Check out the link in my signature about nuisance algae for help lowering dissolved nutrients. Shrimp live off of uneaten fish food more than anything, so they will be fine. You can always target feed them. Most snails live off microalgae mainly which needs very little nutrients to grow where macroalgae (like Caulerpa, hair algae, etc) need much more nutrients to thrive. It is unlikely that you would be able to lower nutrients so far as to kill off snails unless you are carbon dosing (not the same type of carbon as what you use in a filter).
