Ultima® S.O.S. is a multi-functional shock treatment that oxidizes and boosts free chlorine concentrations creating clean, clear water fast. Its unique formulation contains a powerful clarifier, oxidizer and chlorinating agent and will not affect water balance.
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
Always add with pump and filter running to ensure complete mixing and good circulation. Ultima® S.O.S. is completely soluble and dissolves quickly, so no premixing is required. Broadcast Ultima® S.O.S. uniformly over the surface of the water, adding about two thirds of the total dose into the deep end of the pool. Apply product when swimming pool is not in use. Swimming may resume as soon as 15 minutes after product application, provided the chlorine residual concentration in the pool is between 1 and 4 ppm. Reentry is prohibited above levels of 4 ppm chlorine due to risk of bodily injury.
1. Add Ultima® S.O.S. weekly at a dose of 1 pound per 10,000 gallons of pool water.
For Pool Opening and Closing:
1. Add Ultima® S.O.S. at a dose of 2 pounds per 10,000 gallons of pool water.
2. This dose will provide sufficient oxidizer to eliminate most of the contaminants that accumulate in pool water, and will immediately raise the free chlorine concentration by 2 ppm (parts per million) in 10,000 gallons of pool water.
