I guess I have a little free time today because I finally got around to asking this one. Been wondering about this stuff for ages now.
I use coarse ARM reactor media and it usually have this stuff in it. I have always been a little concerned about the purity of what gets dissolved in my reactor. This stuff just seems odd. Anyone know what the dark stuff is. On the right is the normal looking white stuff
