Three Jobs in One: Our liquid bio-enzymatic formula is supercharged with additional enzymes, making it extremely effective. Combined with a lavender deodorizer and tank cleaning capability, this product gets the job done.
Liquids Outperform Powders: Powders and powders in packets clump at the bottom of the tank, build on sensors, and clog lines over time. EcoStrong's super-concentrated lavender-scented liquid disperses instantly, leaving no odors, residue, clumps, or clogs.
