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). Since 1951, Tetra has developed the world’s most comprehensive body of fish food knowledge, and fishkeeping enthusiasts have looked to the brand for products and solutions that add ease and beauty to their home. Whether you're an experienced hobbyist or just starting out, Tetra has everything you need – from a large variety of quality fish food and innovative equipment to test kits and decor.

  • 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

  • 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.

  • 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.

Good filter all around. Quiet and powerful. Easy install, usage, and maintenance. I'm glad I took a chance on this one.

  • They really are quiet
Size: 20-Gallon
I bought two as secondary power filters to assist my main 120-gallon filter. I was concerned about noise, but they're surprisingly quiet. I would definitely recommend the WHISPER IQ line. They were easy to set up and worked perfectly right out of the box.

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.

  • Decent Filter for good price
Size: 10-Gallon
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!
