Up Aqua's Bottom Circular Bar is used to create reverse flow filtration, biological reactors, or planted beds. It can be used with many different types of filtration such as an air filter, powerhead filter, top filter, sponge filter, and rain bar units. These filters provide double filtration to make water crystal clear and to obtain optimum filtration. The bottom circular bar is easy to assemble and flexible enough to fit most aquarium sizes. It is also suitable for both freshwater and saltwater aquariums.
The circular bar improves the circulation of oxygen in the bottom layer of the aquarium and helps to maintain a good environment.
The bottom circular bar should be used with a surface air pump and a submersible air pump. It also regulates the water current of a saltwater aquarium and lessens the oxide of the nutritious salt.
