Not likely that you'll be feeding fish that are large/hungry/messy enough to produce that much nitrate, and you wouldn't want to feed excess, anyway.
Hop over to aquaticplantcentral.com and navigate to the Fertilator program. It'll help you calculate the right amount of dry chemicals to use.
Some people have good luck using the AquaSoil without ferts for a while, but you'll likely need to at some point.
