90-day, gradual-release biodigester block. Formulated with a high concentration of naturally-occuring bacteria for low to medium flow applications. Digests fats, oils, grease, and other hydrocarbons quickly while improving the overall health of the system. Use in large laterals, settling tanks, lift stations, grease traps, lagoons, oxidation ponds, aerobic digesters, and anaerobic digesters. Eliminates the need for chemical metering pumps.
