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).

    • 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

    • Quiet, efficient, and reliable filter
Size: 45-Gallon
The media could not be loaded. This filter has worked very well in my aquarium. It is easy to install, operates quietly, and helps keep the water clean and clear. The water flow is steady without disturbing the fish, which is very important to me. Overall, it is a reliable product that performs as described. I would recommend it for small to medium-sized aquariums. ... 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.

    • Strong flow and very quiet. Lightweight too.
Size: 45-Gallon
I have only had mine a few days, and one of them for even less time than that, but the water flow compared to my old ones is fabulous. They are so quiet! And they make such nice water sounds. My bristlenose plecos love a strong flow and lots of bubbles, and these Tetras provide both. I have two of these filters on my 56 gallon planted tank, minus the included carbon filters (I use mesh). I really hope these last a while; they are superior so far. Update: Been using two of these filters for 3-4 weeks now and they are amazing. The intakes have the strongest pull I have ever seen, and the filters are still so blissfully quiet, providing the beautiful trickling water sounds of a creek or stream. AND THEY ARE SO EASY TO CLEAN! ... show more

Filter quality is excellent, looks good when installed, perfect for my 10 gal tank, good size, very calm and silent. Reducing my span of cleaning. Monies worth.

    • 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

    • Low price filter for smaller tanks
Size: 10-Gallon
It’s very quiet but can make a bit of vibrational noise if the cover is misaligned. No big deal. You can just readjust it. Maintenance is very simple. The siphon self starts after you power it up, so there’s no need to fill it with water beforehand. There’s also plenty of room in the canister for media of your choice. The water flow is strong initially, after a filter media change, but after a few weeks of use, it tends to slow down to a near drip, especially if you have a lot of sponges, floss or carbon in there. Its main drawback, imo, is its size. It’s bulky. I have it hanging on the back of a tiny 5 gallon nano tank and it looks a little out of place in relation to the small tank. Otherwise, decent HOB filter for small aquariums, at a very low price . ... show more
