- Sophisticated design: The floating feeding ring ensures natural food distribution without the need for technical aids. It minimizes pollution caused by leftover food residues and helps maintain a permanently clean water ecosystem. - Durable and safe: Made with advanced 3D printing technology to create a smooth surface that resists deformation. This provides long-lasting stability and is aquarium-friendly, with no sharp edges or risks for fish. - Universal use: The design prevents drifts caused by water flow. It is easy to clean and includes a hook attachment for flexible placement in varied tank layouts. - Ecological safety: A closed material circuit guarantees contamination-free fish keeping zones and maintains an optimal oxygen balance during continuous operation underwater. 2-3 practical use scenarios - Scenario 1: In a community freshwater tank with small pellets or flakes, the floating ring distributes food naturally to all inhabitants, reducing uneaten leftovers and water pollution. - Scenario 2: In tanks with strong currents or active powerheads, the device stays in place thanks to its design and the hook attachment, preventing food from drifting away from fish. - Scenario 3: In breeding, quarantine, or delicate ecosystems, the closed material circuit minimizes contamination risk while maintaining good oxygen balance during prolonged use under water.
