Roebic K-37-Q-C1500-4 K-37-Q-C1500 Septic Tank Treatment Concentrate Safe for All Plumbing Systems, 32-Ounce, 32 oz

Works like a charm!!!

If you're already at the point of using this product there's a good chance that your septic field is toast but this help buy me a little more time until I was able to get the whole field fixed one thing is for sure it did substantially help reduce the odors

I’ve used this for a couple years now and it seems to help my septic so I will continue to purchase and use

I’m not sure how well this works because we can’t “see” it working, and right after I used it, we replaced the drain field, which turned out to be the original problem with it backing up. I don’t necessarily remember the smell, so I guess it wasn’t too awful. I DO know that the simplicity of pouring a bottle of stuff into the toilet periodically in order to create peace of mind is priceless!

Our septic guy highly recommended this product and he’s been in business for over 40 years.
