The main reason to feeding is to achieve optimum and constant denitrifcation process. If no feeding, the anaerobes have to search hard for food which might not be available or only in limited amount.
I never like coil type. Easily choke, low n inconsistant in performance. As for carbon n sulphur, there are both pros n cons. Generally, carbon based is the prefer choice for FW setup.
