Every biOrb aquarium comes with everything you need to get started—filtration, lighting, and air pump included. Just add water, choose your décor, and you’re ready to enjoy your new underwater world. No complicated parts, no guesswork. It’s nearly effortless from day one.
Our filtration system is located at the bottom of the tank (where waste naturally settles) for maximum effectiveness. It combines biological, mechanical, chemical, water stabilization, and oxygenation to keep your aquarium clean and your fish thriving.
Crafted from premium acrylic that’s up to 10x stronger and 23% clearer than glass. It offers brilliant visibility from every angle and helps insulate water temperature, adding stability to your aquatic environment all year round.
Every biOrb includes low voltage LED lighting. Choose from standard white LEDs or upgrade to MCR (Multi-Color Remote) models that let you shift between 16 colors and simulate natural day-to-night lighting cycles.

Its seamless 360-degree design offers an uninterrupted view from every angle, perfect for admiring your aquatic landscape in full.

Yes. biOrb aquariums come with everything needed for a freshwater setup. For a saltwater setup, you can adapt the Service Kit by removing the foam. You would then need to source the salt and hydrometer at your local pet store. If a higher-intensity light is needed, there are a few add-ons you could source. We recommend using an 8-gallon or larger biOrb aquarium but always consult your local saltwater aquarium shop for best results. See our tips and tricks for more details.
We recommend a simple cleaning routine every 4–6 weeks. biOrb aquariums feature an integrated 5-stage filtration system that keeps water clearer for longer, minimizing maintenance. With our Service Kits, replacing the filter is quick and mess-free. Just a few minutes of care helps keep your aquarium healthy and beautiful.
Yes, the biOrb CLASSIC is perfect for beginners and hobbyists alike. It comes as a complete kit with everything you need to get started, including a filter, air pump, LED lighting, and water treatments. Its all-in-one design removes the guesswork, making it easy to set up and even easier to enjoy.
The type and number of fish will depend on the size you choose:
We always recommend cycling your tank first and checking with your local aquatic specialist to make sure your fish are a good match.
The CLASSIC is our original and most iconic design, featuring a sleek, globe shape that offers a 360° view of your underwater world. While other biOrb lines (like TUBE or FLOW) offer rectangular or cylindrical styles, the CLASSIC delivers a timeless look with a compact footprint, perfect for desktops, entryways, or as a conversation-starting décor piece.
Each biOrb aquarium shares the same filtration technology, high-quality acrylic build, and easy-care promise, so you can choose the shape that best suits your space and style.
Not automatically. The MCR timer ends in a soft blue “night mode,” not full darkness. This setting is designed to mimic moonlight and provide a calming nighttime environment for your aquarium. If you prefer complete darkness, simply turn the light off using the remote or inline switch.
No, the timer function works with white light only. When you set a timer (8, 10, 12, or 14 hours), your biOrb will follow a natural white-light cycle starting in deep blue, rising to white, then returning to blue “night mode.” Colored lighting options must be selected and adjusted separately.
