Dear Emily,

I don’t have personal experience but have read one can use Alizaren red or Calcofluor white to die corals and coralline algae with variable success so perhaps you could experiment with these. 

Regards, Sean

Hi all,

Does anyone have experience with fluorescent dyeing sediment? I am interested in dyeing small quantities of sediment to be used as tracers for a series of experiments involving coral reef sponges. The sediment will be gathered from a shallow coral reef and will range in size from ~35-150µm and should fluoresce under UV light. The application of the dyed sediment will be *in situ *so non-toxic materials are preferable.

Another complication is that the staining process will occur on a remote field site with few resources so ideally all materials will need to be airline approved.

Any suggestions would be greatly appreciated!
