Per pound of wet weight will work for this scientist. wink You also realize that phosphorous is the limiting factor in regards to plankton production? :p Sheesh sorry but I really would like to see scientists stay within the realm of science? beathead BTW the prawn and crab pops down south in the canal are doing very very good beer ! Sorry but the sky ain't falling...just as I pointed out last year when chicken little cried it was. wink
