Horrible smell (for a hot minute) but works great!!
When we bought a new house with a septic system we were just learning the do's and don't. The plumber that pumped out the tank told us he uses this in his system at home. 1 bottle every season change (so 4 times a year) and he's never had any septic issues. It does smell horrible when you open it but thankfully you flush and they smell goes away in a few minutes. Shake the bottle good before opening. Pour in toilet and flush 2 times. The directions say to add to system when you will have limited water usage so we dump it in before we go to bed. Knock on wood we have had 0 septic issues in 5 years of using this product.

IT WORKS !
Have treated my septic tank with this for over four years now (every 3-4 months) with zero issues. Well worth it in lieu of costs to have septic tank cleaned/pumped out. Working for me.

You Cannot Go Wrong With Roebic Products
Roebic Septic System products have worked dependably for me for over 50 years. I've tried others without success and have always come back to the Roebic line. They work as advertised.

Used on a domestic sump
Did not dissolve as well as I had hoped. Lots of fatty deposit left after multiple treatments. Am ambivalent a to whether it is effective or not.
