Why Choose Custom?

Custom Dimensions

The #1 reason for choosing custom is size. The dimensions of your custom aquarium are completely up to you. We give you the ability to design your aquarium in a size you've always dreamed of.

Overflow Placement

The position of your overflow can make a huge difference when deciding how your want to design your aquarium. Choose from central, island, external or full-width style overflows.

Rimless or Euro Braced

Bracing provides extra durability on larger aquariums, but rimless provides a clean, modern asthetic. Choose from rimless, euro or regular bracing. 

Standard or Peninsula

Choose either standard or peninsula-style to best accommodate your space. The standard configuration is for placement against a wall, while a peninsula divides the room.
