The Sera tube is made from top-quality materials that do not contain harmful plasticizers, ensuring that the water remains safe for your fish and plants. Its composition is designed to withstand pressure and temperature changes, preventing the formation of cracks or hardening over time. With a wall thickness that ensures the preservation of its cross-section (approximately 0.16" per side), it offers a steady flow without the risk of kinking that could strain your pump.

The grey color of the tube offers a significant advantage compared to transparent tubes: it drastically limits the growth of algae inside it. The reduced light permeability prevents the photosynthesis of microorganisms, keeping the tube clean for a longer period and ensuring maximum performance for your filter. Additionally, the neutral grey color harmonizes perfectly with the aquarium equipment and the back of the tank, providing a more professional and "tidy" visual result.

With standardized dimensions of 12/16mm, this hose is fully compatible with the majority of external filters on the market, as well as accessories such as Lily Pipes, CO2 systems, and UV Sterilizers. Its surface allows for easy attachment to fittings and connectors, ensuring complete watertightness without leaks. It is available by the meter (price per 1m), allowing you to purchase exactly the amount you need for your custom installation, reducing unnecessary joints and pressure losses.
