Just a little off the top please....

My AquaC Remora skimmer has been a very reliable and efficient HOB skimmer.  Here is some video footage of it in action.  As you can see in the video, the skimmer can be a little noisy.  There is a trick that I saw online, (I don't recall where) on how to quiet down the skimmer substantially. 

Here is what you will need for the silencer:

• Plastic lid (like from sour cream or butter)

• Flexible aquarium airline tubing

• razor blade

Take the collection cup and set the square foot of the cup onto the lid of your choice.  This foot is the same size as the chamber on the left and right of the skimmer.  Mark around the foot so you can cut out a similar size rectangle. 

Next, cut pieces of airline tubing long enough to go around the plastic piece you have.  You will have 4 pieces total when complete.  Lastly, you use the razor blade to carefully cut a slit down the side of the airline tubing lengthwise.  Then slide the tubing around the piece of plastic.  I will post a video eventually showing exactly how to do this.  Feel free to ask any questions!
