Dear Coral Reef List: 

Does anyone have information or experience using Alizarine  
Red-S stain for determining growth rates of calcareous algae?   
I need to know what concentration, how long to stain and  
what time of day gives best results.  I will be working specifically  
with Halimeda and am concerned with the stain interfering with growth  
rates and CNP tissue content. 

Thanks in advance for any advice you can share.
