I think my tank is contaminated. I see small speckles and smears on the glass walls of my tank, and also, when I stick my hand in the tank, I notice that I break an oily film of some sort. The marks can be easy rubbed off by my fingers and the film keeps coming back when I change my water.
I am thinking that when i'm doing my water changes, and adding prime to de-chlorinate, it is mixing with the stress zyme bacteria. Any other clues?
