Little black hairs

[Jasoncwrd2002]

So I believe my tank has cycled and I've been noticing all these little black looking hairs on my glass. I attempted to clean once and it just floats when I scrub it. My back glass has it all over and front has it also. What is it and best way to get rid of it? I'm thinking when I do a water change to knock it loose while suckitioning the water at as best as I can. Also diatoms are still in the sump box that hangs in the water and on the sand. I've read that it goes away

I had the little black hairs on my rock and sand. I cleaned what I could and cut back on feeding and light cycles. My Foxface ate a lot of it. Just takes time.
