Fantastic Features Of Fluval Flex 57L
I’ll focus on the Fluval Flex 57L aquarium features that will somewhat benefit the aquarium keepers. I try to keep my review fact-based because you’ll invest your money relying on my review. So I believe the study should be unbiased and honest.
Fluval Flex 57L fish tank comes up with 2450 lux LEDs capable of creating a shimmering effect and an innumerable number of color combinations. Simultaneously, the 7500K LED-lamp is produces a complete spectrum that can promote live plant growth.
An essential consideration of a lighting unit is how comfortably you can control it. This product features a super easy FLEXPad remote control. You can choose from an enormous number of color blending and special effects as per your likings.

Three-Stage Filtration System:
When you are an aquarist, you’ll find the main challenge is to maintain the aquarium environment healthy, explicitly ensuring the water quality. Therefore, an effective filtration system is crucial.
Fishkeepers, especially beginners, often struggle to identify a suitable filter for the tank. Fluval Flex aquarium will relieve you from this hassle.
The Fluval Flex 57L aquarium includes a three-stage filtration system. Three water purification stages are mechanical, chemical, and biological filtration, with foam, carbon, and BioMax as filter media.
A multidirectional dual output feature will give you the option to customize the water flow. Flow customization option is useful, especially if you keep Betta fish or live plants like Frogbit or Duckweed in your aquarium. These inhabitants are not comfortable with high water flow.
I want to add one more vital point. Filtration units are essential but not visually pleasing. In the Fluval Flex 57L Aquarium, the entire filtration system is hidden in a rear compartment. A stylish honeycomb mask conceals the filtration unit without hampering its primary function.
Sleek And Elegant Outlook:
The curved front of the aquarium can create an illumination of a broader view of an underwater world. Fetching lighting with appropriate décors can take the beauty of this aquarium to a whole new level.

How To Choose A Suitable Heater For Fluval Flex 57L
Fluval Flex Comes with so many useful features, but it does not come with a heater. The heater is an essential item for an aquarium, and you cannot do without it. So you have to pick a suitable heater for the aquarium.
In a simple rule of thumb, while selecting a heater, the bare minimum watt you need is 2.5 times the tank volume. That means for a 15-gallon tank; a 37.5-watt heater is a minimum requirement.
But remember, the ambient temperature plays a vital role here. If you live in a too cold place, where the required temperature rise of water is 10 degrees Fahrenheit, for say, you will need a 150-watt heater.
Suitable Fish For Fluval Flex 57L
You can make it a Betta tank, but Bettas are not community fish. If you wish to make a community tank, pick from Danio, Molly, Platy, Guppy, Tetra, or Swordtail.
Does the Fluval Flex 57L come with any decor?
Fluval Flex Comes with so many useful features, including complete lighting and filtration system. But the rest you have to buy additionally. You definitely have to buy a suitable aquarium heater, decors, and other accessories like a water conditioner.
Can this model of Fluval Flex be used for saltwater?
No, this model of the aquarium offers features only for freshwater use. The glass tank is useable for both in the freshwater and marine aquarium. But the other accessories, especially the filtration system, are not designed for saltwater use.
Can I use it as a planted aquarium? What type of plants would be better for it?
Lighting is the Fluval Flex 57L fish tank’s focused feature and has good lighting options to grow live plants. This product’s lighting unit allows you to adjust the light for bright to low settings. Any freshwater plant (high, medium, or low light) is suitable for growing in this tank.
Is the filter an Undergravel filter?
The filter remains hidden in a rear compartment, and a stylish honeycomb wrap conceals the entire filtration unit. Still, it is not an Undergravel filter. The circulating pump sucks water through two intake vents, one at the upper left and another at the lower left.
How many fish are in Fluval Flex 57L?
There is a thumb rule for rough estimation that is one inch per gallon. That means in a 15-gallon tank, you can keep fish with a total of 15 inches in length (for example, three fish of five inches long).
It is only a gross estimation; however, in a 15-gallon tank with an effective filtration system, a combination of 6 to 8 small and medium fish is quite perfect for keeping.
