Title: Just poor quality
Review: It is sad to think that these filters are so dismal. They vary greatly from the cartridge included with the filter.The included filter cartridge is thick and translucent. These cartridges are thin and almost transparent. I worry that if I were to use the carbon in these filters pieces may fall into my aquarium.As it stands I have two packages of these and I will probably use them minus the carbon. It is really sad that the preassembled quality is astoundingly different from the rags that these are.
