Tetra Whisper IQ Power Filter, 175 GPH, with Stay Clean Technology, 30 Gallons

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.

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.

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.

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.

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.

I love my whisper filter! Not because of the amazing job it does. I was finally able to throw away my air pump & sponge filter. I switched to sponge because I am cheap. I forgot what it's like to not have an angry beehive in my room. It's been years since I've had quiet. I will never go back to a sponge filter. I can hear when my pets are into something in the living room and can stop whatever they were doing. When I bought replacement filters my Ai said I could not adjust the flow rate of water and would have to craft a baffle for my 30gallon whisper IQ. YOU CAN CAN ADJUST THE FLOW RATE! If your Ai says different......just don't ask it lol. It's a great machine.

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!
