Xinyou XY-380 Super Biochemical Sponge Filter

This is the retail packaging for the Xinyou XY-380 Super Biochemical Sponge Filter, a high-capacity, air-driven internal submersible aquarium filter. Known for its durability and reliability, this large-scale biological filter is an ideal choice for larger fish tanks, fry-rearing setups, shrimp colonies, and professional breeding installations requiring gentle yet efficient filtration.

​Detailed Description

​Packaging & Branding: The product is housed in its signature light green and white striped cardboard box, featuring the prominent XINYOU brand name in bold red text outlined in white. The front face shows a crisp product photo of the standalone thick black foam sponge setup alongside an illustrative graphic of thriving community fish swimming near vibrant aquatic plants.

​The XY-380 Advantage (Compared to XY-280): * Expanded Surface Area: The XY-380 is a physically larger unit featuring a wider, denser sponge block. This provides a significantly larger surface area for both debris collection and beneficial bacterial colonization.

​Higher Tank Capacity: This model is designed for larger aquariums (typically rated for tanks up to 40–50 gallons depending on the tank's biological load).

​Filtration Mechanism:

​Mechanical Trapping: The high-quality, porous black sponge filters out physical waste particles, uneaten food, and floating debris, greatly improving optical water clarity.

​Biological Cycling: It acts as a massive breeding ground for beneficial nitrifying bacteria, ensuring a stabilized nitrogen cycle by converting harmful fish waste (ammonia/nitrites) into safe elements.

​Key Safety Features:

​Fry & Shrimp Safe: Because it does not rely on a powerful motorized impeller intake, it poses zero risk of sucking in delicate baby fish, shrimp, or small inhabitants.

​Maximum Oxygenation: Operates cleanly via a connection to an external air pump, constantly churning out fine bubbles that break the water surface to maximize gas exchange and oxygen levels.

​Solid Anchor Base: Comes equipped with a heavy, weighted black plastic bottom rim that keeps the filter firmly placed on the bottom of the tank without floating up.
