Hey this is a totally dumb question. My 46g tank is suddenly having a oilly surface residue since adding a Korallia 2 powerhead and starting to feed my fish mysis shrimp. Is this from not enough flow skimming the suface, the Korallia 2 powerhead points more at a 45 degree angle toward the middle of the tank and the flow from the marineland c220 canister filter points downward also. Should i aim the filter flow more towards the surface? and I also just purchased an aquac remora skimmer with the maxijet 1200 yesterday, can't wait to get it! Thanks for any input.
