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 30 Power Filter treats aquariums up to 30 gallons (175 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).

    • Gentle sound/powerful work
Size: 20-Gallon
This is the quietest, most efficient filter I have used in an aquarium. I have tried many others and was shocked when I plugged this one in. It worked quickly to rid the tank of a hazy cloud despite being almost totally silent. Thank you Tetra! Also - easy to assemble!

    • As described
Size: 10-Gallon
Runs whisper-quiet and keeps the water crystal clear—my tank looks spotless after just a few days. The Stay Clean cartridges make maintenance simple, and the flow is powerful enough to keep things moving. The only drawback is size: in my 5-gallon tank it feels bulky, and I had to angle the top to fit. Perfect match for a 10-gallon setup, but a tight squeeze in smaller tanks. ... show more

    • Great Filter Running in a 55 Gallon tank
Size: 60-Gallon
This IQ Power filter is amazing! I’m running it in my 55-gallon tank even though it’s rated for 60 gallons, and it has been going strong for months with absolutely no issues. Water stays crystal clear, and the flow is perfect for my fish. Super reliable and well-built—I highly recommend it!

    • 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.

    • The adjustable flow makes the 10 gallon filter perfect for a fry tank
Size: 10-Gallon
Tetra whisper IQ power filter 10 gallons: I love the adjustable flow. I wanted a hob for my 10 gallon cory fry tank, the sponge filter just wasn’t cutting it on keeping the tank looking clean. The 1st hob I tried didn’t have an adjustable flow and the fry were clearly struggling in the current it created. So I got this tetra filter. I’ve only had it running a few days but so far couldn’t be happier with it. I have it on a medium/low flow setting and it’s perfect for the fry. It was easy to set up. I didn’t use the adjustable intake tube, that would have been too long. Without the intake tube, the intake sits right in the middle of the tank. And a small intake pre filter sponge fits nicely on it, don’t even need to secure it with a zip tie. I cut some filter sponges to fit where the disposable cartridges go. I also love it has an internal pump, why some others don’t have an internal pump is beyond me. It’s not very noisy which is nice also. All in all, the adjustable flow and easy pre filter sponge application/maintenance makes the 10 gallon filter a great fry tank filter in my opinion. I paid $13.99 before tax for it, which seems like a good price. ... show more

    • Great filter.
Size: 45-Gallon
Dead silent and it starts its own siphon. The only time it makes a noise is if I let my water get too low and it starts waterfalling into the tank. But, that's not the fault of the product. I did replace the filter media with a coarse sponge and water polishing filter media, both from aquarium coop, so that I don't have to pay a recurring filter media cost. I also bought a sponge for over the intake. That helps its filtering capacity a lot and keeps shrimps and fry from getting sucked in. ... show more

It fits nice in a 10 gallon tank. Although it can partly broken, it still works perfectly fine in my betta tank and is very quite!
