Why not feed my corals & bacteria with this nutrient source. Remember, nutrient recycling.

Yes, recycling is fine, and your corals can take nutrients, but only if the system is balanced. You can tinker with how many fish you have & how much you feed the tank in comparison to your biomass that takes up the inorganic & organic nutrients. But it's excess nutrients I'm thinking of. In a tank that's not intentionally 'balanced' or otherwise, the excess nutrients need to be exported so they don't build up.
We all recycle nutrients to one degree or another.
