The Rejuvenation Septic Kit from Lenzyme Trap-Cleer includes Field & Line Cleaner, Oxidizing Agent, High Count (Drainfield Biological Activator) and Lenzyme packets. This kit is designed to clean a conventional septic system with normal soil structure, including clay fields, and up to 150 feet of lateral line. Field & Line Cleaner cleans the pipeline and conditions the soil bed while the Septic Oxidizer’s ingredients attack the biomat buildup and have a reaction with the sulfides, according to the maker. The High Count (Drainfield Biological Activator) is blended to restore the biological activity, which is depleted during the oxidizing process. It also attacks leftover organics in the field. 800-223-3083; www.lenzyme.com.
