LaMotte Pool & Spa Owner's Handbook - Manual (Page 29)

ADJUSTING CHLORINE
It is recommended that dry chemicals first be mixed into a generous
amount of pool water in increments of about two pounds (1 kg), and the
predissolved mixture be distributed evenly around the pool unless
directed otherwise.
Precautions
n
Never add water to chemicals; always add chemicals to water.
n Always follow manufacturer’s recommendations and warnings
on product labeling.
n
Never mix two chemicals together since their pH might vary
and could cause an explosion or fire.
Best results are obtained by predissolving granular chlorine products,
especially if you have a vinyl pool. Trichlor is erosion fed through
skimmers or floating passive feeders. Simply add one Trichlor stick
or puck. Do not try to break pucks, since these can burn skin.
