That one went right over my head. But maybe you've inadvertently stumbled onto a pearl making stimulant par excellence--- by pumping strong black organic coffee into lagoons or ponds. Perhaps that's what Prof. Berni's secret is !! He's Italian so maybe one morning he accidentally spilled some of his triple expresso into the bivalves' tank while waving around his cup trying to explain something to one of his students??
Coffee contains oxalic acid which binds calcium ions into insoluble compounds. I'm not sure if that's good or bad yet. It binds calcium but lowers the Ph level of the water. Hmmm...you could be on to something Ana. I'll have to ask Douglas(the eco-pirate) about this.
