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).

  • Perfect replacement for an old unit that no longer works.
Size: 30-Gallon
I’m using this on a 30 gallon aquarium. It’s replacing a unit that worked for many years, until the impeller broke a couple days ago. Assembling this one and getting it in place was easy. I had it up and running in no time at all. It’s very sturdily built, runs quietly and keeps the water clear. The price was competitive for power filters of this type. ... show more

  • Tried and true
Size: 60-Gallon
This is my second Tetra IQ filter. My first one lasted about ten years and is still running strong on my 55‑gallon tank. Recently it started making a light clicking noise, cleaning helped, but I took it as a sign that it was time for an upgrade. This new version is even better. The redesigned cover prevents splatter and stops calcium from building up on the lid, and it runs noticeably quieter than the older model. I like it so much that I’m ordering a second one for the other side of the tank. I keep African Mbunas, and they’re a messy bunch, so strong, reliable filtration is a must. This filter definitely delivers. ... show more

  • Tetra Whisper 20 Gal Filter
Size: 20-Gallon
I am so glad to have a second filter. They do a good job keeping the water clean and not cloudy. It's like a little waterfall when you allow the water to go down an inch or two. Also it is nice and quiet. The flowing water sounds nice if you don't fill the tank to the brim. Love the overnight , free delivery. ... 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.

  • Wonderful Filter for your Aquarium
Size: 10-Gallon
I have been using this filter for months, and it is amazing. Cleans and filters my water perfectly. It is easy to clean and has good studiness. It isn't loud and worth the money. The cleaning power is great for the price. Has a good calming effect and builds sturdy.

  • 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

  • Quiet filter and easy setup
Size: 30-Gallon
The media could not be loaded. Set this up on my tank and the installation was pretty simple. Once it started running, I was surprised how quiet it actually was compared to older filters I’ve used before. Water stays clear and the flow is steady without being too aggressive for the fish. It does need regular cleaning like any filter, but overall it works well and keeps maintenance easy. Good option if you want something simple, quiet, and reliable for everyday use. ... show more
