Hi all, Due to the excellent reviews flourite has gotten, I am going to try it out in a 10 gallon tank I am setting up. Can you help me to determine the best way to use flourite? Do I just use it as a prime substrate? Do I mix it with gravel? Do I use 1 layer gravel and one layer flourite? Do I use flourite/gravel mix and then a layer of gravel? -Moishe
