Safety and Usage Information
Safety and Usage Information
Hypochlorous acid (HOCL) has been widely studied for its ability to break down organic buildup through natural oxidation. Research shows that low concentrations of HOCL can significantly reduce organic buildup without damaging surrounding surfaces. Studies also show that sodium bicarbonate helps neutralize odor-causing compounds, helping improve freshness in enclosed systems.
Together, these ingredients help break down buildup, support cleaner tank surfaces, and reduce stubborn odors inside water systems.
