Fluval Aquasky Review Planted Tank

Aquarium LED lights are becoming more and more popular with aquarists for various reasons. They are often much brighter than traditional fluorescent or incandescent lights, they last longer, and they can be tuned to create the perfect spectrum for your tank.

If you’re looking for a new aquarium LED light, the Fluval Aquasky should be at the top of your list. This light is packed with features that will make it perfect for any tank size and type. In this article, we will review the key features of the Fluval Aquasky, as well as some alternatives. We’ll also help you decide which size to choose and give you some ideal settings to get started.

Fluval Aquasky Overview

If you like highly responsive, uncomplicated, and economical products, we are sure you will take great interest in the Fluval Aquasky. We present nothing short of a versatile, unique, and super effective aquarium LED light with many great features to work with.

Fluval Aquasky Review Unboxing

Fluval offers five different aquarium lights. Fluval Plant 3.0 and the Fluval Aquasky are Fluval’s most improved LED light products. While none of its finest features have been lost, it has evolved.

This Fluval LED light has many lighting settings and preprogrammed presets, is highly cost and energy-efficient, and comes in various sizes to choose from. Anyone can ensure that their precious aquatic plants or coral get the amount of light they need to thrive.

Which Size to Choose?

There are two different sizes of this light to choose from

  • Fluval Aquasky 24 36 is a smaller model and is ideal for 24-36 inches wide tanks and weighs about 1.8 pounds.
  • Fluval Aquasky 48 60 is the largest model and is more suitable for bigger tanks of a 48-60inch width, and its weight falls at 3 pounds. 

I purchased the Fluval Aquasky 2.0 48-60, and that is why this article will be a Fluval Aquasky 48-60 review. Meaning we will be focusing on the larger version of it rather than the smaller one. However, the features remain as similar as they can get.

Best Settings for Fluval Aquasky LED

We’re confident that one of the essential aspects of Fluval Aquasky 2.0 is its sensitivity to the user’s experience. Indeed anyone can figure out the best way to set up their Fluval Aquasky LED lights, whether through previous experience, knowledge, or by learning as they go.

The FluvalSmart App comes with various presets that the Fluval Aquasky can translate into the light. If anyone doesn’t feel as confident in experimenting just yet, they can still use the light without a refrain.

The manual mode is ideal for people who are starting to understand how their planted tank thinks and feels and are willing to experiment a bit more to see just what their plants like best. Fluval Aquasky pro mode settings are excellent for people who want more control over their light. This can be especially useful for people whose planted tanks are not doing as well as they would like. 

Key Features

When deciding whether or not to buy a product, it is no secret that knowing the best and most important features of said product is the first step. Fluval Aquasky LED, like all Fluval lights, is jam-packed with fantastic features and is arguably the best product to come out of the company, thanks to numerous improvements in terms of technology and functionality. So without further ado, let us tell you all about this product.

Fluval Aquasky Review Light Coverage


Customizing the light settings with the Fluval Aquasky is possible due to the combination of this product’s white and RGB LEDs. This combination offers nothing short of thousands of different colors.

Fluval’s Aquasky comes preprogrammed with 11 different presets that beautifully mimic different moments of the day in the sky, giving your tank a high-quality natural environment replica. That’s ideal for anyone who doesn’t feel like experimenting but would rather cut to the chase with more natural feeling lighting. 

What is special about this particular light that you don’t see in other models is its full 24-hour cycle. This cycle can replicate different times of the day in terms of lighting. It can fully replicate a whole day to night lighting cycle, mimicking sunrise to day time to sunset to dawn, and so on forth.


Depending on the sort of fish you’re caring for, and the depth of your aquarium, enormous amounts of light may need to reach all the way to the bottom. Given this product’s IP67 water resistance, it can be placed at very close proximity to the surface of the tank water and endure continuous water splashing without taking damage.

Extra Features

The infrared SKYpad remote (included in the package) can control brightness, change colors and replicate sky-like effects with four memory save settings. Automatic light level adjustments are also possible due to an LED dual lamp timer.

The lights have great individual coverage, of 120° each. This will ensure that there is no weird spotlight-looking area in the tank and that the whole place is well lit.

The latter also to the security of the light being mounted closed to the water’s surface as we mentioned earlier, which has an additional benefit we haven’t mentioned yet. As obvious as it may be, it is very important that mounting the light closer to the water surface, makes for more energy being spent on illuminating the tank itself rather than the outside environment around the tank which wastes light, heat, and electricity.


Sometimes, a genuinely excellent product may appear too good to be true, or we may just want something different for many reasons. We have always made sure to keep in mind anyone who would like to know more about their aquarium LED lights options.

We included a variety of alternatives, each with their deliberate defining features to make sure any user’s specific needs are considered.
