Fluval Edge 6 Gallon Version

Now, before we get started with the big guy, just in case you deemed it too big for your needs, there’s always a 6-gallon version. Obviously, it won’t hold as much as the 12 gallons, but it does the work the same and is built with the same care and thoughtfulness.

Most of the things are relatively the same besides the dimensions, which go by 10.24 x 16.93 x 17.32 inches. Other than that, the weight (8.62kg) and the overall size of things being smaller to suit the tank’s size, you’ll have the same experience either way.

The shape is rectangular, meaning it fits in most spaces comfortably, taking its small size into account. As said earlier, this is for people who don’t need a big tank or have much fish to hold, meaning this wasn’t meant for everyone. However, if the size fits your needs, rest assured you’ll have a fully functional tank with a great aesthetic built with care and quality materials.

What’s Included in the Box?

We said earlier that Fluval puts much thought into what they deliver, and the unboxing is surely an experience. You can tell the quality level and the uniqueness of the design language right away.

Like most others from the same manufacturer, this product is rotated around aesthetics. However, this doesn’t leave other aspects behind. There are some real quality products included in the box, and they each are custom-made to fit your aquarium perfectly, not only in size and overall vibe but also matching in quality and ease of use. The list of products that come along is as follows:

  • The tank
  • The filter (Multi-stage filtration)
  • The pump
  • 6000K LED light

The classic edition of what a tank should absolutely come within a Fluval-esque style is the best thing you can do for your fish.

Key Features of Fluval Edge

This product is made for experienced fish-keepers and beginners alike, and our review will hold on to that standard. Below you have all you need to know about this tank that will help you make this purchase no matter your knowledge on the subject.

Design of The Tank

With a sleek and contemporary design, the Fluval Edge fish tank has glass on six sides, so you can appreciate your fish from all angles and showcase them to all guests, no matter where they’re coming from. As we’re well aware, Fluval is known for its excellent-looking tanks that have unique aesthetics and clean looks.

What we like about Fluval Edge is that you can have the option to choose between 2 different designs. You can go with the 6 gallon version that has a cuboid design, or if you like cube aquariums (like me), you can choose the 12 gallon version.

The Fluval Edge aquarium rests on a color-matching base with the other components of the tank. Equipment and unattractive wires are hidden as the base, and a rear panel connects the hood. There are quite a few color choices. However, the black base is a classic. The easiest to match with your home décor and the best to emphasize the colors on the inside of the tank, showcasing your beautiful fish, decor, and other sea creatures on it.

Filtration System

The Fluval Edge 6-gallon aquarium includes a motorized filter that hangs on the tank’s rear. The power filter is hidden behind the back panel that joins the base and hood. The filter is extremely strong and quite silent. It filters the water three times in a mechanical, chemical, and biological stage to ensure a clean and healthy habitat for your fish and shrimp.

Furthermore, the filter facilitates correct gas exchange and gives an adequate oxygen level for the fish. The filter is so silent that you may install the tank anywhere in the house, even in your bedroom, if you deem it right.

Lighting System

A vital white 7600 K LED light, and a deep blue night-time LED light are incorporated into the lid for daytime and nighttime illumination. Using a three-position switch, the lighting system may be switched between brilliant daytime, deep blue nighttime, and off to create a good system for your fish that boosts their natural cycle.

Having a tank with plants will be easy exactly because of the brilliant white daylight setting. There’s a gentle water flow generated by a filtration system that enhances the interior’s attractiveness. All together with the lights, it makes for an incredible visual experience that’s sure to give you a unique mix of comforting feelings.

Set up and Maintenance

Assembling the Fluval Edge takes only a few minutes. By the time you’ve opened the instructions, with a little multitasking, you’ll be able to set it up on a whim with no problem. Everything snaps together, and the last thing to do is slide the tank in the stand.

As for maintenance, there’s not much to do, or at least nothing more than any tank, and less than most of them. Make sure to follow general aquarium maintenance for your aquatic life.

The cover can be removed for simple cleaning, has quick access to the filter, and also prevents the aquarium from overheating.

You might find the pump kind of loud, but if you put marine-safe silicone lubricant on the pump, the pump’s volume will decrease with time. Aside from its visual appeal and functionality as a fish tank, it’s an excellent investment for it won’t take funds over the years for it’s age-proof and unless you physically slam it to the ground, it won’t get damaged easily.

Fluval EDGE Algae Magnet

Normally, algae tend to accumulate in fish tanks, especially on glass surfaces at the tank’s bottom. Now besides the functional problems, that’s also aesthetically unpleasant, so it makes sense to find a way to fix that that’s not time-consuming at all.
