Fluval Aquasky LED Lighting
The Flex 123L includes an Aquasky 2.0 Bluetooth LED lighting system, giving you considerably more control than a conventional aquarium light.
Using a compatible mobile device, the lighting can be customised to create different colours and lighting conditions throughout the day.
A programmable 24-hour lighting cycle allows gradual sunrise, daytime, dusk and night settings to be created, helping produce a more natural-looking aquarium display.
The supplied LED features:
- 21W LED lighting
- 63 LEDs
- 42 white LEDs
- 21 RGB LEDs
- 1450 lumens
- Programmable lighting
- Bluetooth control
Fluval states that the supplied lighting is suitable for plants with low to medium light requirements, including plants such as Anubias, Java Fern and Cryptocoryne.
Powerful 3-Stage Filtration
One of the standout features of the Fluval Flex 123L is its filtration system.
Rather than having a large internal filter sitting prominently inside the aquarium, the Flex incorporates filtration into a concealed rear compartment.
Two independent media chambers provide mechanical, chemical and biological filtration to help maintain clean, healthy aquarium water.
Filter Media Included
The aquarium includes:
- 2 x Fluval Foam Filter Blocks
- 2 x Activated Carbon Inserts
- 2 x Fluval BIOMAX Inserts
The foam provides mechanical filtration by capturing larger debris, activated carbon provides chemical filtration, while BIOMAX provides a highly porous surface for beneficial bacteria involved in biological filtration.
Adjustable Water Flow
Twin multi-directional output nozzles allow the direction of returning water to be adjusted to suit your aquarium layout.
This provides greater control over circulation and can help distribute filtered water throughout the aquarium while allowing flow to be directed around plants, rocks, driftwood and other aquarium décor.
