The Chaeto is widely regarded for its filtering capabilities. It is basically green macroalgae that are extremely hard and can be kept by novice aquarists. The Chaeto doesn?t disintegrate in the tank, due to low lighting and low nutrients. Its propagation is very easy, as it can be kept and grown anywhere. The only thing it requires is the proper illumination, such as 2 watts per gallon, and that will help the Chaeto to grow faster. The presence of the Chaeto helps reducing phosphates and nitrates as well as other nutrients. Being extremely hardy, this Chaeto will thrive in many various conditions. As it cannot get attached with rocks present there, it can easily be harvested and removed if required. Unlike Caulerpa species of macro-algae, the Chaeto does not undergo sexual reproduction and release the nitrates back into the system causing a sudden crash. Also, this microalga is a great habitat for micro fauna such as Copepods and Amphipods to reside and populate.
