FIGURE 99.

Biofilters occasionally need stirring or agitating to prevent clogging, and occasionally need rinsed if the solid waste has clogged them, creating anoxic zones. For cleaning, not all the media has to be removed. Removing and power washing approximately 75 percent of the media is usually sufficient. Leaving some media will help jump start good bacteria growth after the cleaned media is returned. Avoid using standard type cleaning solvents. Cleaning solvent residue remaining on the balls can kill the good bacteria and introduce undesired contaminants into the aquaponic system.
