Hi, i am looking for a replacement skimmer for my 120-gal. I had a Bubble Magus BM series and the pump just went up a couple weeks ago. According to Bubble Magus they no longer make the replacement pump and the recommended replacement pump requires an upgrade kit that is no longer available.... so, i am looking for a new skimmer and figured i would try here first. I would like to stay in the $200 to $250 range and i need an internal (inside sump) style pump. i believe i have a medium to heavy bio-load system. Any suggestions is greatly appreciated.
