XEWEA Mini Aquarium Air Pump New Double Sound Insulation Ultra Silent Oxygen Air Pump Aquarium with Air Stone Check Valve Air Tube One Outlet 10L 60L

Warm Tips: 1.The pump is NOT SUBMERSIBLE, please do not put it into aquarium. Keep it dry. 2.No check valve, the air pump should be placed above the water level of the fish tank?about 25cm?. 3.With check valve, the air pump can be placed below the water surface or placed on the table. The check valve (note the installation direction) can prevent the water from flowing backwards. 4.Please put the air stone into water to soak for 15-20 minutes before you connected it to the air pump, so that bubbles can emit all around. 5.To get the maximum air flow and extend air pump service life, we suggest to clean air line tubing and airstone regularly.
