well i was going to run a freshwater tank. but decided salty is more interesting. i have put some plain black gravel in my tank , but i have been told i need * coral sand * which i can get hold of cheap locally. but ... do i need to take all my gravel out and ONLY use coral sand ? or can i mix it ?
