I'm about to set up my first system, and wanted to know the best way to go about cleaning all of the containers. Any soaps, cleaning agents? I've got some Food grade Five Star cleaner I use for when I make beer; would that work?
No soap. Any residue leftover from washing with soap can coat fish gills and kill them, even if it is food grade. If you bought containers that held food grade materials, then just scrub them and rinse them out with water.
