Tetra Whisper EX 70 Filter For 45 To 70 Gallon aquariums, Silent Multi-Stage Filtration, WHITE

The media could not be loaded. I purchased 2 of the Whisper EX30 units for my 33 gallon long tank. Both work flawlessly and quietly. I even took a short video of them. Finally the air circulation system in the building shut off so I could tape this (Very rare, building owner doesn't like people suffocating in the building and dying I guess), both of these units run quietly enough together that the little bubbler is louder then them. The video is filmed in dead silence in the middle of the night. TV easily drowns these out. They do make a little hum, not a big deal, they all hum a little. These truly are whispers, if yours isn't, talk to someone about it and get it replaced, you have a defective unit. Neither has given me any trouble, both work the same and are very reliable. You can also see the water is crystal clear, my water is never any worse then it is in the video, even right before a bi-monthly water change.Only thing that bothered me, not enough to take away a star, was it is a little snug on the tank, good in some cases, I just like a bit of play because down the road if they ever do start vibrating or such, I could put a thin foam pad between them and the tank and loud pumps go quiet then. Did that with the Aqua-Tech I had prior to these because it screamed like a banshee right outta the box. Seriously impressed with these units though, and fitting snugly is probably a good thing. And by snug I mean, it fits like a glove, no forcing it on or anything, fits right down as it should, but has no play. Like it was machined to fit (On my tank anyhow).PS - Disappointed with the FEDEX guy though, slacker entered delivery attempt when none was made since I was here the whole time, gate unlocked and open. No door tag provided, secretary and surveillance cams saw no sign of him anywhere that day, didn't even drive past. Had to pick this up 2 days later and talked to manager. Disciplinary action took place before I had even left, glad I wasn't that guy, they were really tearing a strip off him.

This filter is amazing, it keeps the tank so clean,

I run a 55gal live planted aquarium and needed a suitable filter as the one that came with my setup was garbage and burnt out in 2 months. This thing does its job in a so-so fashion, realistically all filters are the exact same thing. cheap carbon filters and some plastic shaped wiggly or spiky to do..not a whole lot actually. this thing is only silent when my tank is filled completely to the top. it does NOT have any valve or knob to adjust the suction or the waterfall power which means people have come up with creative ways to silence this filters noise output. As I write this review my tank is down barely 2" which is about where it gets when I add more water and the filter is so loud with water splashing that my pc desktop microphone picks up the sound of the water lol. So if you're looking for a /quiet/ filter in a home office, think again. I've heard some people chop up brillo pads and stuff them in the waterfall to make it quieter but I haven't tried that nonsense out yet. frankly, a product should work as labelled without requiring modifications by users.

So I bought this filter for my 40 gallon tank. I needed something that I thought would over filter my tank, since I do have a variety of fish stocked. Well the 1st filter arrived BROKEN.... so it was tedious to have to wait an additional week to get the replacement sent out. When it finally arrived, I assembled it & cleaned it before I added it to my tank. Once I had it set up I initially thought it was doing a great job until it wasn't. I noticed that the water started to flow less and less, so my thought was maybe it had collected gunk so I'd clean out the filter to make sure the water could flow through.... nope that wasn't the issue. I checked the tube and made sure it was sitting nice and tight... didn't fix the problem. The water levels were at the correct level, since the filter shows a line where it requires the water level to be. I started to feel very disappointed because the price is pretty steep for such a problematic and flimsy filter. I use tetra filters in my other aquariums (I have a total of 6) which don't cause problems; as long as they're maintenance regularly. Anyways, months went by and I kept experiencing issues, by this time my return window had closed. I went as far as switching the type of media I was using, thinking it would have an easier flow, but nothing worked for me. Eventually by October 2024, the filter just stopped working. I took it apart and checked everything and didn't find anything wrong. I let the impeller sit in water for a few days to see if that was the issue and still nothing. When I would plug it in, it didn't even seem to be on. I gave up and tossed it out. This filter really sucked for me. Maybe I just had bad luck and ended up with a faulty one but I won't be buying this type again. For now I've just kept my tank filtering with the sponge filters and have been shopping around for a different filter. So bottom line, I definitely do not recommend this filter. Buy at your own risk...
