About This

• Automatic mode uses tank flow to collect substrate-surface debris and floating fine particles when they are guided toward the inlet. It does not pull debris from every area by suction alone. Performance varies by placement, flow direction, and fish species.
• Handheld mode is designed for surface cleaning only: Move slowly along the substrate surface to remove visible debris. Do not stir or disturb the deep layer.
• Recirculating filtration keeps water in the tank: Water returns to the aquarium while debris stays in the sponge filter. Remove waste without draining tank water.
• Air-lift suction reduces crushing: Lifts debris without crushing it to help reduce cloudiness. Powered by an air pump recommended at 1.5 to 2 W. Air pump not included.
• Critical setup + size selection: Choose by water depth from substrate to surface — Small (7–10.6 in), Medium (10.6–17.7 in), Large (13.8–23.6 in). Keep the sponge filter fully submerged and positioned about 0.4 inch below the water surface.
• Sponge cleaning: Use tap water, and always knead the sponge underwater. The 60 PPI high-density sponge captures fine particles, so clogging can reduce flow. Kneading helps flush out buildup and restore flow. Replace the sponge if flow does not recover after thorough cleaning.
