Natural Chemistry Yellow Out

Add directly to the pool 2 pounds of Yellow Out per 15,000 gallons of pool water.

1. (a) NEVER pre-mix Yellow Out with chlorine. (b) NEVER add Yellow Out to a bucket or pail. (c) NEVER vacuum pool immediately after application. (d) NEVER add to skimmer basket or filter suction line. A very strong reaction with chlorine can occur if not mixed in pool. Circulate pool water through filter and, for best results, brush pool well before product application.
2. Shake well to break up the lumps (product lumping in transit is normal). Adjust chemical balance to: pH ≥ 7.8, alkalinity 80-120 ppm, cyanic acid 25-75 ppm and chlorine level 2-2.5 ppm.
3. Add directly to pool 2 pounds of Yellow Out per 15,000 gallons of pool water. Spread half of it along the perimeter of the pool, starting where the algae is the thickest. Concentrate the rest directly over the problem areas. Never add more than what is recommended.
4. Wait 5 minutes, then add directly to the pool 2 pounds of powdered chlorine (or equal) per 15,000 gallons of water.
5. Circulate pool water with filtration continuously for 24 hours using only the main drain if possible. Repeat step 4, adding additional chlorine after 12 and 24 hours.
6. Return equipment and chemical balance to normal after clean up.
