LaMotte Pool & Spa Owner's Handbook - Manual (Page 37)

ADJUSTING CYANURIC ACID
It is recommended that dry chemicals first be mixed into a generous
amount of 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.
Usually a 30 - 50 ppm concentration of cyanuric acid will produce good
chlorine stabilization. However, your service professional may have
a different recommendation. Usually cyanuric acid is added to a skimmer
and travels to the filter where it may take 24-48 hours to completely
dissolve. Determine how much cyanuric acid you wish to add and find this
number on the left-hand side of the table. Match this with the pool or spa
water volume listed at the top of the table. Keep in mind that dichlor
and trichlor products will add cyanuric acid as well.
