💬 Southern Leisure Says
This is a strong option for customers using a bromine sanitation routine instead of chlorine or FROG @ease SmartChlor. It is especially useful when you want a product that both sanitizes and oxidizes in one step.
For best results, do not chase sanitizer readings without checking water balance first. pH and alkalinity have a big impact on how well sanitizer performs and how comfortable the water feels.
