This article doesn't list every Fluval Fish tank available.

Instead we have compiled a list of just 5 Fluval aquariums that we really love and think would make the perfect tank for your home.

Fluval fish tanks are crafted in Germany to an extremely high quality standard. There are seven ranges in the Fluval collection and each of them has its own unique design features. The collections are; the Reef m, the Fresh f, Roma, Chi, Spec, Accent and Edge. Fluval Aquariums blend both style and functionality perfectly and look great in all households.

All the Fluval fish tanks in the Fluval ranges come complete with a Fluval heater, Fluval filter, lighting, a marina thermometer and complete aquarium guide. Matching cabinets are available for most of the collections in oak and black. Many also come with décor strips in oak or white. Fluval fish tanks as standard usually come in black.

In the Fluval collection there are two one off designs only available in one size. These are the Chi and the Accent. The Chi is based around the laws of Feng Shui creating a perfect balance of sight and sound. At only 19 litres it is a good option for those limited with space. The Accent is a 95 litre tank that’s main selling point is that it easy to install, taking under 60 minutes and easy to maintain, just 10 minutes a month.

There are also two small collections with only two size of tank available in each. The Spec pairing are of a contemporary design meant for smaller living spaces and are available in 10 litres and 19 litres. The Edge collection are cube shaped tanks which conceal all equipment and are stylish. They are available in 23 and 46 litre capacities.

Fluval Chi

Inspired by the art of Feng Shui the Fluval Chi is the perfect balance of sight and sound. Feng Shui stimulates the essence of chi and is inspired by the values of life, health, prosperity and everything that is positive. The sound and motion of the bubbling water and the ambient illumination of the Fluval Chi represent this perfectly.

There are 17 powerful LED lights plus a permanent up light providing a gentle glow in this tank. It has a powerful filtration unit which promotes sparkling, healthy water. The cube of this tank is rotatable enabling easy cleaning and replacement of filter pads. It includes filter media.

Fluval Chi Review

The Fluval Chi is an easy to set up tank with the capacity for 6 tropical or 3 cold water fish based on adult fish of 3cm. It is not suitable for marine fish. It's very reasonably priced but it needs to be noted that to make it a tropical tank a heater will need to be purchased. You can pick these up for around £20, we would recommend taking a look at this page to find out more about which heaters are best for smaller fish tanks.

The Fluval Chi is a dainty tank with a capacity of just 19 litres. Measuring only 25.4cm (L) x 25.4cm (W) x 36.5cm (D) which makes it ideal for beginners.

Although these tanks are small, thanks to their unique stylish design they attract the eye and immediately change the mood of any room you place them in. The fluval tanks have been selling great online thanks to the demand in small stylish tanks for busy people who may not have the room required for a more traditional shaped aquarium.

The Fluval 90 has a capacity for 30 tropical fish or 15 cold water fish based on 3cm adult fish. Marine fish capacity would be 3 inch per square foot of tank. The suggestion would be that this tank would be a little on the small side for marine fish keeping, however that being said it is possible.

The fluval roma 125 could be considered the starter tank due to its size and price, however that is not to say that this cabinet and tank combination should be overlooked.

From a quality and visual point of view the Fluval Roma range are a set of rectangular tanks with clean and simple design. They will bring a sophisticated look to any modern room. Made in Germany and crafted to extremely high standards not only will they look good, they will last an age. Which brings me to another point, you do not have to buy a brand new roma tank, websites such as eBay or your local fish store classified section can be a great place to find a bargain. Since the tanks are built so well, and generally fish tanks dont move around much you can find them in almost perfect condition, especially if they are from a smoke free home.

Fluval Roma 240 Review

The Fluval Roma 240 is not the cheapest of the fluval fish tanks but it is a good quality, good size option. The tanks water capacity will hold up to 80 tropical fish or 40 cold water fish based on 3cm of adult fish. Marine fish capacity would be 3 inch of fish per square foot of tank. You may run into some difficulty trying to get your hands on this tank online so we would recommend keeping an eye out on websites like eBay or Gumtree for good deals.

The instruction manual can be found online for free here, we also recommend people read any documentation before buying as it can contain important information. For example "Note: this aquarium must be used with the correct Fluval Roma cabinet due to the through-tank filtration system."
