Directions for Use
It is a violation of Federal Law to use this product in a manner inconsistent with its labeling. Read entire label and use strictly in accordance with precautionary statements and directions.
Prior to Application
1. Ensure all equipment is working properly. If necessary, clean the filter system.
2. Adjust pH between 7.2-7.6.
3. Establish and maintain proper chlorine or bromine levels. In chlorine-treated pools, add stabilizer to establish a minimum level of 30-40ppm of cyanuric acid to reduce the degrading effects of sunlight on chlorine residual.
4. Vacuum leaves and any other foreign debris from pool.
5. Brush visible algae thoroughly from the pool’s surface with a surface-compatible brush.
To Prevent Pool Algae
1. Initially apply 8 fluid ounces of this product per 10,000 gallons of pool water with pump and filter operating.
2. Thereafter, for weekly application intervals, add 1.5 fluid ounces per 10,000 gallons of pool water. For two week application intervals, add 3 fluid ounces per 10,000 gallons of pool water every other week. Apply more often if pool volume is diluted by heavy rain, frequent backwashing or partial drain/refill.
3. Wait at least 15 minutes after application before entering pool.
Treament of Visible Pool Algae
1. Apply a shock per label directions.
2. Allow to circulate for 1 hour.
3. With pump and filter operating, apply 16 fluid ounces of this product per 10,000 gallons of pool water directly to the pool water in areas of heaviest algae growth.
4. Continuously circulate pool water for 24 hours.
5. The next day, thoroughly brush pool surfaces.
6. Prior to re-entry, test chlorine level. Do not enter pool until chlorine level is between 1-4ppm.
7. In cases of persistent algae, repeat brushing and product application after 2-4 days.
8. The use of a filter aid will enhance filter efficiency and algae removal.
9. Chemically cleaning the filter 3 to 4 days after treatment improves results.
