so I have the small oceanic bio cube skimmer that came with a 12G setup, seemed okay at first but now I noticed this brownish gunk build up around the wooden piece, anyone experienced this before? Seems to build up every week, stains the wood dark.

the oceanic one pissed me off.
What other skimmer could I replace it with in a tank that size? That can fit in one of the back chambers.
