My fish got in the way of the picture lol. Only the top is cloudy and the rest of the water is fine. I tried a water change a few days ago but the stuff just came backWhat's the picture of?
If it's the aquarium, try tank a picture from the front of the tank.
Milky cloudy water is caused by a bacterial bloom, and is common in newly set up tanks, or tanks with a lot of uneaten food in. A big water change will usually fix the problem.
Not necessarily, even with aeration it will still appear, the only way to get rid of it without active maintenance is with an overflow or surface skimmer, and sometimes the overflow doesn't work.Is there any aeration/ surface turbulence in the tank?
If not, then it's just an oily film that appears in tanks without aeration. You can try running a piece of tissue or paper towel across the surface. Or invest in an airpump and an airstone, and add some aeration to the tank.
