    ive only had this tank under my ownership for a bout a month or 2 its the evo 13.5 gallon. the aquaticslife 115 skimmer came with the unit and worked fine (kindof) I had to install two zipties to the skimmer housing for it to work properly. anyways I have a oil film on the surface of my water. what do you think I should do? p.s. I didn't search for any sticky or bumped threads; feel free to rrecommend any links :)

    Could be oil from excessive feeding (the food) and/or a lack of surface agitation....just my guess

    Try to avoid getting your hands in there, even after washing, your skin oils will get in there. I think the only way to get rid of the oil would be an overflow that eats up the surface. What I did before my overflow when i noticed this was get a gallon bottle and have the power-heads only on one side on that way all that oil was pushed to the opposite side, then i used the bottle to collect that top layer of oil.

    It could be the selcon, try cutting back on that

    point your power head towards to surface to see if that helps

    I have a still, freshwater betta tank and get some oils on the surface from food. I lay a dry paper towel on the surface occasionally and it soaks up quite a bit of the oil. Good, cheap, quick fix.
