add tankmates. I run a filter on each side. Finding a filter that didn't blow the fish across the tank has been difficult. I've tried a few small ones but they failed to keep the tank clean and the filter cartridges were only an inch wide. I decided to take a chance and I haven't been disappointed. Granted, it's only been a few days. The adjustable water flow is perfect for the Bettas and shrimp. As you can see in one of the pictures, one shrimp likes to sit inside the spillway and obviously not a strong current coming out of the filter. The tank cleaned up beautifully in 24 hours. I did put the inch wide filter cartridge from the old filter into the new filter along with the new filter cartridge for the beneficial bacteria. The Tetra filter is super quiet, appears to be easy to clean and intake strainer is small enough not to suck up the shrimp. The other issue I've had with other filters is failure to prime when our electricity blinks which happens a lot in our town. The Tetra is self-priming so I no longer have to worry. I like that it also has a bio-scrubber (the green basket that cultivates beneficial bacteria). I certainly will update if there are any problems. UPDATE: 16 days...The filters are keeping the tanks clean and the self priming has been wonderful during the last power flickering. The only problem I had is the filters are just a bit too wide for my glass top to sit as far back as it needs to go. Using a pair of snips, I put a small notch into each side of the filter now allowing my glass top to slide into place. ... show more

    • Probably just user error
Size: 45-Gallon
My tank is taller than an average 40 gallon tank so this just barely works for my fish tank struggled to get it together and working, but I’ve had no issues since installing. It works pretty well so far.

    • Works for goldfish
Size: 30-Gallon
If you have goldfish go up in size for your filter. This brand is my go to for fish tank filters but goldfish poop a LOT and need way more filtration than regular fish so I went up in size and its been perfect.

    • Good product, except…
Size: 30-Gallon
Product appears to be working. However, when it was unpacked from the box, the part where the motor lies was/is very loose and looks like it could come apart if not very careful.
