It seems the LED it comes with is intended for low light plants only, which is what I would recommend planting.

If you are adventurous and want to add CO2 and fertilizers, then take a look at replacing the stock light with a Finnex Fugeray or something similar.

When I first saw this tank on sale, I knew I had to have it. The Fluval line of aquariums suit the planted tank hobbyist’s needs well. I immediately saw the potential in aquascaping this tank.

I have always preferred a long aquarium vs a cubed aquarium. When aquascaping long aquariums, it’s easier to get  a nice golden ratio which is appealing to the eye. I posted some of my tank pictures below of when I first planted it.

Fluval Spec V Features:

  • Includes foam block, activated carbon and BioMax bio rings.
  • 37 LED Lighting System suitable for live plants.
  • Etched-glass tank with aluminum trim.


  • Etched-glass conceals separate filtration chamber nicely.
  • Longer design allows for more fish, more plants, more everything in comparison to it’s little brother the original Fluval Spec.
  • Filter pump and filtration system are conveniently located in a separate chamber, staying unobtrusive to your aquascape.


  • Lighting may not be strong but suitable enough for beginners that want to keep low light, low maintenance plants.
  • Due to its light design, the light doesn’t stay exactly parallel to the aquarium top which may bother the perfectionist.
  • Filter pump flow can be too strong to keep betta fish.
  • Lid a little on the flimsy side.
