Hagen Fluval 104404

Pros: Very quiet, lots of filter media, keeps water clean and clear, powerful, well-designed, price
Cons: None

We have had aquariums for years. Most recently, we acquired a painted turtle. Boy, are turtles messy critters. Tommy, as he’s called, has also grown quite a bit. When he was a baby, I was cleaning his 20-gallon tank every week or two, despite the ...

Pros: Very Quiet, Sparkling clean water and easy to find filter media for 3 internal baskets.
Cons: Flow rate slows down considerably once media is installed.

I have had aquariums for at least 20 years now. Tried every brand of filter made. My last filter was the Fluval 204. This filter when bought was easily put together, although the instructions are a bit lacking. I figured out how to put the filter...

Pros: Economical. Efficient. Sturdy.
Cons: I wouldn't complain if they were even cheaper.

When we were all enjoying the x03 line of the Fluval canisters, Hagen was busily drawing up a new generation of canister. When the x04 filters came out about two years ago, you could almost hear applause when you opened up the box.
Some of the joys...

Pros: Great Filter, Professionally Built, Reliable
Cons: Instructions Are Lacking

I moved into a new apartment, and had a perfect spot for a "dream fish tank" I've seen. Before moving here, I had a 35 gallon freshwater tank for about a year or so, but wanted to start a saltwater tank, so I wound up buying a 92 gallon Corner...

Pros: Second most effective filter on the market, best deal. Does everything
Cons: none

When I sell tank set ups I recommend people purchase Fluvals over Aqua clear or Whisper power filters. There are a few reasons for this. There is only one filter that is better than this one, but it costs twice as much and is only a little bit better....

Pros: Good quality, quiet, easy maintenance
Cons: Terrible instructions, assembly a little difficult

My wife and I had been wanting to get a saltwater tank sometime in the future, but we weren't prepared for the startup cost involved. When we returned from our honeymoon, lo and behold, a 30 gallon tank had magically appeared in our apartment. My new...

Pros: quiet, powerful, super easy to maintain
Cons: expensive

What a piece of cake to maintain. I’ve had a Fluval 104 filter for a couple of months now and just changed the media for the first time a few weeks ago. It was fantastic.

I’m using this filter on a turtle/fish tank. My previous filter...

Pros: Highly Efficient and Versatile
Cons: None.

Working in the aquarium buisness for over 10 years has exposed me to an entire world of questions and trouble shooting problems in regards to water quality. Most oftenly the issues lie within filtration. This filter has put an end to the common ...

Pros: Easy installation, great flow, very quiet. Compartments are great.
Cons: Plastic clamp handles scare me - use caution!

This filter simply amazes me. It's very quiet, produces good flow and crystal clear water. I am a little worried about the plastic clamps, but they seem pretty strong, and if one is careful when putting them on, they shouldn't be a problem. The ...

Pros: Quiet, powerful and effective
Cons: None as yet!

We bought this Fluval 1 filter 3 years ago and so far it has operated perfectly. Noiseless, efficient and powerful.

Our goldfish enjoy the caresses of it's cuddly eddies and currents. Both enjoy chasing their food around the surface as the...

Pros: Powerful,many compartments for filtering options, and price.
Cons: I would have to say instructions, although I had no problems what so ever.

Hello, I bought this filter 4 1/2 months ago let me tell you it is fantastic! I have this filter filtering a 55 gal community fish tank with about 16 fish and the water is crystal clear! The assembly was not to bad, I read a few reviews saying that the...

Pros: Crystal clear water and easy maintenance!
Cons: Poorly written instructions, takes some time to set up.

I purchased a Fluval 304 for one of my 55-gallon African Cichlid tanks, and I couldn't be much happier with it. The tank was previously filtered with a powerhead-driven undergravel filter and a Whisper external power filter. Although the tank had...

Pros: None
Cons: Leaks

My new 404 is a worthless nightmare

It's a poor design. The motor housing (with large o-ring at the top) will not seal properly. Following the directions very carefully, it still leaks like a sieve. It takes dozens of tries to get the motor...

Pros: Easy to set up
Cons: High failure rate

On the surface the Hagen canister looks like a great filter. When first introduced it was recalled within a few days. It was released again and problems continued. There are a lot of problems that surface after several months usage. How do I know? let me...

Pros: easy to clean/use
Cons: I don't like the hoses

I have had the Fluval 404 for over a year now and have nothing but good things to say about it. I use it on a 75gal cichlid tank with 12 africans (peacocks/elc blues.The versatility of this filter is endless from biomaterials to carbons the choice...
