Shock Treatment
Shock Treatment is a term used to refer to the "burning out" (oxidation) of part or all of the ammonia, chloramines, and other combined chlorine compounds in the pool water so that the free residual chlorine reading can be maintained. It is recommended for outdoor pools to be shock treated on a weekly basis. Indoor pools should be shock treated once every three to four weeks, or when the combined chlorine level exceeds 1 PPM. (Use OPAquatics Taylor Test Kit to determine total chlorine level.) Chlorine odor, hazy water and eye burn are indications that pool water needs to be shock treated. This is accomplished by adding an extra large dose of chlorine to the pool.
Formula:
One (1) pound of OPAquatics Calcium Hypochlorite per 10,000 gallons of pool water...or
One (1) gallon of liquid bleach per 10,000 gallons of pool water.
OPAquatics Oxy-Brite or OPAquatics Oxone (Mono-persulphate) are optional methods for "Shock Treatment" of swimming pools. Granular oxidizing agents, OPAquatics Oxy-Brite or OPAquatics Oxone "Burn Out" organic material in the pool, maintain clarity, and leave no residue. They contain no chlorine, no calcium, and are effective in all normal swimming pool water. Because they contain no chlorine, there is NO waiting period to use the pool after the "shock treatment." OPAquatics Oxy-Brite and OPAquatics Oxone are not recommended for algae treatment.
Formula:
One (1) pound of OPAquatics Oxy-Brite per 10,000 gallons of pool water... OR
ONE (1) pound of OPAquatics Oxone per 10,000 gallons of pool water.
**The use of chlorinated isocyanurates (concentrated granular chlorine) is not recommended for shock treatments.
