Roebic K-37 64 Oz. Septic Tank Treatment

Contains anaerobic spore-bearing bacteria selected, conditioned and cultured for use in septic tanks.

Resistant to soaps and detergents; they continually produce enzymes which digest protein, keep tank contents liquid and prevent over-accumulation of organic waste.

A single treatment is guaranteed to prevent clogging for 1 full year.

Use 1 quart for each 500 gallon tank capacity once a year.
