If you treat with herbicides make sure you let it kill the plant and it drops to the bottom. If you want to be proactive on the dead biomass on the bottom I would look to using muck remover bacterias or a small suction dredge. Removing live or dead vegetation is painful but people do it. Treat early on young plants and you will not have the extra dead biomass to worry about. I have a few clients where we used fluridone and the plants are dead yet floating on the surface. A small algae treatment or good rain will knock it down. Aeration and bacteria is the best answer to counteract the dead waste.
