Our monthly easy flush dissolving packets are specially formulated to help break down waste and maintain a properly functioning septic system. This is the easiest and most efficient way to prevent expensive septic tank backups and drain field repairs. Just flush one packet down your toilet each month!
  • 🌿 SCIENTIFICALLY SELECTED BACTERIA CULTURES. Each packet contains billions of active bacteria cultures that are scientifically selected to produce, activate, and recharge the enzymes needed to reduce solids and decompose the different types of waste found in both the sludge layer and scum layer of your septic tank, and even out into the leach field.
  • 🌿 ALL NATURAL, ENVIRONMENTALLY FRIENDLY, & MADE IN THE USA. Each flushable septic treatment packet is all natural, with no chemical additives. They’re safe for all home plumbing lines, any black water system or cesspool, and both aerobic and anaerobic septic systems, so flush each packet down your toilet with absolute confidence!
  • 🌿 ELIMINATES ODOR, AND GREAT FOR YOUR RV AND BOAT TOO. Not only is this the best way to maintain a healthy residential septic system, but our concentrated formula dissolvable enzyme pouches are also ideal for use in marine holding tanks and camper toilets too! And because of the advanced digestion rate of odor causing bio organic wastes, they aid in controlling and getting rid of bad smells too. Your nose will thank you!
  • 🌿 PREVENTS EXPENSIVE SEPTIC BACKUPS AND REPAIRS. A small investment in our septic tank treatments help to prevent clogs and bulky buildup that causes septic overflow. The billions of bacteria in each packet digest solid waste, converting it to liquid, preventing costly repairs and frequent pumping.
