Oily Film On Water Surface

[saz326]

Get a sheet of newspaper and drag it across the surface. This should remove the oily film. It is usually caused by the food you are feeding.

Seconded.

If you are quick the paper wont even have time to get saturated so it will stay fairly rigid.

I just carried out a water change which seemed to leave most of it on the side of the tank as the level went down. Used kitchen towel to wipe this off then topped up water. Pump outlet aimed higher so increased surface agitation and problem solved!
