Graphite shaft cover. Durable wear resistance. Low DB Operation. Needle wheel impeller generates fine and smooth bubbles. Integrated molded cast acrylic skimmer body. Solid construction and long-life service. Three places to tune the skimmer, easy operation and better reaction. The pump will run at a low speed within 30s just after the power is on and then speed up gradually. Just to prevent overflow after the sudden power-on. Overflow may occur during dial-in period. Adjust the air intake and the water outlet to reach the appropriate water level. After that, the water level will drop. And it needs to be adjusted again. As the surface tension of the bubble is constantly changing, this operation may need to be repeated several times before the skimmer breaks in. It usually needs a couple of days to one or two weeks. After that, adjust the air intake and water outlet slightly to achieve stable performance. There are three places to tune the skimmer. 1. Move the skimmer body up and down to adjust the aquarium water level to the recommended water level line marked on the skimmer body. 2. Rotate the air intake valve to adjust the air volume. It is recommended to turn it to its maximum at the beginning. 3. Rotate the collection cup which is connected with the inner tube to adjust the water outlet. This process requires patience, as a small amount of adjustment can cause significant changes in the water level inside the skimmer.
