We're used to the speedy way chemical septic sytem treatments work. In some cases, using the natural process of enzymes to break down organic matter may take slightly longer.

DIRECTIONS FOR USE: Our 10.3 oz. box is a once-monthly dose for up to 1500 gallon capacity septic tanks. Pour the entire contents of box into toilet. Flush twice. Be sure to recycle the empty box! For best results, we recommend adding Earthworm^® Family-Safe Septic System Treatment & Cesspool Cleaner at a time when plumbing will not be immediately used, such as bedtime or before leaving home. Use Earthworm^® Septic once a month, every month, to maintain your system.
