The tank has been up for about a week a half, but I didn't start adding food until about 5 days after it was set up. I did use vinegar to try and get the white stains off the glass at the top of the tank. I thought I rinsed good enough though. I haven't seen the bubbles forming, but I am sure they're coming from the filter. However, they didn't start until after I got most of the film off the water. With the food, I am allowing it to float, and last night I could see the rainbow colors of a protein film. It's just odd that the slimy water and thick film happened before I put any food in at all.
I over-use water conditioner all the time! First time I've had bubbles though. But when I do water changes, I use a gallon jug-add a few drops of conditioner-and then put it straight in the tank. Then once all the new water is in, I do a little bit less than what is required for the full amount of the tank. I was told to do this by someone on here.
I think this filter is a tetra whisper 2-10i, but I've never seen any settings on it???
