Precautions 1. Put the water inlet into the aquarium 2. Do not drain the water completely during use Place the outlet water below the fish tank 4. Keep pressing the blue water-absorbent ball, and stop pressing after the water flow is formed, then the water can be changed and cleaned. 5. Because the filter has a pore structure, too fine sand will be sucked out. Tighten the outlet pipe to control the water flow. Avoid this kind of situation.
