Hi there,
I have a quite new tank (couple of months old). It has a capacity of 30 L and contains a total of 4 fish.
Recently a sort of oily film started to appear on the surface of the water, what is it? I do 30% water changes and I vacuum the gravel weekly.
What am I doing wrong?
The water is also a bit cloudy at the moment, could it be a bacteria bloom? Please help!
