I realize that this is purely for aethetic value, but i am thinking of getting Black CaribSea Substrate instead of the normal stuff. I just think that the colors of the tank will stand out better and all that. I am struggling with size grain too. Ive heard people say that the small grain makes it hard for particles to get trapped and the system can cycle them easier when they just lie on top of the sand. Ive also heard that good water flow through the sand is good too. Im assuming that the people who say the latter hand not considered the beforementioned persons' theory. Any ideas?
