Questions for anyone running a Deltec hang-on skimmer MCE 300 or 600

[Black Phantom]

I've been running the 300 on my 50 cube for about a year know. It pulls out a lot of stuff which means you have to clean it quite often. A little bit finicky but easy to do.
Because the pump housing is in the skimmer it's quite quiet. I have it in the TV room with no problems. I did stick a thin rubber sheet in between the skimmer and the tank as I was getting a little vibration at the start.
I would say it's a good buy.
