The Fluval Edge 6/12 gallon aquariums get an ‘A’ rating from us and most of its owners, and we highly recommend Fluval Edge aquariums as unique aquariums that are fun and easy to maintain. That being said, no aquarium or fish tank is without its flaws, and that includes the Fluval Edge. Even though the Fluval Edge is an excellent aquarium for beginners, seasoned fish keepers and everyone in between, the Fluval Edge still has limitations and every person who owns, buys, or plans on buying a Fluval Edge aquarium should understand the limitations of their aquarium set up in order to keep their aquarium and fish happy, healthy, and looking good.

Fluval Edge 6/12 gallon: THE GOOD

The Fluval Edge has a unique and elegant design and is the world’s first 3D water cube aquarium.

A floating base design gives the set a very small footprint for easy placement and lends the aquarium a clean, contemporary look.

Everything you need to set up your aquarium comes with it (except the fish).

It is a great aquarium for freshwater or saltwater.

The Fluval Edge comes complete with a powerful and efficient 3 stage filter which remains completely hidden, preserving the striking aquarium design.

The partially sealed top reduces evaporation for less maintenance and a large, hidden aperture allows oxygen exchange to keep fish healthy.

It can be filled to the very brim thanks to the glass top, providing high definition viewing from every angle.

A powerful, retractable halogen lighting system creates a visually stunning display.  Two 10 watt bulbs create a bright, directional light source for a beautiful ‘shimmer’ effect across your entire aquatic scene

A range of Edge cleaning accessories are available, making cleaning and maintenance child’s play!

It takes only seconds to assemble and the perforated, removable cover effectively dissipates lamp heat, avoids moisture and allows easy access to the filter’s lift out media trays.

Fluval Edge 6/12 gallon: THE DOWNSIDE

Though it has a stunning design, the only access point into the tank is the opening in the top glass.  This creates a couple minor problems.  It makes it more difficult to set up decorations and also requires the use of the specially designed Fluval Edge Accessories like the fish net or gravel cleaner.

The fact that it is only six gallons limits only smaller species living in the Fluval Edge.  Though there are still many many different types of fish and invertebrates that can live in the Fluval Edge, you will be limited to smaller species and quantities.

Species of fish like bettas or cory’s (corydoras) do not usually do well in the Fluval Edge as they need to gulp air from the surface of the water.  The Edge’s top glass prevents them from being able to do this if the water level is full.  With these fish and other fish that exhibit that behavior, the water level will need to be lowered a little.

The lighting system doesn’t illuminate the outer edges of the tank too well.  The middle of the tank is very bright while the outside is dimmer.  Though it is only a very minor problem with the tank design, it can be easily fixed with bigger light bulbs or adding more light bulbs.  An upgrade to the lighting  is usually the only upgrade made by most Fluval Edge owners.

FLUVAL EDGE AQUARIUM REVIEW SUMMARY:

There are plenty of different aquariums out there, all with good and bad qualities. There is no aquarium that is completely maintenance free, every aquarium will require partial water and filter changes.  However, the Fluval Edge is by far one of the easiest to maintain let alone one of the best looking aquariums.  The majority of the drawbacks to the Fluval Edge are very easy to work around like by using the specially designed Fluval Edge accessories, or by minor upgrades like the light bulbs.  They can be eliminated through good fish selection and reading the Fluval Edge  Manual carefully, as well as understanding basic principles of aquarium and fish care.  If you are considering purchasing a Fluval Edge Aquarium you will do well to understand both the positives and negatives of the Fluval Edge, and how to eliminate the negatives by setting up your fish tank appropriately.
