What is the minimum amount of water (20 Gallon long tank) in inches needed for this filter to work properly? it is for a turtle

Answer by Chewy • Jan 12, 2018
To use this product you will need approximately 6-7 inches of water.

Would you recommend a small 5-10 or a 10-20 for a 10 gallon tank?

Answer by Chewy • Aug 07, 2019
To determine which filter is best for a 10 gallon tank, it's best to consider what type of fish is in the aquarium. For example, if you may have a betta fish then the smaller filter may be more appropriate however, if you may have other species or multiple fish in the tank, then the larger 10-20 may be better.

Can i use 2 filters for a 55 gal tank?

Answer by Chewy • Jan 23, 2018
You can certainly use 2 filters. Just ensure it's paired close enough to 55 gallons.

stupid question. does it also put some oxygen in the water.

Answer by Chewy • Jul 21, 2019
Filters move water from the top to the bottom of the tank, thus distributing oxygen throughout the aquarium.

Whisper is no joke!!

I suffer from misophonia so it’s important for me to have quiet equipment for my aquariums. My marine life also requires a steady but smooth flow so it’s important

I suffer from misophonia so it’s important for me to have quiet equipment for my aquariums. My marine life also requires a steady but smooth flow so it’s important I pick the best setup. Needless to say, I have one in each tank because they’re so great! Easy to setup, functional, efficient, and QUIET!

Efficient and economical

This is the only filter that puts up to the abuse from a large snapping turtle. I actually have 2 of these in his enclosure.

Quiet pump.

I purchased this Tetra Whisper filter to replace the serviceable but noisy 5-year-old Penn-Plax filter on my 10-gallon goldfish tank. The design on this Whisper unit allows it to operate with far less vibration, so it can live up to its name -- a must, as my aquarium sits atop the dresser in my bedroom. It's a bit bulky for a 10-gallon aquarium, but I'm planning to upgrade to a 20-gallon tank in the near future, so I wanted a filter that would grow with me. I just installed this filter last night, so I can't speak to its durability, but thus far, it appears to be a quality product. My only quibble with it is that the plastic mounting bracket seems a little flimsy -- not an issue at the moment, as the unit rests on the bottom of the tank, but potentially a problem in a larger aquarium.

Not worth it

I purchased this a year ago, the impeller stop working. It's still under 2 year warranty, but Tetra representative blame it on wear and tear. She refused to replace

I purchased this a year ago, the impeller stop working. It's still under 2 year warranty, but Tetra representative blame it on wear and tear. She refused to replace the part and keep telling me to buy the impeller, which only available online with shipping and fees. My advise is to invest in something with better quality and excellent customer service.

Cheaper is Better!

I use these for my turtle tanks and they work better than the expensive filters I have tried. Most of them have enough room to also add extra media, which does not

I use these for my turtle tanks and they work better than the expensive filters I have tried. Most of them have enough room to also add extra media, which does not affect the flow. Easy to clean

Good luck

Worked like a breeze, for 2 months then stopped. I was very disappointed but getting a refund was hassle free and now I have to get another one.

It was very quiet

Although it was nice and quiet, the rear attachment doesn't hold...it just keeps sliding down unless you put something at the base hole that holds it,

Tetra Aquarium Filter 10-30 gallon

I am going to need to purchase another filter for my aquatic turtle 20- gallon tank. I love the hanger option as I had trouble w/ suction cups holding the other

I am going to need to purchase another filter for my aquatic turtle 20- gallon tank. I love the hanger option as I had trouble w/ suction cups holding the other Tetra filters I previously used. But the one filter I purchased first is not enough to keep the water clean enough for more than a few days. Perhaps it's not best for turtles, even though the use for turtle tanks was listed in the description.
