Spa Life Secure 500ml Prevents and Eliminates Scale Format
Preventing scale formation can protect the spa heater and other components.
Use Spa Life Secure after every water change to protect against stain & scale!
How Spa Life Secure Works:
The formation of scale in swimming pools is due to the precipitation of calcium or magnesium in the water as carbonates. There are several factors that influence this including: dissolved carbon dioxide, pH, total alkalinity, amount of calcium or magnesium in the water, and/or total dissolved solids.
