 Filter cartridge carrierThe Tetra Whisper Power Filter comes with a filter cartridge carrier that keeps your hands clean and eliminates any unwanted drips. |  Timestrip technologyThe Whisper EX models come with Timestrips that tell you when your carbon filter needs to be changed — simply change the cartridge when the Timestrip changes from white to red, indicating the carbon has been used up. Timeslips come free with each filter. All you need to do is press firmly on the button and timing will begin. |
 Maximum oxygenationThe Tetra Whisper EX filter is designed to move your aquarium’s water continuously. The outflow optimizes water oxygenation while the motor operates quietly. |  Can be used in turtle tanksThe Tetra Whisper EX filter can be used in turtle tanks. The water level must stay above the minimum water level line at all times, which means it needs to be within 3-4 inches of the top of the tank. |

Had all kinds of fish tanks for 50 years. Although it’s probably a little bit of a over kill I’ve never had clearer water and the fish are much more lively. Have used the old style whisper filters over the years and they are very quiet and reliable for years unlike the Marineland I’m replacing after 2 years. My Marineland filter always clogged up weekly despite monthly changes and weekly cleanings . Love the new modern look of the ex whispers too.The excellent pricing of the ex whisper on Amazon is why I went with the extra pump. Replacement filters are more money for the ex but I know I’m going to get excellant reliable service for many years. Go with the Whisper.

I’ve only been running this for a day but I LOVE IT. I got the 10 gallon filter as a replacement for my Tetra Whisper 2-10i filter, which became infiltrated with brown algae beyond repair (I’m learning how to do plants…oops). This was for a 10gal with a betta and two Cory catfish.It has a quiet, steady hum, and it sits sturdily in place on the back. The suction is good and the flow is amazing, but will be far too much for most bettas. As some others have said, definitely make sure that the suction cage tube is snug; if the tube comes loose, your fish are exposed to the open pipe leading into the filter’s motor. That’s the one big design flaw about it, unfortunately, but this was a second choice for me anyway (Fluval C2, why must you always be out of stock?!). You could always put a decoration under the suction cage to sort of wedge it in place to be safe; I might do that myself, but it seems fine.My customization techniques:I cut some plastic mesh off of an onion bag and used twine to baste stitch and fit it to the suction piece. That way something prevents my fishies’ fins from being sucked in and injured.As for the flow, I cut a plastic dish scrubber so that it was held in place by the bio scrubber and the rest of it hung down to slow the flow. Its flow is amazingly perfect now. Pics attached if anyone wants to take inspiration from me. 🙂 These adjustments took maybe 10 minutes. Good luck y’all!!

I’ve had my 55 gallon fish tank for a few years now and just recently my original whisper ex70 that came with it started not sucking in or putting out as much water as it should. I tried everything I tried cleaning it I tried making sure it was unclogged everything and it’s still didn’t want to work up to par and was causing my fish tank to be dirtier than it should and causing my fish to be stressed. I decided just to buy a new one and I already know how to use this specific model and have replacement filter inserts for them so I just got the same one. It’s pretty easy to use it comes almost completely set up. When you get it out of the box all you have to do is open the filter packages and put them right back in where they already were. You’re going to want to put it on the back of your fish tank and connect the downstem which is the piece that sucks in the water. It comes with three different pieces so you can adjust the height for the tank that you’re using I didn’t use one of the pieces because I didn’t want it to go down that far. all you do at that point is plugged in. If it doesn’t suck up enough water to fill the reservoir and get started by itself you can simply scoop some water out of your fish tank and put it into the reservoir. When I started it it filled up all by itself and went instantly without any problems. this filter comes with two charcoal filters which are not my favorite of these products because the clip on the top of those holders seems to come apart which makes them harder to replace but you can still do it. I like to take them out and rinse them out every so often and replace them every couple of months. overall my first one lasted me a few years and I’m hoping this one last me a few more

Just got in the mail and set it up! So far so good. It’s not any louder than the one I had before. Actually might be quieter. It’s very good at aerating the water. And the fish seem so happy. Placed in my 10 gallon tank. Hoping for crystal clear water. Its a very nice filter. Has a bio scrubber and a charcoal filter. The top has a litrle lid so you can remove the filter easily.

I had this same filter (purchased from petsmart) and it lasted 5 years. When it finally stopped working I ordered another. Works great on my 25 gallon tank. Quiet and reliable. Filters are not that expensive either if ordered from Amazon (at petsmart they are double the price). Filters are easy to change and this keeps the tank clean.

I bought the larger size (20 gallon) by mistake but decided to keep it and try it out in our 5 gallon tank, it’s super quiet no noise at all and it keeps my aquarium water cristal clear. I put a piece of aquarium filter foam to slow down the flow for my Betta (see first pics) and is working great. He seems relax at peace swimming around without any issues. I change the filter every 6 wks just because i have the fliter cartridges, all the water tests come out clear, all good. Highly recommended, i like it a lot!I ordered the same filter but smaller size (for a 10 gallon) for my 3 gallon tank and is working great too, silent and durable! I also put a piece of filter foam to slow the water flow, see pics. Highly recommended
