The 100 Gallon Fish Tank

(48″L x 18″W x 24″H)

This glass fish tank is comprised of 3/8″ glass with our patented frame on the top and bottom of the tank. The frame is made from high-strength black anodized aluminum.

Rigorous quality control goes into the glass of every Custom Aquarium. We remove integrity-compromising micro-fractures by beveling and polishing every edge of every piece of glass. We also use a black, high-strength silicone that is 5x stronger than common clear aquarium silicone.


The Basic Package

The Basic Package includes everything you need to connect a sump filtration system to your aquarium. It includes (1) H2Overflow® overflow screen and (2) Siphon Stopper® return nozzles. Holes for the overflows and returns are drilled in the back of the tank, giving you a low-maintenance, gravity-fed sump system that is much less likely to fail or flood.


The Deluxe Package

The Deluxe Package adds a 1200GPH 46 Seamless Sump filter system. The sump system will hold around 31.9 gallons of water bringing your system volume to about 116.9 gallons. The Seamless sump tubs are made out of durable high-density polyethylene and have no seams that can leak or fail.

This Seamless sump system includes (2) Sicce 1.5 return pumps for redundant returns if one fails. The system also includes a UV sterilizer, bio media, Purigen, a filter sock, and all the return and overflow hoses.


The Ultimate Package

The Ultimate Package includes a substrate, plants, a heater, a bubble wand, an air pump, and cleaning and maintenance supplies. This is the fastest way to get everything you need to get your aquarium up and running.



The Majestic® Stand

Design your own Majestic® Aquarium Stand! Each stand is either made of powder-coated steel tubes or a hardwood cabinet with a matching canopy! Hardwood stands and canopies are available in various styles, woods, and colors.

Our Majestic® stands are built to last a lifetime, so we never use cardboard, fiberboard, particleboard, or softwood.

The steel stand is made from high-strength square tube steel welded into a single solid piece. The whole frame is finished with a durable oven-cured powder coating. It also has a 3/4″ plywood top that’s painted to match the black powder coating.

Why Choose A 100 Gallon Fish Tank From Custom Aquariums?Custom Aquariums Aluminum Frame

Anodized Aluminum Frame

Our proprietary aquarium frame is the strongest and most advanced on the market. Each frame is made of anodized aluminum and is significantly stronger than plastic or euro bracing. It will never rust, corrode, or become brittle from salt and light exposure.

This 100-gallon fish tank has a center cross brace that keeps the front and back panels from bowing out. It can be easily removed for aquascaping when the tank is empty.

Custom Aquariums beveled glass corner

Precision Glass

We use thick glass panels for our aquariums, beveling and polishing 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.

Custom Aquariums high strength silicone

High Strength Silicone

The reliability of an aquarium depends on the strength of its silicone bonding. Our aquarium-grade, black silicone is five times stronger than standard clear silicone.
