No offense taken, the filter isn't a permanent item just temporary. But why do you say it is bad? Do you have experience with this model?
Yes I do. That filter is usually included in Tetra combos. I bought a halfmoon plastic acuarium ( back when I didnt know better) and it was inluded in it. Its very good at collecting deitrus and getting cloged, its more of a gimmik than a real filter. Theres is no biological filtering, which makes me believe your tank is not fully cycled. Get you hands on a Aquaclear 20, or a Zoomed 501.
