Built Like A Tank

We don't accept just "acceptable standards"

Anodized Aluminum Frame

We make a patented black anodized aluminum frame. The frame is stronger than plastic or euro bracing.

Our frame will never rust, corrode, or become brittle from salt and light exposure. It is the strongest most advanced frame on the market.

Precision Glass

We use thicker stronger glass for our aquariums. We also bevel and polish every edge of each pane of glass, even the edges hidden by the frame.

We use glass over acrylic for its scratch resistance, strength, and resistance to chemicals and yellowing.

High Strength Silicone

Our aquarium-grade black silicone is five times stronger than standard clear silicone.

The strength of an aquarium is dependant on the strength of the silicone bonding.

Our Aquarium Stands

Majestic® Stands & Canopies

Not all custom aquarium stands and canopies are created equal! Our Majestic Enclosures® have many advantages over other brands. With a solid 3/4" plywood top and back as well as a solid hardwood framework, no shortcuts are taken in our designs. You will not find any particle boards, which tend to swell and crack over time, used in our stands or canopies. While we have many standard styles and stain/paint colors to choose from, we can also custom match your decor. All of our freshwater and saltwater aquariums are built in-house by our full-time professional craftsman. Our stands and canopies are not just practical but are also genuine heirloom quality hand-made furniture pieces. With materials made in the USA, you will not find a better value of quality craftsmanship and price anywhere else for your custom fish aquariums, freshwater fish tanks, and saltwater aquariums.
