Description

This Aquarium Package is designed specifically for our 120-gallon glass fish tank. The tank and filter is a passive, gravity-fed system with redundant pumps for a low maintenance, efficient, and reliable setup. Safety measures are already taken into account, optimizing the following processes:

  • Circulation
  • Aeration
  • Water Flow
  • Skimming capacity
  • Surface area of biofiltration

We offer multiple packages from the Fish Tank Only to the Ultimate Package (more details below). See which provides the best value to set up your freshwater, saltwater, reef, or marine aquarium! And remember, the higher the package level, the higher the savings!

Plus, if you order it with a custom fish tank stand, you’ll receive a LIFETIME Warranty on your aquarium.

 

The Fish Tank

(48″L x 24″W x 24″H)

This 120-gallon fish tank is made from 3/8″ glass with our patented frame on the top and bottom of the tank. The frame is black anodized aluminum and held tightly to the tank with high-strength silicone.

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 and the silicone we use 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, such as (1) H2Overflow® overflow screen and (2) Siphon Stopper® return nozzles. We drill holes for the overflows and returns in the back of the tank creating a low-maintenance, gravity-fed sump system that is much less likely to fail.

 

The Deluxe Package

The Deluxe Package adds a 1200GPH 45 Seamless Sump filter. The sump system holds around 31.9 gallons of water bringing your system volume to 142 gallons. Seamless Sump tubs are made of high-density polyethylene, one of the most durable plastics, and have no seams that can leak or fail.

This Seamless Sump system includes (2) Sicce 2.0 return pumps for redundant returns if one fails, a UV sterilizer, bio media, Purigen, a filter sock, and all the return and overflow hoses.

 

The Ultimate Package

The Ultimate package includes everything in the previous packages, plus items for the interior of the tank. These include a substrate, plants, a heater, a bubble wand, an air pump, and many cleaning and maintenance products. Everything you need to get your new aquarium up and running.

 

The Majestic® Stand

Design your own Majestic® Aquarium Stand! Each stand is 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.

We build our Majestic® stands to last a lifetime, so we never use cardboard, fiberboard, particleboard, or softwood.

The steel stand is a collection of square tubes welded into a single solid piece and the whole frame is finished with an oven-cured powder coating. It also has a 3/4″ plywood top that we paint black to match the powder coating.

 

Why Choose a Fish Tank From Custom Aquariums?

We’ve been building aquariums for over 20 years and we’re now the largest manufacturer of custom glass aquariums in the USA. Learn a little more about our fish tank frame, precision glass, and high-strength silicone that keep each Custom Aquarium in service for a lifetime.

Custom Aquariums Aluminum Frame

Anodized Aluminum Frame

Our black anodized aluminum frame is the strongest most advanced frame on the market. It’s significantly stronger than plastic or euro bracing and it’ll never rust, corrode, or become brittle from salt and light exposure.

This 120-gallon fish tank has a center cross brace that keeps the front and back glass panels from bowing out. Easily remove it for aquascaping when the tank is empty.

Custom Aquariums beveled glass corner

Precision Glass

The glass we use is thicker than most of the competition. We also bevel and polish every glass edge, even those 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 strength of an aquarium depends on the strength of silicone bonding, which is why our black silicone is 5x stronger than standard clear silicone.
