Note: Dosage is a function of surface area rather than of water flow. See product label (Mexel S.A 1997b).
Standard dosage is for a short period each day, typically 4 ppm for 20 min per day.
Daily dose is determined by the amount of internal surface area to be protected and is calculated at approximately 0.033 lb or 15 g per day (1 lb or 454 g per month) per 100 ft2 (9.3 m2) of surface area. Inject dose into circulating water at a rate to achieve a concentration of 1 to 4 ppm: 1 to 4 pints of product for each 125,000 gal of water, or 1 to 4 L per 1,000,000 L water.
A dose of 12 mg L-1 per day in flow-through inhibits veliger settling.
