Septy is a once a month probiotic pod for septic systems and RV holding tanks. Drop one pod in, and billions of beneficial cultures go to work supporting the bacterial balance your tank depends on. One jar is a full 12 month supply, made in Michigan City, Indiana by a team with nearly twenty years of experience formulating beneficial Bacillus strains.
Made for home septic tanks and for RV and marine blackwater holding tanks.

A septic tank is not just a holding tank. It relies on billions of beneficial bacteria that break down waste day and night. When those bacteria are healthy, the system works. When they are depleted, solids build up faster, odors creep in, and pump-outs get more frequent and more expensive.
Bleach-heavy cleaners, ammonia-based formulas, and antibacterial products all share one problem: they do not know the difference between the bacteria you want gone from your toilet bowl and the bacteria your tank depends on. Used heavily, they disrupt the balance the whole system relies on. Septy takes the opposite approach: once a month, it sends down more of what the system already uses to work.
Natural House cultures come from a biotech company that has spent nearly twenty years isolating and formulating beneficial Bacillus strains. The same Bacillus strains that break down residue on a counter or in a toilet bowl also break down waste in the tank, which is why a probiotic treatment does not fight a septic system the way a bleach or ammonia-based cleaner can.
Flush one pod down the toilet closest to the tank, once a month. That is the whole routine.
Four ingredients, nothing extra: active Bacillus spores carried in a mineral base of sodium bicarbonate, sodium carbonate and sodium chloride. The spores stay dormant on the shelf and activate in the water of your tank, where they join the natural bacteria already living there.
A steady monthly dose supports the bacterial balance between professional inspections.
Septy handles the tank. These daily cleaners send the same beneficial cultures down the drain, so everyday cleaning works with the system instead of against it: Flushy, Sinky, and Surfy.
Septy is labeled for RV and boat holding tanks as well. The same logic applies: avoid bleach and harsh chemistry, and use a treatment that supports breakdown instead of fighting it.

Septy works inside the tank, so there isn't one sign to watch for. Use one packet a month and keep your pumping schedule. Your septic pro is the best judge of how your tank is doing.
Use one packet monthly. The canister contains 12 packets, a one-year supply.
Yes. One canister is a full year, so Subscribe and Save sends a fresh canister once a year at 15% off. Flushy and Sinky can ship on their own schedule. Pause, skip or cancel anytime from your account.
Yes. Septy is formulated for all residential septic tank sizes. One pod a month is the right dose across that whole range, because the formula goes to work on the paper, fats and greases entering the tank rather than on the volume of the tank itself.
Yes. The probiotic spores survive normal household plumbing conditions and appliances, reaching the septic tank intact.
Occasional bleach is manageable, but frequent use disrupts the cultures Septy adds to your tank. For best results, use oxygen-based or probiotic cleaners for daily household cleaning.
Give the tank more of what it already runs on. Get Septy.
