The best evah tortoiseshell filter!

The turtle owner is here. and if you know they are very noisy and very dirty. they absolutely contaminate their water. And all the other filters are so loud that I had to keep turning them off. This filter is exactly what I was hoping for! It is very efficient, cleans the water quickly and is very quiet! It also has a built-in aerator so we can remove the bubble wall. and the water is crystal clear. The filter is detachable and quick to disassemble for easy cleaning and makes water changes so…

Pros
  • Annual probationary period
Cons
  • The list will be long.

Submersible Filter 55g in Live Plants

I purchased this item because I was struggling with my cascade canister filter. My first impression is that it is very durable, but at the same time it is absolutely silent. It's unlike anything I've ever had. A test was done with just my new submersible filter and then with a cascade canister. The cascade actually degrades my water quality even though it had built in or new media. I've added many different filters to the cascade over the years, but no matter what I did, there was still a lot…

Pros
  • Free for Educational Use
Cons
  • Slightly Crumpled

BEST FILTER in the Filter Accessory

GOOD, this really is the best filter I have ever bought for my turtle. How ok this doesn't really guarantee your turtles water will be clear for a week BUT it does guarantee it won't be cloudy which I had trouble with when trying other filters prior to Fluval u3. I love that it literally keeps my turtles' water clean! Of course the water can turn yellow after a week if not changed so change the water friends 😂 but I love how it absorbs all the dirt and even the water flow is really good! My…

Pros
  • Great price
Cons
  • Upgradeable

My favorite filter so far! My fish love it!

This filter is everything my friend said! It works exactly for what I needed it for. I have this in my partially planted 5 gallon tank (some live, some fake) and my fish couldn't be happier! as soon as I put him in the aquarium, Freckles (my cock) was hooked on it. He rested on his summit for most of yesterday. And it doesn't hit all around the tank either, which bothers me with most filters. And the filter is also very flexible in terms of the media you can put in it. Since I have plants, I…

Pros
  • A sea of positive emotions
Cons
  • Very expensive

Quiet filter and great for turtles!

FINALLY a filter that works for turtles. This filter can be side mounted, which is great news for turtle owners who only fill the tank halfway to make room for a turtle swim platform. Most filters are designed to pull water to the very top of a full tank. This filter can be installed both vertically and horizontally to accommodate lower water levels. It's also the quietest filter I've ever had. The entire filtration process takes place below the water level, so there is no sound of running…

Pros
  • Stylish and modern design
Cons
  • Doubtful purchase for the elderly

IN LOVE WITH THIS FILTER

Update: Not a big fan after a month of using this filter. Button on top to change flow, hard to turn and painful to turn! In addition, the handle can be easily removed. The middle part for Biomax etc. Hardly anything fits in there, it's so small - I have to cut most of the available bags or make them myself. Knowing all this, I would probably get a different filter. The only good thing is that it's quiet and my loaches and pleco love to hide under it. Old review: It's submersible so if you say…

Pros
  • Hands-Free Operation
Cons
  • Operating Speed

Confused by bad reviews

I've been using this filter in my 45 gallon aquarium for a few months. I was confused by two things other reviewers comment. 1) This filter is NOT noisy. I can not hear. General. Compared to other filters, the noise factor is negligible. So unless you intentionally put your ear to this thing, you won't hear anything. 2) On shrimp / roast. I have red cherry shrimp that breed like rabbits and the fry are INTENTIONALLY hanging in the slots between the outer and inner foam. They don't "suck in" and

Pros
  • Great for a small home
Cons
  • Doubtful

Great filter. But the U3 might be a bit small for my 40 gallons.

I have a planted 40 gallon Lang (48 x 13 x 17) and needed to replace an old Fluval 202 canister filter. Really didn't want a new canister filter and the bio wheel didn't work for me because of the plants. There are HOB filters that would work, but in my experience they are just as clumsy and difficult to clean as a full canister. So the U3 seemed like the perfect compromise; No filling, no hoses, just dip and go! This filter is very easy to clean and maintain. I like the central "spray bar"…

Pros
  • Excellent Overall Performance
Cons
  • Useless Features
