Tetra Whisper Internal Aquarium Power Filter with BioScrubber

If you don't mind getting the original foam filters and not the updated BioScrubber filter, they work like normal. They self start back up if you have a power outtage, no need to prime back up. All ten are working perfectly as new and as long as the intake slots are submerged with water, they are strong enough to pull water the rest of the way up to keep water flowing if you want to do a partial water change and not have to turn them off. Great for fish with high oxygen requirements. I ordered ten of the Tetra Whisper Internal Aquarium Power Filter with BioScrubber, 20-40 gal. All ten of them had the original foam filters instead of the BioScrubber filters.

All ten of them had the original foam filters instead of the BioScrubber filters. I had a large shipment of fish show up the same day my filters showed up, so I couldn't risk returning them and trying to find ten replacements locally on the same day. I contacted chewy customer service and they could not send me the missing BioScrubbers to complete my order, but wanted me to do a return and reorder. This was not feasible due to my fish needing them immediately. Just bad timing for getting not what I ordered. … more

I think it's just a cheaper alternative for smaller tanks, it's definitely very quiet no problems there. But, it doesn't keep the water clean very long we also started noticing bubbles almost like soap but kinda like a foam as well not sure what that's about. Definitely will be looking into another one that will stay clean a bit longer and be a bit more effective. I've seen other say it keeps it clean for quite a while but I've changed the filer and had to clean the whole tank more than three times in one month and, it's only a GALLON fish tank. You'd think a 5 to ten filter would keep always a gallon cleaner than it does.

Chewy offers great prices and fast shipping. The closest pet store to where I live is about 25 minutes away and it's very small so the prices are very steep and she's prices are almost half of what I would pay after driving all that way. They have a bigger selection and very fast shipping it's definitely worth it and I would definitely recommend this site for anything that's shippable!!

I've had this for about a week or so in my goldfish tank and it seems to be doing ok. The suction cups it came with are not very strong and if bumped they fall off so I recommend using the hang on the back attachment if you can. The current isn't overly strong for my baby fancy goldfish but it is definitely not quite. I also have a large sponge filter in the tank to help because goldfish are so messy and this filter is way louder than the sponge and air pump. If you need the extra water agitation and filtration this is a pretty good option, but if you are looking for a filter that makes very little noise I would not recommend this one.

It does filter but I have found trouble with the way is hangs on the tank and tends to fall off the side of the tank frequently.I have also found it it causes a lot of micro bubbles in the tank if not hanged on at a specific angle but when hanged at said angle and when stays on side of tank it does filter the water well and does it’s job.

I bought the large filter about a year ago and have been using it ever since. What I like is how quiet it is, thus living up to the Whisper name. Cleaning the filter and media gets mixed reviews, however. The bio scrubber lives up to its name and function. A simple shake in used aquarium water is sufficient to clean the gunk off without harming the bio bed. The filter pad gets rinsed off in the sink. The gunk goes down the drain and leaves some biological filtering. Getting to the filter impeller to clean that out to maintain water flow requires taking the entire filter out of the aquarium to remove the screws holding the bottom together to access and clean the impeller and compartment.

I find this a bit unhandy. I have used pressurized water to clean out the gunk using backflow and that works to a point. My advice is be aware that this filter may need more effort to clean than a smaller Whisper unit. All in all, i like the filter, but believe the design could be much improved for ease of cleaning. … more

I had an older model of this filter and after 6 months it stopped working. I purchased a new one, expecting it to work just as well as the original had in the beginning. I even upgraded to one for 20-40 gallons, even though my tank is only 20. After a full 24 hours, my RES's water is cloudy and looks exactly the same as it did before the new filter went in. I'm so disappointed and now i have to try to find something else until I'm able to get yet another filter delivered. I love Chewy, but this filter is no good.

This filter does an excellent job! Before I did water changes monthly or sooner when the water looked dirty. With this filter the water still looks clean at changing time.

This filter was discounted when I bought it. Definitely worth the price. It's so quiet, I'm not sure how silent some of these reviewers are expecting a filter to be. Especially considering that my tank is not completely full, this is supposed to cause the filter to be louder- but it's still nearly silent. I must say, I didn't realize how bulky this filter was going to be. It will work great for now but I'll be looking for something more minimal in the future. Packaging says it cleans up to 125 gallons per hour, I have a 5 gallon tank. Instructions were incredibly easy considering this is my first tank. I did call the manufacturer because I was concerned about something that I was assured is completely This filter was discounted when I bought it. Definitely worth the price.

It does say not to use with sand, but it seems to be working fine. I assume this means wait for the sand to settle before running the filter. … more

This filter is so quiet and the guppies honestly seem to enjoy hanging out in the stream of it. It is doing a good job, too!! What a relief, we were having some household tension over the volume of my last aquarium filter.
