There's been an oily residue on the surface the last couple days, so last night I did a water change and cleaned out the canister filter really well, but today I noticed it is still there. Not sure if I am doing something wrong (and my tank is in imminent danger), if this is a normal part of the process, or what? Anything I should do? Thanks much!
Welcome! things builds up on the surface due to lack of surface agitation and is an easy fix. so just keep the surface moving (does not need to be too much) to prevent silt from building up
