The first few half-bottles only stunned the outer edges of the bacterial colony. The tank’s ecosystem had resilience; a few trillion microbes survived deep in the sludge layer. But after the eighth or ninth treatment, the pH in the tank shifted from a healthy 6.5–7.5 to a toxic 10.5. The heat from the chemical reaction killed off the sensitive Bacteroides and Clostridium strains first. Within 48 hours, the tank’s digestion rate fell by 80%.

For slow drains, use a plunger, a mechanical snake, or a bacterial enzyme treatment designed for septic systems. And if you must use a chemical cleaner, call a pumper first—because the only thing worse than a clogged pipe is a sterilized tank. The heat from the chemical reaction killed off
