I am looking to get a protein skimmer for my 20 gallon reef tank. I am looking at the Remora or Bakpak, but I have heard different things on each of them. I want one that is quiet since my tank is in the middle of our dining room. I would prefer to have one that doesnt give off a lot of bubbles either. I don't have a sump, so I think it will have to be a HOT. Any suggestions for a rookie from some veterans?
