Custom Aquariums – Built to Your Vision

At GTA Reef, we specialize in crafting fully customized aquariums designed to match your exact needs, style, and space. Whether you're creating a modern living-room showpiece, an extensive coral grow-out system, a commercial installation, or a unique architectural feature, we bring your vision to life with precision engineering and premium craftsmanship.

Our custom aquariums are constructed using ultra-clear, low-iron glass, professional-grade silicone, and reinforced cabinetry designed to withstand long-term water loads, humidity, and advanced equipment. Every build is tailored to your specifications—including dimensions, overflow placement, sump layout, cabinetry finish, lighting integration, and equipment compatibility.

If none of the standard tank sizes meet your needs, we will design and build a custom aquarium tailored precisely to your vision.

We partner with trusted North American builders to deliver tanks that exceed industry standards in durability, clarity, and design. From minimalist rimless cubes to oversized peninsula systems and dedicated frag tanks, we ensure your custom setup is both beautiful and engineered for long-term success.
