Rocky sand
Hey guys,
The substrate that I am using is "arag" something, I can't remember because I threw the bag out. Anyways, it is fine sand mixed with chunks of coral and rock. It seems the big chunks of rocks and such settle at the surface, while the fine sand is at the bottom. This makes the sand look dirty as they have now become darker in color. Is there any way to ensure the big chunks aren't on top rather than scooping them out of the tank with a net?
