Initial slow reaction but now very good
I recently had my septic tank emptied and soon after there was quite a bad smell as it started to fill again. I put one sachet and didn’t notice a difference so after two weeks added another and within days the smell had gone. I will now follow the monthly regime. Seem to be working well.

Good product, easy to use, just drop one in a toilet every month. It helps with keeping your septic system 'healthy' like probiotics, and is better then Rid-X. I have been using this for over 2-years with no issues. Also keep non-biological stuff out of the system, like organic materials such as vegetable peelings and food stuffs.

I tried other products before when we bought our house it was empty for 18 months, so this was more about starting the system over. I did shocks & a tank restart product, leach line cleaner, it was ok but I until the dreaded toilet paper back ups in the lines. I bought this & not one toilet paper issue at all. I like that it holds up pretty well with detergent and such. I I also have a water softener that uses potassium chloride & I think that was part of the issues with the bugs I used before. I do limit my bleach use but I do get food, fats, & kitchen scraps with my powerful garbage disposal. I also add my coffee grounds because those are like bacteria nurseries & help cut grease. Not one back up or even issues if I am gone for a few weeks. I highly recommend this & the price is just a bonus, given how well it works.

Overall, does what it says it will do indeed you can flush it just one time I like doing it twice. I feel like that gets it further down the pipe I try to use it weekly. I know it doesn’t recommend that but you know what’s it gonna hurt we like it

I really like the ease of using these packets over the powder. Very fast delivery.
