I have had my tank about a month and a half now. I am wanting to get a protein skimmer so I can introduce an anemone to my clown. I have one problem though. The lfs doesn't have a skimmer small enough for my tank unless I buy a canister filter to open the back up completely. I went on petco.com to see if they had anything and they do. They have a skimmer for just ten bucks for my size of tank. I just want to know if anyone has ever used one of these: Lee's counter current protein skimmer, or berlin air-lift protein skimmer. Also, when purchasing either one of these...I do need to get an air pump right? New to the subject so any advice would be helpful.
