I am new to the idea of a wet dry filter on a planted tank. I run a 180g and am constantly fighting a protein slick. I get how the skimmer box would remove the oil, but what is going to prevent it from being sent right back into the tank? It isn’t the bio balls... is there a particular filter media I should be using on the “wet” side before the return?

Typically using a filter sock will capture the oily film.
