That's the reason why I cam using gravel from my 55 in my ghost shrimp tank. I was hoping that there'd be sufficient microorganisms in the gravel to get into the water column. If not, I may have to use green water or something like that. Maybe some pond or lake water would work if the green water doesn't. I'm just going to see what happens without adding anything though.
