Blue Marine Silencer is a compact yet highly effective accessory for aquariums equipped with overflow systems, sumps or gravity‑fed drain pipes. In such systems, air mixing with draining water often causes loud gurgling or sucking noises.

The silencer is installed directly inside the drain pipe, where its spiral design guides the water smoothly downward. This reduces air intake and stabilizes the flow, significantly decreasing noise without adjustments, electricity or moving parts.

Made from durable plastic, the silencer is suitable for continuous use and is especially beneficial for aquariums placed in living rooms or bedrooms where quiet operation is essential.

Three sizes available
