Oase Highline 125 The Oase HighLine 125 Premium Package includes Premium LED Lighting with EAC Controller and a BioMaster Thermo 250 filter.

The Oase Highline is a stunning new aquarium which combines a beautiful high-quality glass front with a stylish stainless steel back panel. This aquarium is perfect for both fresh and saltwater fish and comes complete with everything needed to set up your own home aquarium.


  • 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.
