• Hidden multi-stage filtration
• Version: Kit 123L, Black

Choosing size and colour

The kits are listed in black or white and in several volumes, so start with the space you have and the fish you plan to keep; larger volumes are more stable and easier to keep in balance. The 57L kit measures about 41 x 39 x 39 cm and uses 7500K white plus RGB LEDs that you adjust with a remote control. The 123L kit, the largest in the series, has app-controlled LED lighting with custom colours, dynamic effects and a programmable 24-hour timer, and its built-in filter has two independent multi-stage chambers.

Good to know

Cycle the aquarium for a few weeks before adding fish, and rinse the filter media in old tank water during maintenance.
