PristineCheck 32 oz: Calcium Sequestrant & Water Prep for PristineBlue
PristineCheck is a water preparation treatment from the PristineBlue system by Innovative Water Care. This 32 oz bottle sequesters calcium and other dissolved minerals in your spa water before you add PristineBlue, ensuring the copper-based algaecide works at full effectiveness.
Key Features & Specifications
- Type: Calcium sequestrant / water preparation treatment
- Size: 32 oz (quart)
- Purpose: Binds calcium and minerals before PristineBlue application
- Usage: Add before introducing PristineBlue at startup and during bi-weekly maintenance
- System: Essential component of the PristineBlue water care program
Why Water Prep Matters
Dissolved calcium and minerals can interfere with PristineBlue’s copper ion formula. PristineCheck binds these minerals so they cannot react with PristineBlue, keeping the copper ions available for algae and bacteria control. This is particularly important for spas filled with hard water.
How to Use
For spas, add 10 milliliters per 100 gallons of water. Circulate for 2–4 hours, then clean or rinse your filter before adding PristineBlue. Use at initial startup and during regular bi-weekly maintenance when calcium hardness is elevated. Always balance pH and alkalinity before applying.
