Don't use calcium ! that stuff is horrificly corrosive !!! Use a good base material such as pond silt and then stiffin it up with gypsum or lime, lime gives a bit more grip if you get the coarse ground stuff. It will be like racing on 80 grit sandpaper ! And it will lighten up the soiil color so the blue groove shows up very fast
