APPLICATION FOR SWIMMING POOLS
Ensure all pool equipment is working properly. Clean or backwash filter following manufacturer’s directions. Adjust pH to between 7.2-7.6. In outdoor chlorinated pools, add stabilizer to establish a minimum level of 30-40 ppm to reduce the degradative effects of sunlight upon the chlorine residual. Check for metals and if present add a stain and scale inhibitor to prevent staining of pool surface due to metal. Maintain sanitizer residual in accordance with label directions found on your sanitizer of choice. This product is effective in controlling the growth of green and blue-green algae. When using other products as outlined in directions for this product, always follow directions on those products.
INITIAL APPLICATION
For an initial application, pour directly into deep end of pool at a rate of 16 fl oz of this product per 25,000 gallons of water (2 ppm).
MAINTENANCE
Pour directly into deep end of pool at a rate of 4 fl oz of this product per 25,000 gallons of water (0.5 ppm) every 5-7 days depending on weather and use factors. After each rain of consequence, add 4 fl oz of this product per 25,000 gallons of water. Even when the pool may not be in use for periods of time, algicide additions must be made since a heavy accumulation of algae growth is difficult to remove. Recirculation accomplished by running the filter will ensure rapid dispersion of product. Wait at least 15 minutes after application before entering pool.
