An outstanding aquarium with many useful features, the Oase Highline 300 is the perfect centrepiece for any room.

What is the Oase Highline 300?

The Oase Highline 300 is an outstanding freshwater aquarium and cabinet combination designed to hold cold water and tropical aquariums. In keeping with Oase's incredible reputation in the aquatic community, this aquarium has been built to the highest standard. The practical tank design features a filter intake and dry shaft, to connect an external filter and other hardware easily, a sleek aluminium cover and integrated LED lighting.

The cabinet continues the outstanding design with a modern finish, that will look spectacular in any home, and handle-free cabinet doors. Each kit comes in an easy-to-assemble flatpack set with everything you need to build a truly incredible aquarium.

What are the benefits of the Oase Highline 300?

The Oase Highline 300 boasts a fantastic range of features that will enhance the underwater world you're creating in your aquarium, including:

  • OptiWhite glass - Highline OptiWhite glass is used throughout the tank. This special glass is designed to have no distracting green tone, providing a clear view of your aquarium inhabitants. The glass also has the added benefit of creating bold, clear lines that enhance the overall linear furniture design.
  • Hidden connection - Built into the tank are both a dry shaft and a bottom drain that enable a hidden connection to any aquarium hardware set up in the cabinet beneath the aquarium, such as your own chosen external filter. This lets you incorporate lots of key aquarium hardware without compromising on the design of your aquascape.
  • Modern and contemporary lighting - The aluminium cover has space for LED lighting (sold separately) that has been carefully calibrated to create an optimally coordinated light spectrum which will enhance the colours of your aquarium inhabitants and plants, helping them look their best.
  • Aluminium strip - Around the base and top of the Highline OptiWhite 300 tank, there's an aluminium-effect strip that conceals the substrate at the base and the lighting at the top to draw focus to the fish, plants and decor within the aquarium.
  • Aluminium cover- The canopy of the tank is made from Aluminium for a sleek and understated finish. Within the canopy is a feeding flap that can be connected to an automatic feeder.
  • Adjustable feet - The base cabinet has six adjustable feet that can be set to suit any flooring perfectly, creating a perfectly level tank.
  • Storage space - The cabinet has been designed to complement the tank perfectly with practical drawers, outstanding quality push-to-open doors, a pull-out shelf and a large area for aquarium hardware as well as any messy external hosing. The space can hold up to two drawers.
  • Push-to-open function - To ensure the Highline aquarium perfectly matches its surroundings, the doors are inconspicuous and open with a single push. This also reduces the disruption to the tank caused by doors swinging open and banding against the unit.

What colours does the Highline 300 come in?

You can choose between a variety of cabinet colours including white, natural oak, black and anthracite for your aquarium. The tank is designed to complement each of these colours, creating a unit that is unique to you and the centrepiece of any room.
