The F-Zone Anata Cube Aquarium
I recently had the opportunity to work with F-Zone, a company that recently launched its own line of aquariums. I'm using their 20-centimeter Anata cube aquarium for this project. This small cube is made from high-quality Optic White extra clear glass with 45-degree beveled edges, giving it a sleek and modern look. The included black backing adds a nice touch.
The build quality is impressive; each tank undergoes a 72-hour leak test, ensuring a leak-proof product. This level of quality control is reassuring for any aquarist. It's available in various sizes, making it suitable for various projects, from small shrimp tanks to larger setups.
Lighting and Layout Inspiration
For lighting, I'm using a small LED light I had on hand. It provides ample illumination for this small setup. My aquascape design is inspired by a previous 20-liter cube tank I maintained. It featured a simple yet elegant hardscape: two pieces of wood, lava rocks, and densely planted with fissidens moss.
I'm reusing the same two pieces of wood from that older setup; they've been in storage for a while, but with some light and fertilizer, they'll regain their vibrant green color. I'm excited to revisit this classic layout in a miniature scale!
Hardscape Construction and Gluing
The two pieces of wood are positioned in opposite corners, creating a 'V' shape. Lava rocks are used to elevate and secure the smaller piece of wood and provide a natural look. The porous nature of the lava rocks provides beneficial bacteria habitat for a no-filter system.
To ensure the stability of the hardscape, I used the cotton pad method with super glue and baking soda. Small cotton pads are inserted between the wood and rocks, saturated with super glue, and reinforced with baking soda. This creates a strong, secure bond.
Substrate and Planting
I use Rio Wetland Eonie (crushed black lava rock) in the back, providing additional bacterial habitat and nutrients. This is layered with aquasoil, which provides the bulk of the nutrients for the plants. I am using several types of plants including Eleocharis, Glossostigma elatinoides, and various moss species.
The Monte Carlo, unfortunately, was in poor condition due to prolonged storage. It's replaced with moss from another tank to better fit the layout. The planting process involves carefully placing the plants amongst the hardscape and substrate.
Filling, Finishing Touches, and Stocking
After planting, the tank is carefully filled with water, and any excess soil is siphoned out. Cosmetic sand is added to the foreground to complete the aquascape. The final touch is adding five Carolina shrimp, and a few ramshorn snails.
The aquarium is left to establish for a month. The resulting aquascape is a miniature replica of the larger design, showcasing the beauty and practicality of a no-filter setup.
No-Filter Aquarium Tips and Conclusion
Successfully maintaining a no-filter aquarium relies on regular water changes (especially during the initial weeks), a porous substrate for beneficial bacteria growth, and dense planting to act as a biological filter. This helps keep the water clean and clear.
While heaters aren't always necessary, they can maintain a suitable temperature depending on your room temperature and shrimp species. Overall, this mini no-filter aquarium is a stunning example of how a small footprint can create a beautiful and thriving aquatic environment with minimal equipment.
