I have a pond type setup and noticed the surface of the water is oily. I think it is natural from the food fish. My question is can I remove oil on top of water with anything? Water changes help but during a water change the water is being taken from below the oily surface. Thanks. tp

That actually stop me from feeding my fish smelt cause it makes the top water of my tank oily too.
