This stuff is growing in my tank, and the fish seem unphased by it. The Ammonia, Nitrate, and Nitrite levels seem fine. The temp is right and the PH is right. WHAT IS THIS?

When I had that stuff, I had nitrites. What are your actual test results?

0 ppm Ammonia
0 ppm Nitrite
10 ppm Nitrate

Actually Nitrate could be between 15 to 20 PPM.

Its some sort of mold or fungus. It needs some organic matter to feed on, little particles of uneaten food most likely. I've had it grow on wood I was trying to soak.
