The EHEIM Quick Vac Pro is a battery-powered automatic gravel cleaner that simplifies substrate maintenance in both freshwater and marine aquariums. With no hoses or buckets required, the device uses suction to lift debris and sludge from the gravel while returning the water directly to the tank—preserving beneficial substrate structure and reducing disturbance. A reusable super-fine mesh cartridge captures waste particles, and the unit is fully submersible (up to approximately 90 cm). Ideal for intermediate cleaning between water changes, though it is not recommended for use with very fine sand or ultra-fine gravel.
