Tetra Whisper Internal Aquarium Power Filter with BioScrubber

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.

I did call the manufacturer because I was concerned about something that I was assured is completely normal. Over all great product so far, I highly recommend it. 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

Silent, slow and steady water current. suitable for my betta fish BUT it’ll be great if it didn't have a flimsy top cover piece. I woke up this morning to my entire table soaked and game console damaged. for 2 hours I was figuring out if it was the tank that was cracked but to my surprise I notice sometimes the water will make pressure under the top piece, go over and pass the clip that holds it to the glass and over. I will advice anyone to have the filter lower then the clip to avoid leakage.

Best filter I’ve ever owned and it was cheaper than all the rest, I’ve used marineland and many others but they were all way to loud when I needed important sleep because my fishy and is less than 7 feet from my bed. I seen some reviews saying this filter is too loud (which it isn’t), if the filter is set up correctly and sitting just above water level the water makes little to no noise at all. I got up last night to check if it was working because I heard also lit let no noise at all and it was still on LOL. This was easily one of my best purchases on this site even though I’ve found so much good stuff on here. I’d give it a 10 star rating if I could.

This filter has exceeded my expectations. I was a bit nervous at first because of the price point and was completely realistic. I had quite a bit of debris in my turtle tank and the moment I plugged this filter in, it cleared up the water in minutes. Like... crystal clear. I was completely baffled. Definitely a great buy!

I purchased the 5-10 gallon filter to use in the water feature in my snake's enclosure when the pump I had previously been using wore out (it was a bit under powered, so I didn't want to replace with the same model). I've got a friend who has a larger version of Tetra Whisper pump/filter in their fish tank, and theirs has been reliable and quiet, so I figured I would go with the same brand and product line. The smaller model is pretty loud for something that claims to be whisper quiet. Since this is for a snake enclosure, I'm mostly concerned about vibration noise from the pump motor rather than water noise, since vibration will carry through the frame of the enclosure.

Since this is for a snake enclosure, I'm mostly concerned about vibration noise from the pump motor rather than water noise, since vibration will carry through the frame of the enclosure. The vibration is very audible when the enclosure is open. It's not enough to disturb me when the doors are shut, but my snake seemed pretty agitated and avoided that part of the enclosure for a few days (she is used to the water moving since there has been a pump and filter in there for a few years, so that wasn't the issue). Based on some posts in aquarium groups online, I put a pad in under the water feature and stuck a silicon trivet between the pump and the side of the water feature, which helped a little. It's still audible, but doesn't seem to bother her quite as much. I have anywhere from 3-5 gallons in the water feature at any given time, so maybe the claims of silence are based on having more water to muffle the vibrations? At this price point I really don't expect perfection and I doubt the other brands are much better, so I'll keep tweaking things until I'm happy with it. … more

Updated version of the same model I had for 5 years that doesn’t live up to the performance of the previous model. This one makes more noise. (Not Whisper quiet). Does not clean the water and leaves it very cloudy. Never had that problem previously. Water was always clear. Even the picture on the box is not the same as what they are selling now it’s a picture of the old model. This change should not have been made. Do not buy this product. No longer lives up to Tetra’s previous quality.

This filter is HUGE.. it's MUCH bigger than i expected. Also, on the ad it says for 10-20 gallon and the box says 10-30 gallon. I have a different brand of a filter with the same design for a 30 gallon that is half the size of this one so i did not expect it to be so big. The photo i added is in my 20 gallon.

Works perfect. Is totally quiet. Not sure why other people say it’s loud. Literally can only hear the faint trickle of water. I highly recommend.

It quit working after 5 months but I do like that it’s internal to prevent leaking and it’s fairly quiet. It’s cheap enough I’ll buy another.

I like the way this filters but attaching filter to tank is impossible. It supposed to suction cup to bottom but they don’t stay and it has an additional hook from which it keeps detaching. All in all not worth the money
