This skimmer is for Hang-on use ONLY. It can be hanged on the back of the aquarium or the sump. But it can't stand in the sump on its bottom. The pump is submerged in water. But the skimmer body is outside the tank. As it's not a big skimmer, the volume of the reaction chamber is limited, patience is needed while adjusting to achieve the best effect. Read more Better design, Better performance. This IOAOI external hang-on protein skimmer adopts vortex inflow design, which differs from most mini protein skimmers. The vortex pushes the water from the bottom to the chamber faster and prevents from flowing backwards. More importantly, it generates more bubbles. Much denser foam and longer time contact. Better reaction. It therefore has outstanding performance. Beautiful waterfall outflow The water comes out from the chamber into the tank via a waterfall outflow. It creates a beautiful scenery for your tank. The murmur of water will also make you feel more peaceful. And it will also increase the oxygen capacity of the aquarium. Water flow adjustable The water flow can be easily adjusted by the knob to make the bubbles go into the collection cup perfectly. Or to prevent over flow at the beginning.
