Any gurus out there who can tell me whats going on with my sand? TIA!
Is this normal the appearance of the sand look purplish with some green and bright orange? is this coralline algae?

Hi to all i have a 30g cube mixed reef 8 months old. i was planing to replace my old rock scape and sand to new rock scape and sand. the plan is i will remove my corals and LR and shipon my sand, then i repace it with new sand and put the new rock scape and place all my corals. do i need to cycle again my tank for replacing all my LR and sand to new one? TIA!
