How to do a measuring session
The Anacostia's Freshwater Mussels - important for filtering water

From an AWS mussel presentation: The two tanks started out w the same amount of dirty haze. The mussels in the left hand tank have filtered out all the haze in less than an hour's time. An adult mussel can filter 10-20 gal of water a day. This activity is a key strategy in cleaning up the Anacostia River.
