    • EXTREMELY LOUD and doesn't flow
Size: 10-20 Gallons
The media could not be loaded. This is quite honestly the worst aquarium filter i have ever used! I keep a number of different aquariums, both salt and fresh water, and have used dozens of different filters over the years. One of my favorites in fact, is an old tetra whisper 10 which is so silent you wouldnt even know its running. But this EX20 is all kinds of bad. It flows about a quarter of what is advertised, maybe enough to just barely filter a 5gal tank, and thats only the begining. The noise, oh the aweful noise!!! It vibrates so bad that the whole tank shakes, which in and of itself makes a good deal of noise. So i though, "I'll put a piece of felt under the filter on the edge of the tank." But that didn't solve the problem. In fact, the filter body itself is so poorly machined and constructed, that the vibration causes the filter media holder to rise inside of the housing over time, and then contact the top of the filter, which makes an extremely loud buzzing sound akin to an old alarm clock. That sound, unexpectedly at 3am, will scare the snot out of you! So to solve that problem, i removed the top of the filter housing. Even with the top of the filter removed, and felt underneath, the filter is too loud to use, and doesnt flow enough to filter anywhere near its advertised gph. I would strongly recommend you look elsewhere for your filter needs. I have also attatched a video of this filter running, with felt underneath of it. ... show more

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!! ... show more

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 ... show more
