Sirona® Phosphate Remover
Product Overview
A concentrated 3 in 1 spa formula designed to eliminate phosphate levels and prevent waterline scum without altering your water balance.
Spa technicians reach for Sirona Spa Care Phosphate Remover in this 16 fl oz bottle because it provides a concentrated 3 in 1 treatment that binds orthophosphates, clarifies hot tub water, and prevents waterline buildup. It reliably handles nutrient reduction without adding cyanuric acid or shifting pH (7.2–7.6), allowing sanitizers to maintain a stable free chlorine residual of 1–3 ppm.
