Your tank runs on bacteria. Septy sends down more.

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.

Your septic tank is a living system

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.

The science

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.

Drop one pod monthly

Flush one pod down the toilet closest to the tank, once a month. That is the whole routine.

Cultures go to work

Beneficial Bacillus cultures and plant-based enzymes break down the organic matter that causes buildup and odors.

The tank stays in rhythm

A steady monthly dose supports the bacterial balance between professional inspections.

Septic-safe by formulation, not just by label

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.

RV and boat holding tanks

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. A pod per month keeps a holding tank on the same rhythm as a home system, wherever the season takes you.

Frequently asked questions

How often do I use Septy?

Once a month. Drop one pod down any toilet, flush, and you're done. One jar is a 12-month supply.

Can I subscribe and save?

Yes. Natural House offers a Subscribe & Save plan that ships Septy automatically each month and saves you on the one-time price. You can pause, skip, or cancel anytime from your account.

Is Septy safe for all septic tank sizes?

Yes. Septy is formulated for all residential septic tank sizes. The Bacillus strains colonize and support the microbial balance in the tank regardless of volume.

Does Septy work through garbage disposals and high-efficiency washing machines?

Yes. The probiotic spores survive normal household plumbing conditions and appliances, reaching the septic tank intact.

How long until I notice results?

Most customers notice reduced odors and improved tank performance within 60–90 days of consistent monthly use.

Can I use Septy if I also use bleach occasionally?

Occasional bleach is manageable, but frequent use disrupts the bacterial colony Septy builds in your tank. For best results, use oxygen-based or probiotic cleaners for daily household cleaning.

One pod a month. One jar a year.
