The Waterbox Clear MINI 20 is a premium, small-format rimless aquarium designed for aquascaping enthusiasts who demand absolute clarity in a compact footprint. Measuring 450 x 450 x 400 mm, this "cube-plus" geometry offers a generous depth-of-field for its size, making it a favorite for high-end Iwagumi or Nature Style planted layouts. Constructed with Starphire Ultra-Clear™ glass on all panels, the Clear MINI 20 removes the distorted green tint found in standard glass, providing a crystal-clear window into your aquatic environment.
The Clear MINI series is built to the same exacting standards as Waterbox’s full-sized reef systems, scaled down for desktops, offices, or bedrooms.
Starphire Ultra-Clear™ Glass: Features 6 mm low-iron glass with high light transmittance, ensuring that the colors of your plants, shrimp, or fish are seen exactly as they are.
Laser-Applied Silicone: Utilizing high-quality German silicone, the seams are nearly invisible and applied with extreme precision to maintain the minimalist "floating water" look.
Pre-Installed Self-Leveling Mat: Every Clear MINI 20 comes with a black foam leveling mat pre-attached to the base, protecting the glass from stress points and ensuring a stable foundation on furniture.
Beveled Edges: The edges are meticulously straight-edged and then beveled to provide a smooth, premium feel and added durability against chips.
Versatile Open-Top Design: The rimless architecture allows for the use of "clip-on" LED lighting and various filtration styles, from internal corner filters to external canisters.

Is this aquarium suitable for a saltwater reef?
Yes! While popular for planted tanks, the Clear MINI 20 is frequently used for "Nano Reefs." You will simply need to add your own filtration (such as a hang-on-back filter or a small canister) and a reef-capable LED.
Does it come with a lid or cover?
The Clear MINI series is sold as a rimless, open-top tank. If you have "jumpy" fish, you may want to purchase a custom mesh or glass lid separately.
What kind of stand do I need?
At 81 liters, the tank will weigh approximately 100 kg (220 lbs) when full. It should be placed on a dedicated aquarium stand or a piece of heavy-duty, solid wood furniture that can support the weight without bowing.
How do I clean the Starphire glass?
To avoid scratches, always use a soft microfiber cloth or a dedicated acrylic/glass-safe magnetic cleaner. Avoid using abrasive pads or standard household glass cleaners.
ONF Flat Nano LED: A stylish, high-output LED light that clips perfectly onto the 6mm rimless glass of the MINI 20.
Oase FiltoSmart Thermo 100: An external canister filter with an integrated heater, perfect for keeping the inside of this rimless tank looking clean and equipment-free.
AquaRIO Neo Glass Pipes: Ultra-thin glass lily pipes to maintain the minimalist aesthetic of your filtration intake and return.
