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.

Lifetime® Stands & Canopies
Our Lifetime® aluminum-framed stands and canopies are some of the most durable of any custom aquarium stand and canopy system available on the market today! They make a perfect fit for anyone looking for a reliable aquarium stand and canopy for their freshwater or saltwater aquariums. The frames are made from anodized aluminum that will never rust, chip, or corrode. They are very lightweight, yet they are engineered in a way that allows them to withstand extreme loads from even large tanks! These stands and canopies take only minutes to break down, resulting in easy transport, storage, and installation.
Our Aquarium System

Seamless Sump® Aquarium Sump
Developed by aquarium service experts with decades of experience at the aquarium service division of our sister company Serenity USA, the Seamless Sump system is a complete filtration solution for both fresh and saltwater custom fish tanks, large and small. Our one-piece, "Seamless Sump®" system combines the best features of each type of filtration system into one elegant, easy to service, long-lasting solution.

H2Overflow® Aquarium Overflow
Also developed by aquarium service experts at our sister company Serenity USA, the patented H2Overflow® is the perfect solution for safely and efficiently returning your aquarium water to your sump filter. Whether you have our recommended Seamless Sump® or another brand of sump, the H2Overflow® is extremely quiet, has a large skimming surface area to provide aeration, maintains a consistent water height, displaces a very little amount of water, and has a very small footprint to stay out of sight and out of the way of your lighting.

Stealthbox® Overflow Box
The H2Overflow Stealthbox® is the most versatile, silent, and reliable external aquarium overflow system available anywhere! This Stealthbox works great with the Seamless Sump, or any other sump system. The H2Overflow Stealthbox® has 1200, 2400, or 3600 gallons per hour capacity!

Siphon Stopper® Return Nozzle
The patented Siphon Stopper® return fitting allows you to minimize the risk of a back siphon and at the same time minimize evaporation, easily manipulate your water flow, and most important, no more reliance on failure-prone check valves! It works great with the Seamless Sump® System, and the Loc-Line nozzle gives you tremendous versatility. The Siphon Stopper® return fitting is the most reliable, unique, visually appealing approach to returning water to your custom aquariums and protecting your property.

Unstoppable Hopper® Feeder Extension
Our custom extension for the EHEIM TWINfeeder elevates the feeder above the surface of the water, so food does not get wet and clog the feeder. The hopper extends the pellet food quantity to last over 12 weeks with a typical well-stocked tank!

Custom Cages
We also make cages! Custom Cages, our sister company, manufactures a wide variety of built-to-order bird, reptile, and small animal cages! Our cages are endorsed by Jack Hannah of the Columbus Zoo & Aquarium and used by zoos all over the world, both large and small. Nobody has a unique, wide array of options to meet your specific cage needs like we do!
