OF hangon filter with skimmer
 

Is anyone using this for their tank?
Is the skimmer good enough?

This filter only has a surface skimmer to remove the layer of organics that you would see on the water surface. Its function is different from the protein skimmer which removes dissolved organics within the water column. If the tank is small, you can just use this filter and do regular water changes. I would advise getting a protein skimmer if used on a larger tank.
