Tetra Whisper IQ Power Filter 20 Gallons, 130 GPH, with Stay Clean Technology

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.

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.

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.

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.

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.

Super quiet and dependable

This filter is very quiet and moves a lot of water. The water flow adjustment is easy to access but the change in flow is minimal so be aware of the water flow to match your tank. I had a filter sleeve from my previous Tetra filter so I used it instead of the Clear Water one included in the box so I can't comment on it but I'm hesistant to add something chemical into my tank. The one problem I have is that it leaks on the intake area, not a lot but it shouldn't leak. This is probably an individual product flaw so I won't lower my rating - 4 stars because it is very quiet but I wish there was more control to the water flow.

Best filter I have bought in decades, provided it endures. The flow control was tricky, the difference between trickle and waterfall is a tiny move of the dial, but just having flow control is the main point. It's VERY quiet. I hear the trickle of water, not the filter. The filters themselves are sold as kits you can make for very cheap. The flow control/suction goes pretty fast, i suspect you could use this for a 50G freshwater tank in a pinch.

Product is very good but not working in UAE

Lo utilizo en una pecera de 40L, así que me queda super sobrado. Mega silencioso, poco ruido, poca vibración. Casi no se nota que está. Recomendada 👍🏻

Comparado con otros filtros del mismo tamaño, mueve un buen volumen de agua con muy poco ruido, funciona de nuevo si se va la luz. Muy buena calidad y recomendable.

Could not use!!!
