Product Information

The Fluval Flex 123 Litre aquarium makes an exciting addition to Fluval's bold curved aquarium series. It comes fully equipped with full spectrum Marine 3.0 LED, which operates via the FluvalSmart App on your mobile device. This has a 25000K color temperature, which is ideal lighting growing vibrant corals. There are 3 pre-set lighting conditions which you can choose to take advantage of - sunny reef; deep sea glo; color boost. The lighting has a 24-hour programmable light timer, so you can mimic the natural cycle of the sun and moon, and there is also optional space to add a second Marine 3.0 LED if you wanted (sold separately).

In addition, this all-new Flex includes a built-in 3 stage filtration system, with 2 independent multi-stage chambers for maximum cleaning efficiency, and 2 oversized mechanical (foam); chemical (carbon); and biological (Biomax) media - all included. The twin output nozzles can be completely adjusted to create the right flow for you, and there is a hidden rear filter compartment, which provides separate media access and also offers seamless integration of Fluval PS1 Protein Skimmer (sold separately) and M-150W Heater (sold separately).

It comes complete with easy-feed door opening, and a special honeycomb print camouflages the water line. The black curved stand compliments it perfectly, and allows for easy storage of essential items.

  • Twin output nozzles that can be adjusted to create customized water flow
