Set Up for Hang-on Protein Skimmer
Hang skimmer on back of the aquarium.
Get a cup to fill main body with water up to the middle.
Bend the air intake hose so no air can get through.
While bending the hose, plug the electric cord into the wall. Wait until the water level reaches almost to the neck and then release the air hose. The skimmer should start running by now.
Water level can be adjusted by using the adjusting knob. Note: IF the water level is too high, it will cause the skimmer to overflow.
Maintenance
Clean the pump and air intake adaptor every 2 to 3 months to prevent calcium build up.
