Green Gobbler Septic Saver is one pod flushed once a month. We checked what the maker claims against its safety data sheet, the state additive lists and the EPA, and worked out what it costs at five retailers. We have not tested the pods in a tank of our own.
Some links on this page are affiliate links, and we earn a commission if you buy. That does not change what we report. Prices are snapshots from September 24, 2026.
If you have decided to use a monthly treatment, this is one of the cheapest on a state list. If you have not, read what the evidence says about septic additives first.
Check price on AmazonEach pod holds what Green Gobbler's FAQ describes as “a wheat-bran based powder containing dye and naturally occurring viable bacterial cultures” in a water-soluble film. The instruction is: “Simply drop a pod into your main floor toilet once a month and flush.” The label gives no larger dose for a larger tank.
One practical point from the FAQ: the pods only help a toilet that drains to the septic tank. For a toilet on a sewer line, Green Gobbler says the product “would not help prevent backups”.
One pod a month, so a year is 12 pods. Prices seen September 24, 2026, at a US location.
| Where | Price | Per month | Per year |
|---|---|---|---|
| Walmart, 12-month supply (12 pods) | $23.96 | $2.00 | $23.96 |
| Walmart, 6 pods | $12.57 | $2.10 | $25.14 |
| Home Depot, 2-pack (12 pods) | $30.96 | $2.58 | $30.96 |
| Home Depot, 6 pods | $15.98 | $2.66 | $31.96 |

We could not tie Amazon's price to a specific pack size on the day we checked, so it is not in the table.
Green Gobbler names no bacteria strains, gives no colony count and names no enzymes, on its own site or in any retailer listing we read. The EPA notes that this is common: strains “are often not identified on the label.”
The safety data sheet published for Septic Saver (revised November 2022) classes the product as not hazardous, with no signal word and a pH of 6.6 to 7.6. It lists no ingredients and does not mention bacteria or enzymes. It also describes a dark green liquid, while the pods contain a powder, so it may be a sheet shared with Green Gobbler's liquid Septic Saver. On safety it is reassuring. On what the pods contain, it tells you nothing.
"7-IN-1 SEPTIC WASTE DIGESTION", breaking down toilet paper, fats, oils, grease, proteins, sugars and starches
What we found: No strain names, bacteria count or named enzymes anywhere we looked: not on the maker page, the retailer listings or the Amazon bullets. There is nothing to check the claim against.
"our formula is safe for toilets, pipes, plumbing and septic systems"
What we found: Consistent with the safety data sheet, which classes the product as not hazardous, with no signal word and a pH of 6.6 to 7.6. It is also on Washington's approved additive list.
Can also treat "drain & leach fields"
What we found: The EPA says the long-term effect of biological additives "on the ability of soils to treat wastewater is unknown." We found no evidence either way for this product.
"Our Pods help neutralize the effects of detergents and bleach."
What we found: No source given. The University of Arizona Extension says bacterial additives "may not compensate for excessive use of antibacterial products."
"NEVER HAVE SEPTIC PROBLEMS AGAIN" (Amazon listing)
What we found: Overstated. Green Gobbler's own page pairs the pods with "occasional tank pumping", which is what the EPA says actually prevents problems.
Washington and Massachusetts only allow septic additives on their state lists. Green Gobbler Septic Saver is on Washington's list (December 2024), and four Green Gobbler products are on Massachusetts' list (February 2020). Both states say a listing means the ingredients are unlikely to cause harm, not that the product works.
Ratings read on September 24, 2026: 4.6 out of 5 from 1,582 ratings at Home Depot, 4.7 from 1,083 at Walmart, and 4.7 from 39,634 on Amazon, where the count is pooled across pack sizes. High ratings for a septic additive are hard to interpret: most buyers have no way to measure what is happening in their tank, and a system that worked before usually keeps working.
Independent coverage is thin. Bob Vila names the pods its best-value septic treatment after researching more than 25 products, without a hands-on test, and lists as a drawback that they are “incapable of clearing hair from the septic tank”. Family Handyman quotes a plumber who recommends them. We found no independent test.
On September 24, 2026 the pods were sold at Home Depot (single bag, 2-pack and 6-pack, in store and online), Walmart (6-count and 12-month supply), Ace Hardware, Amazon and greengobbler.com. Lowe's listed them as unavailable, and Target's site did not carry the septic pods. Green Gobbler offers a 30-day money-back guarantee on purchases from its own site.
The Septic Saver pods are. Their safety data sheet classes them as not hazardous with a near-neutral pH, and the product is on Washington's list of approved septic additives. Green Gobbler's Liquid Drain Clog Dissolver is a different, caustic product: see our drain cleaner guide.
One pod a month, flushed down the main floor toilet. The label gives no different dose for larger tanks. Green Gobbler says to use one pod in one toilet a month.

No. Green Gobbler itself pairs them with "occasional tank pumping". The EPA says a tank should typically be pumped every three to five years whatever you add to it.
