Pros
- RGB + 6500K white LEDs make fish colour genuinely pop
- FluvalSmart app adds a 24-hour cycle, weather effects (cloud, storm) and a timer
- IP67-rated, safe to sit right above the water line
- Wide 120-degree spread lights the whole tank evenly
Cons
- Tuned for looks over PAR — fine for easy plants, not a high-tech grow light
- Bluetooth-only app needs you near the tank and can drop out
- Weather effects are fun but gimmicky for day-to-day use
Built to show fish off
Where a plant light chases PAR, the Fluval Aquasky 2.0 chases colour and coverage — and that is exactly right for a community tank. Its RGB plus 6500K white LEDs make tetras, guppies and gouramis look their best, and the wide 120-degree spread lights the whole tank evenly. The FluvalSmart app layers on a full 24-hour cycle, a timer and playful weather effects, all from your phone.
Good for easy plants, honest about the rest
The Aquasky will keep low-light plants — anubias, java fern, crypts, mosses — happy, so a lightly-planted community tank is well within its range. What it is not is a high-tech grow light: it is tuned for looks over output, so a demanding carpet or red-plant scape needs a dedicated fixture. And the usual rule still applies — run it on a 6–8 hour photoperiod with the app timer, because more light without matching CO2 and ferts just grows algae, whatever the light was designed for.
How it compares
Planting heavily? The Fluval Plant 3.0 is the same app ecosystem with a plant-focused spectrum, and the Chihiros WRGB II Pro 60 is the high-tech step up. On a budget, the NICREW ClassicLED Plus covers easy plants for far less. See the whole range on our aquarium lighting hub and size a tank on the aquariums page.
The pick when the tank is about the fish, not a carpet. Superb colour, a proper day cycle and easy-plant capability in one tidy app-controlled bar — just don't expect high-tech growth from it.

Fluval Aquasky 2.0 — frequently asked questions
Can the Aquasky 2.0 grow plants?
It grows easy, low-light plants — anubias, java fern, crypts — comfortably. It is tuned for colour and coverage rather than raw PAR, so for a demanding planted or high-tech tank, a dedicated plant fixture like the Fluval Plant 3.0 is the better tool.
Does more brightness mean more algae here too?
Yes. Even a community-tuned light will feed algae if you run it too long or too bright with nutrients in the water. Keep a 6–8 hour photoperiod on the app timer and do your water changes — that is your best algae defence.
What is the point of the weather effects?
They simulate clouds, lightning and storms for visual effect. They look great occasionally but do nothing for plant growth — treat them as a fun extra, and rely on the plain 24-hour cycle and timer for everyday running.

Our score
8.3/ 10
The pick when the tank is about the fish, not a carpet. Superb colour, a proper day cycle and easy-plant capability in one tidy app-controlled bar — just don't expect high-tech growth from it.
Who this one is for
A 24–36 in community tank with fish and easy plants, where you want vivid colour, a natural day cycle and app control more than maximum plant growth.
