Review on 🚽 Roebic K-97 Main Line Cleaner: Powerful Biodegradable Bacteria to Tackle Paper, Fats, and Grease in Sewer and Septic Systems - 32 Ounces by Ryan Farias

I bought two bottles. I follow the directions and double the dose for 4 nights. It's been a week now and I don't see any change in my slow draining line. I look down the main drain, there is still an inch of sluggish waste deposited at the bottom of the drain. So two bottles of K97 did nothing to clear my main line. I am currently giving one star. I will check it again in 7 days, if the condition improves I will increase the rating. I forgot to mention that this product smells like this. Too bad I have to wear a mask and face shield when pouring it down the drain in the floor. This product is useless. I thought this product would be more eco-friendly but I think I need to go back to cheap instant power. Or maybe I should try Green Gobbler, it claims not to kill good bacteria. I still have hope that Green Grobbler won't destroy the K97 bacteria.
