I have a BMQQ...it's not in my nano yet as I needed to make changes to my sump to accomodate it but as a second skimmer in my main display it's been pulling awesome amounts of skimmate. One thing to note is that it requires a fairly deep spot to sit as the MJ1200 is mounted about 10-12 inches up from the bottom. That's why I have to make changes as my sump only has 8 inches of water currently.
For $69 including the MJ, I've been impressed.
