What Are Custom Aquariums? – A Complete Beginners Guide
You may not realise it, but custom aquariums are around you all the time. It may be in a fancy restauraunt up in London, or perhaps you have seen an aquarium built seamlessly into someone’s wall. Unlike standard off-the-shelf tanks, these systems are designed with style and purpose in mind.
In this beginner’s guide, we’ll break down exactly what custom built aquariums are, how they work, and whether they might be the right choice for you.
What are Custom Aquariums?
Custom Aquariums are essentialy bespoke built fish tanks, they’re designed to meet specific requirements, rather than being mass produced in a standard range of shapes and sizes. The beauty of designing one from scratch, is that you can fully tailor it to your needs rather than working around factory set design, limiting your capabilities.
These aquariums can be:
- Built into furniture and walls.
- Designed into unique shapes like “drop-off” and “room dividers”.
- Created to match interiors, bringing a room to life.
- Built on site if access is an issue
In short, they are aquatic ecosystems that combine functionality with visual impact.
How Are They Different From Standard Aquariums?
Custom built aquariums are unique because they offer you flexibility and customization, thats not to say they might be right for you… Let’s weigh up the options
Standard Aquariums:
- Come in set sizes, (e.g., 50, 150, 350, 700 gallons).
- Limited Design options.
- Lower upfront cost.
- Consistent availability.
Custom Aquariums:
- Designed to fit into your designated area.
- Higher Cost – longer wait time.
- Professionaly installed and commisioned.
- Fully customizable with the option to add unique technologies and features (45 degree mitred corners, one piece euro brace)
If standard tanks are like buying furniture from a store, custom aquariums are like commissioning a bespoke piece made just for your home.
