i know that i have asked about skimmers before, but I have a friend that has a brand new seaclone that he will basically give me for like $25. He realized that it isnt big enough for his tank after he bought it, and he can no longer take it back. are these bad skimmers because I have never heard anyone talk about them. is the pump even worth it???? If it is a skimmer that will work, i will buy it,
