 I would like to measure light intensity and light quality at various
water 
depths in an aquarium (say 15 - 20 gal size).  Can anyone advise me on
what 
kind of specific equipment I need, and who carries it?  

Dear Kathleen,
I believe that LI-COR Instruments in Lincoln, NE has a quantum sensor
designed for underwater measurements.   See http://www.licor.com/
