Product Overview Maintaining clean foreground slopes and evenly layered aquasoil requires smooth, controlled substrate shaping. The UNS Grey Flattener (10" / 25cm) offers a dual-ended spatulate design for leveling sand, gravel, and plant soil in aquascapes. Precision-crafted from rust-resistant stainless steel with a satin grey finish, this 10-inch substrate flattener features a wide paddle for rapid foreground grading and a narrow tip for detailed work around rocks and driftwood. The double-ended profile accommodates both large aquarium displays and delicate nano layouts with balanced hand control. Key Features & Benefits Dual-Ended Spatulate Design: Features a broad blade for leveling wide open substrate beds and a slim opposite blade for detailed work in narrow gaps. Substrate & Slope Precision: Effortlessly smooths cosmetic sand foregrounds and bank aquasoil slopes to establish visual depth in planted layouts. Medical-Grade Stainless Steel: Forged from high-grade, rust-resistant materials for long-lasting structural rigidity during heavy substrate grading. Satin Grey Protective Finish: Formulated for high corrosion resistance and an industrial, non-glare aesthetic that complements any aquascaping toolkit.

Why use a sand flattener instead of leveling substrate by hand or with a card? A dedicated 10-inch sand flattener provides extended reach inside filled aquariums, allowing you to work without submerging your hands or disturbing the surrounding hardscape. The stainless steel blades provide rigid, precise control for creating steep depth perspectives and smooth foreshores that plastic cards cannot achieve. 2. Can I use this tool while the tank is filled with water? Yes. The UNS Sand Flattener is made for both dry hardscape setups and underwater maintenance. It glides through filled sand beds easily to fix disturbance caused by bottom-dwelling fish or water changes. 3. Will the satin grey coating scratch or peel off over time? No. UNS tools feature an inert, aquarium-safe protective finish engineered specifically for aquatic maintenance. It will not peel, leach, or affect water chemistry. Avoid using abrasive scrubbing pads when cleaning to preserve the finish.
