Hang on skimmers

[VFX]

I've owned 2 MCE 600's before. Really great skimmers, but can occasionally get a bit noisy if you don't keep them clean.

I'm currently running a Tunze 9002 Nano Doc in my 15 gallon. Not a HOB, more an in-tank skimmer but it's so small you barely notice it. It's also whisper quiet, in fact it's probably the quietest skimmer I've ever had.

Both are extremely hard to find 2nd hand though, which probably means people tend not to part with them.
