Ok so tonight I emptied the tank of all water and CC. Got into into position in the living room. I cut my eggcrate to size, leaving about an inch around the edges, so not to touch the silicone. I started digging through my sand to fill in the first layer and to cover the eggcrate.
I noticed some of the sand is a greyish color while the rest is whitish tan color. It also smells a bit nasty. The rest smells fine. Could this have been the bottom layer from the previous tank? And should I throw this darker stuff out?
