I doubt that a high density of filtering clams will cut back on a nutrient overload. In fact the "clams" may contribute to more dissolved nutrients as high numbers of zebra mussels are suspected to be doing in Lake Erie. Manure from mussels is probaly quite fertile containing soluable nutrients sourced from rapidly decaying plankton and detritus.
