QUANTITY CONTENTS CODE
2 X 60 mL Biguanide Indicator 3994-H
1 Pipet, plastic, 1.0 mL 0354
Biguanide is a non-chlorine, non-bromine chemical sanitizer. It is more
stable than chlorine or bromine and has little chemical odor. Biguanide is an
effective bacteriacide but, unlike chlorine and bromine, it does not destroy
organic contaminants. Therefore, hydrogen peroxide is added to biguanide
pools on a regular basis to eliminate organic contaminants. The optimum
recommended level of biguanide is 30 to 50 ppm.
APPLICATION: Swimming pools
RANGE: 0–70 ppm Biguanide
INTERFERENCES: The only interfering substances that are likely to be
encountered in pool water are oxidized manganese.
