Patented Inter-Core Technology® works to allow LAGOON SHARKS to quickly attack and biodegrade gasoline, diesel fuel and other organics in the sludge at the bottom of lagoons, treatment ponds and retention ponds. Features 10 billion CFU/gram of specially selected gram negative and gram positive bacterial strains that provide a combined quick-release slug dose with a slow release block that works over 4 – 10 weeks. While attacking the hydrocarbons, it also reduces sludge 20 – 50% in 60 to 90 days.
