In the last couple of days it has slowed down.
I first thought it was Red Slime Algae, Because it looked kind of red, but after talking to the LFS
they said If I could blow it off with a turkey Baster then it was Diatoms not Red Slime.
All of it blows off, and is kind of powdery when scraped off the glass. It is also real stringy if left to grow.
