sedimentation and coral stress

Hi!

We would like to measure the sedimentation rate threshold value for 
for a certain species of coral.  The lab expt. would involve 
introducing sediments into tanks over a 24h to 48h  period.  
My problem is finding a way of measuring parameters that 
indicate coral stress.  We don't have any sophisticated instruments.  
We have already thought of measuring respiration rates after 
incubation.  Another is measuring the carbohydrate or protein content 
of the water to quantify the amount of mucus produced-- assuming that 
the amount of carbohydrate/protein indicates the amount of mucus, and 
that the more mucus, the more stressed is the coral.  We are in dire 
need of suggestions.

Thank you very much for your kind attention.  Have a nice day!
