The absolute best treatment for your system.
I’ve been using this product in my system every 6 months as part of my regular septic maintenance routine, and it’s been working exceptionally well. My system runs smoothly, and I’ve had zero issues with backups, odors, or drainage since incorporating this product into my schedule. This treatment is designed to support the natural microbial activity in your septic tank, and it does exactly that. After each use, I’ve noticed improved performance-especially in how quickly things drain and how fresh the system stays. No foul smells, no sluggish flow. The 28 oz bottle is the perfect size for my needs. I just pour it in every 6 months, and I’m good to go. It’s an easy, no-fuss way to extend the life of my system and prevent costly repairs. I also appreciate that it’s biodegradable and non-toxic, so I’m not worried about harming the environment or upsetting the balance in my tank.

Would Buy Again
Works great in the septic system. Been using this brand for a lot of years. When the tank was pumped 5 years ago, the guy commented that it had worked the way it was supposed to.

Bang for your buck!
THEE best to use. Have been using it for years. What is so nice is there are 7 treatments - yes 7 in one bottle. A great value for your money! Plus there’s no odor. A must buy!

Jelmar SEP-6 CLR Septic System Treatment
The reason for 3 stars is - no problems so far. I have been using this product for about two years now. My septic system is rather new having been installed approximately 3 years ago. I would imagine that no problems would have arisen even in that period of time if I did not use any septic system treatment, and living with just one other person the system does not see the use from a full family. I am not about to dig it up just to check it out. I based my purchase and use of Jelmar SEP-6 CLR on the many positive reviews I read about the product.
