Scale Formation

Hard deposits (calcium carbonate) that form on pool surfaces and equipment due to excessive calcium or other out of balance water conditions.

1. Determine Cause:
o High calcium hardness levels.
o High pH.
o High Total Alkalinity.

2. Add BioGuard Scale Inhibitor

Initial treatment:
o 250 ml per 10,000 l of pool water when chlorine levels are at 1 ppm.
o Brush pool surface daily for 7 days.

o 25 ml per 10,000 l of pool water weekly.
o Brush pool surface frequently.
3. Lower pH and Total Alkalinity to correct ranges.
