NuTank septic system treatment from J & J Chemical Co. is designed to replenish the enzymes in a septic tank. With high concentrations of billions of specific bacteria, it is engineered to break down solids, scum and sludge. Monthly use will help reduce the potential for backup and repairs such as drainfield damage, and it boosts the progression of solids decomposition and helps keep tanks and drainfields working adequately, according to the maker. The recommendation is to toss one self-dissolving packet into a drain or toilet monthly and wash or flush it down. It is safe for all plumbing and environmentally friendly, designed to be resold by septic pumpers, prepackaged in 12 packets per jar and 12 jars per case. Company contact information can be added to each jar. 800/345-3303; www.jjchem.com.
