wierd film....
...since yesterday i noticed a film of some sort on top of the water. the water is clear and clean, but you can notice this looking from the top down. it's like "oil and water" i tried to stir it but it doesn't do anything, just sits on top of the water. anyone know what this could be? i would post pictures, but i'm at work and i really don't know if you could notice it in the pictures. any suggestions on what it is and what can i do?
