Aquariums Brisbane  “Classic Aquarium” 

(Length x Width x Height) 3ft x 18 x 18 - 915mm x 450mm x 450mm

Designed and handcrafted in our Brisbane workshop, the Classic range brings together years of practical fishkeeping experience with proven aquarium construction methods. Whether you’re setting up your first aquarium or you’ve been in the hobby for decades, the Classic range provides a strong, dependable foundation for your next setup.

Every aquarium is constructed using brand new glass and high-quality, purpose-specific silicone. Glass thickness is selected in accordance with our established safety factor standards, with every aquarium designed to meet or exceed our minimum safety factor for long-term strength, reliability and peace of mind.

Full top cross-bracing is incorporated for structural support, with bridges positioned at a minimum of every 600mm where required. Two-part sliding glass lids are included as standard and thoughtfully notched at the rear corners, allowing practical access for filtration pipework, hoses, electrical cords and equipment.

There are no unnecessary gimmicks and no shortcuts hidden behind the glass — just a well-thought-out aquarium built by people who understand how aquariums are actually used.

Built right here in Brisbane, Australia.

With a large selection of popular Classic Aquarium sizes readily available from our workshop, your next aquarium is already waiting for you.
