The JBJ Aquarium Reaction HOB Aquarium Power Filter is a slim hang-on-back power filter. With its quick startup, silent operation and easy maintenance, the Reaction HOB power filter is the perfect choice for filtering your aquarium water. With its three-stage filtration—mechanical, biological and chemical—this filter will keep your aquarium water clean and healthy for your fish. It features an innovative dual intake system and a flow control valve that allows you to change the flow rate. The self-levelling surface skimmer intake helps rid your tank of sludge and surface film and keeps your aquarium surface free from floating debris. The pre-filter sponge provides protection for smaller fish, and also keeps shrimp from being pulled into the filter. Simply hang this filter on the back of your aquarium and let it do its work!
